Thanks for another fun season Wally.

After lots of poor results by me and some bad luck I finally put a race together and just snuck away with the win, In Qualy its the first time Ive been anywhere near my PB in qualy. It was probably the first time I was faster in qualy then in the race too all season.

From pole I had an ok start and just decided to take the inside hoping nobody would get around the outside, I saw a little carnage in the mirror and had a reasonable gap after the first lap. From there on I decided to just keep going til it ran out of fuel hoping to have better rubber at the end and hopefully hang on to the lead after both stops.

The first stop on lap 15 GB was much closer then Id hoped and I only just hung onto the lead into t1, then I wasnt sure If I wanted to go longer on the second stint or come in early to avoid GB getting ahead with an undercut. I pitted the lap after him and this time I exited alongside but he got me into t1. I then just tried to hang on knowing hed be pushing hard trying to get away, then once hed used his tyres a little I could see I had a bit more pace. It took a few laps to get past including one failed attempt where I spun him then waited to let him back past. Another couple laps and finally I got past, then just tried to get enough of a gap to be able to hang on and it was just enough. Luckily the Lafa was the slightly better car so I had more hope against him.

Well done to Stan and Matthew on their seasons, Matthew had the pace pretty much all season with lots of wins and poles. It was a bit of a shame that Matthew and Jeremey both had incidents on lap 1 this race as it would have been quite a bit trickier if they were also up there pushing along.

The hardest p6 of my life haha was happy scoring a pb on my last lap of qualy just missing out on pole.

Was planning on a nice simple race staying out of trouble and bringing the car home for the title but that all came to a quick end on the exit of t1 lap 1 haha got launched into a wall off the side of guybrush's car after what was the slightest of touches, so from there the car was rubbish but still able to be driven straight so I regathered myself and charged on lol. Picked off a few cars to get to about p7 I think a few seconds off Wally and stan (my bitter championship nemesis!! :P ) eventually got on the back of wally with phil after his mishap and we battled out for a bit until phil lagged into my car at the last turn so I lost another 6 secs to wally again which took a few laps driving like a mad man to get back again. Came out fairly close to wally after my second stop but had Jeremy to contend with too who had good pace so he ended up clearing us both, after a few laps I managed to get around wally for p6 and that's where I stayed.
Was a rewarding race despite its difficulties lol car was stuffed and with the title on the line I had to drive it like I was on a qualy lap for 35 laps to salvage any kind of result that would secure it lol so I was pretty happy and exhausted with that p6 lucky it was enough :) had a blast this season so thanks to everyone for making it happen!

Congrats to marty on the race win too after a hard few rounds, waited for the last race to come good lol

Pretty poor night from me. Was sat nicely behind Gratulin up until lap 8 where I spun off on the downhill section loosing a few places, then I did exactly the same thing on lap 9 putting me in last. Had another spin on that section later on and tried desperately to not go back onto the track as I knew there were people coming up to lap me, but of course ended up stopped right on the middle of the track. Luckily Bird saw and avoided me and I managed to get off the track.

Lots of people lapped me, then I had Freezer behind me but I assumed he was also going to lap me as I hadn't taken my last stop and I thought I was in last, but then we both pitted together, I came out in front but went wide on turn 1 and he went past. Then spent many laps chasing him down but couldn't get past, tyres were getting slippery and eventually he lost his line on lap 34 and went wide, I braked too hard to make sure I was inside him and also went off, but I was able to rejoin quicker and got ahead. Despite the poor start the chase at the end was pretty fun.

It was a clean race for me. I kept up with the lead pack for a little while, behind Stan for a while, but couldn't keep up. I was going to do two long stints, but midway through my second stint, Guybrush came out from a stop behind me. Guybrush hassling me on fresher tyres? No thanks. So I got to about 13 laps from the end and then pitted early for a full tank run home. A bit later, Jeremy and Matthew caught up and made clean passes, helped by me undesteering wide a bit.

Thanks to lapped racers for making it easy to pass them.

That right hander at the bottom of the hill is one of the great racing corners.

Really glad I gave these cars another try after a washout of a season for me. Finally got the hang of the longer races by just focussing on consistency and keeping it on the track. I also got a bit lucky in the first few laps when there were some collisions and slides. But I think because I was just trying to stay alive helped.

Simone and I exchanged mistakes for a while until he got ahead on the first pit stop. Managed to do a better pit stop second time around (missed the box first time and had to back up). Then I followed Bacchulum to the end. Thanks to Bacchulum for giving me a smooth driver to follow in the last 10 or so laps. I wouldn't have kept my concentration without his car to focus on.

Got 'Most Consistent' AND 'Hunter' award for the night - Yeah!!

And thanks to Wally for a great season. You were correct yet again in your choice of season format. I learnt a lot after really struggling with these cars.

Post by: Guybrush Threepwood on July 15, 2015, 09:10:18 AM
Very enjoyable racing thanks Wally and everyone.

I started the race third on the grid and got a reasonable get away, sidling up beside Matthew and right behind Marty into T1.  I held the inside line behind Marty and Matthew and I were heading into T2 side by side.  Not sure what happened; I saw I had some room on Helicorsa and moved over slightly so I could take the corner without under steering to the other side of the track, but it seemed that just after I'd moved over Matthew may not have seen me and came over as well?  Anyway, one of those incidents.

So that sent Matthew and I flying.  I was able to stay on track, albeit losing a bit of speed and then I saw a Ferrari coming up behind so I gave some room on the inside though T3 but the slippery track resulted in that car under steering into me and sent me across the grass, coming out behind Phil8 and Bird.

I was stuck on their tail for a few laps before getting a good run out of the chicane and throwing it up the inside of Bird into the hairpin.  Then I followed Phil8 for a few more laps before I got fairly close and managed to take advantage of some under steer from Phil.

Pitted at the end of Lap 9, then had some clear air to put in some decent laps.  With the damage sustained earlier in the race though it felt like I didn't have much front end grip.  Anyway, did what I could and came up just metres behind Marty once he had stopped.  We ran around together for a bit and came up to lap Benana and Freezer who were having a battle of their own.  Not sure if Feezer didn't see the blue flags (?), but seemed to almost give me the jump on Marty, however Freezer let Marty past on the straight down to the chicane, but may not have realised I was also lapping him as I followed Marty into the chicane assuming Freezer was letting me by as well, however not to be the case and we collided.

I kept pushing on though and then pitted again before Marty.  Again I got a decent undercut and managed to come up side-by-side with Marty as he exited from his final pit stop, however took the lead as I had the inside line into T1.  Kept Marty behind for a little bit.  Got a little tap into the hairpin, but Marty was good enough to wait for me and the battle resumed, however not for long as I think a lap or 2 later he got  past.  From then I was just trying to put in some decent laps to keep up in case he made a mistake, which wasn't easy on worn tyres and a damaged car but a bit of fun.

I think we ended up about 2 seconds apart across the finish line, but those 2 seconds seemed like a mile when we were racing and an impossibility to reduce that gap!

Good fun and well done to Matthew for taking out the season, StandDaam for a well deserved 2nd and Marty for a late charge to 3rd.  I only completed a few races but the format seemed excellent - a good mix of sprint / reverse grid / distance races.

I had a great race.
Managed to avoid the early accidents, then chased Guy & Jeremy (I think). 
I was able to stick to Guy for a good while, then he went to pit early.   
Later at my pit, I've been staring at the tyre selection for a good 4-5 seconds, before making the executive decision it'll not be the street tyre :)

Even later I had a stupid off at the fast downhilll section, losing another 4-5 seconds.  Stan was nicely chasing me in after that mistake, for a while.

So, lost around 8-10s on stupid things, and I've finished 10s behind Guy.  How about that.

Thanks for the hard work, Wally!

Yeah, you had some really good pace Bird.  I was struggling to pull away from you.  I was on 3 warnings from PLP and was trying to get a 10 second gap to you (I think this is the penalty?).

Very good race!  I`ll be honest with you guys the last 3 laps i had nothing left in terms of stamina,concentration and .....vibrations...lol...no i was stuffed seriously.Very close field i do not think i could have done better  i have been running the whole season with the default set and probably i could have been faster if twitching the set but ,just do not have time to play around these days.
Fantastic start with frantic duels in the first few laps,too bad i lost it touching those horribly noisy curbs  i slid 100 mt without damage but .soon after that i got involved in an accident i the last corner which slowed me down even further.
Great chase and battle with bacchulum and gratulin(good fun!!) but i could not put my nose in front of them.
Good fun guys!!!

BTW I removed all Python apps except for PLP for this race and did not have a single stutter or warp.

Could I suggest that everyone try this in next week's trial race?

Congrats to Marty for finally getting a win this season!!  :D (and to GB n Bird as well!!)

A bit of a quiet night for myself, nestled in between Bird and Wally for a lot of the race. Didn't quite have the pace to challenge Bird. Ended up getting run down by Jeremy (he had good pace!!) towards the finish, came home in 5th.

A big congrats to Matthew for taking out the comp!!. My nemisis!! proved to be too fast and consistent throughout the season, a well deserved victory for sure.  :D

Cheers also to Wally for doing the organisings, stella job as always.

Do you have AC on a secondary drive? I used to get frequent stutters with Helicorsa, and the developer told me it was probably due to the game being on a secondary drive. Apparently it's not possible to cache images used by apps, so at times where my drive would have gone into sleep mode, if the app needed to display an image it would need to wake the drive up which would cause the stutter. Guess this would be the same for any app that displays images in different scenarios.

I didnt get any warps and the only car I saw warp last race was freezer. I was kind of glad when I got past him when lapping him as his car did jump back a few times as I was closing. I dont think his ping looked that high but I dont remember exactly what it was at the time.

The one odd thing was I looked at the replay last nite and the contact with Guybrush and me on my replay we never actuallys touched. I did get slight damage to the front and he did spin but there was still a bit of a gap. It could simply be lag or even collision box not quite right in one of the cars as our pings were fine and contact was at the slowest part of the track. It would be interesting to see if on his replay he actually sees contact.

He was jumping around a bit when I was behind him, but his ping was stable at around 17ms

Post by: marty on July 15, 2015, 11:47:50 AM
Thats an odd one if his ping was stable at 17ms, I really didnt get a chance to look too closely at his ping as I was fairly busy at the time, trying to find a way past him with a bit of warp and another car ahead while GB was trying to sneak by. If his ping was stable then maybe something else was causing his warp, I know in some past races I saw his ping climb but I when I looked it didnt look too high. He was behind Benana at the time so he also would have seen the warps in his mirror.

This is why I am suggesting we do a test next week with everyone turning off all Python apps except PLP to see the impact the Python stuff has. I am guessing it is a large part of the warping problem.

Average night for me.  Qualified 9th but wasn't all that quick so focused on keeping it clean.
Plugged away for most of the race watching my fuel with the pre race calculator indicating 1 full tank divided by 14 laps was 6.1 l/lap which I kept to however at the 13.5 mark I was almost dry and end up coasting the last few corners out of fuel and managed to just sneak into the pits.  Not long after pitting I had Marty and GB come up behind me.  Didn't see blue flags but was wondering who it was.  Only when Marty commented about passing me I realised and on the next straight held 75% throttle to let them buy however on arriving at the chicane GB swept straight across to the kerb cutting me off, spinning me on to the grass.  Anyhow pushed on and in the second half had a good battle with Joe swapping places but with half a lap to go I ran a touch wide and he was through.

Warping:  Difficult issue this one.... I always have 17-19 ping (Optus Optical fibre),  I have a new GTX970, 8gb rar, win64 pro, but I fear my processor may be the weak link as it is a I5 760 2.8hz (4cpu's).  I have been running low graphic settings on race night so the track looks pretty crap but still getting moments of warping.

I also find that the timing or lag is significantly better without the Python stuff. You cannot see or really feel the difference except that you go from struggling to handle the car especially when braking to being able to catch slides and feel brake lockup. This is AC's strength where what you see on the screen exactly matches the feel through the wheel and pedals. If that timing is out even a bit it makes the cars more difficult to drive.

Look in the Apps/Python folder. Those are the Python ones. I am not sure about the Kunos apps.
Title: Re: S7R8: Donington Park GP Post-Race Chat
Post by: Wally on July 15, 2015, 01:51:12 PM
Are we talking stuttering or warping though, in regards to Python apps? Stuttering I could believe, being client-side, but warping? You'd think that would be due to packet loss or something network related.

It's worth an experiment though. For the trial races, we could turn PLP off as well.
Title: Re: S7R8: Donington Park GP Post-Race Chat
Post by: Joe on July 15, 2015, 01:53:17 PM
I assume RSR and pTracker is sending/reading data, but would be surprised if it was enough to cause warping. Happy to turn off all apps except Helicorsa as I'm too reliant on it  ;D
Title: Re: S7R8: Donington Park GP Post-Race Chat
Post by: Gratulin on July 15, 2015, 02:53:53 PM
It is only a theory but think stutters are local cpu related and warping is timing related. Timing related issues could be caused by many things - local PC timing issue, network timing and server timing. So my surmise is that the Python code could be causing timing issues for the AC core network code on the client. Python is a huge resource hit given that it is scripting and lots of calls going on. Everyone is using a tire app, a timing/leaderboard app and Helicorsa. That's a lot of Python code being executed every millisecond.

This is all just supposition on my part but worth a try if people are interested. Only need to uncheck the apps in the launcher General settings.

Wally, PLP could be retained.

Generally an erratic night for me, after only having 1/2 an hours practice prior to qually.
My race was filled with small errors and one major one, hitting a wall and doing considerable damage.
The worst part was getting out of the cockpit afterwards, with locked up and aching knees (took about 10mins before I could walk again). :-[

Thanks to Bacchulum for giving me a smooth driver to follow in the last 10 or so laps. I wouldn't have kept my concentration without his car to focus on.
It was a good battle but I didn't think I was that smooth, lots of tiny errors towards the end there, mainly due to your pressure. 8)

Stracker isnt on the race server so ptracker is not sending anything. Its just using the data the server is already sending you.

If anyone has unstable fps and big drops at times this can cause issues but anyone with rock solid performance running any apps shouldnt have any effect.

Its possible ptracker on a server with stracker could cause lag as it sends and receives more data from the server.

For me my fps is capped and never drops a frame the same in sp or a full grid of mp or even ai. So for me I dont see how the apps I run can cause any issues for me.

The only apps I run on leaague nites are ptracker, helicorsa and sometimes rsr. Anyone having issues try and disable and uninstall all then bring them back with for the latest versions 1 at a time and monitor your game fps.
Title: S7R8: Donington Park GP Post-Race Chat
Post by: Gratulin on July 15, 2015, 07:00:23 PM
The point I am trying to make is that with the Python apps adding a few thousand lines of code between each AC line of code the AC timing may be getting screwed even on an otherwise excellent performance PC. Nothing to do with fps or network performance. The Python apps are the weakest architectural part of AC.
Title: Re: S7R8: Donington Park GP Post-Race Chat
Post by: marty on July 16, 2015, 12:25:11 AM
That is true but only if they are causing performance issue in some way, if there is no negative impact to them and they arent filling your ac logfile with errors then they should not be a problem.

On my pub server I had noticed a bit more warp lately but all I did was disable stracker, this clearly has a negative impact on a server when its running. With it off there were nowhere near as many issues but still one or 2 people with some warps mostly caused by an obvious issue on their end. For me I still ran all my apps including ptracker for live timing etc but I will likely keep ptracker off on all servers other then the XGN practice server and my pub password qualy server.

I removed all apps last night and jumped on Marty's server and then ran a race on my own PC with 16 AI.  I also ran with graphics pretty much maxed out (normally have to run the opposite).  Result, Marty's server was pretty smooth, didnt see any obvious lag (60fps on triples).  AI race I was getting the 99% CPU warning and not quite as many fps.
So bearing in mind I had the graphics cranked up there was definately an improvement in that small test. . . more to be done though!
Title: Re: S7R8: Donington Park GP Post-Race Chat
Post by: marty on July 16, 2015, 12:13:40 PM
Which apps do you normally run freezer, also by the time you joined there were mostly higher pings left so others wouldnt appear as smooth. I didnt see your car warp at all and your ping was at its usual 17.

One app thats known for causing issues is ov1 so beat to avoid this. Its good to test out 1 app at a time to see which one may be causing problems.

The next few tuesdays are fun runs so it would be a good time for those that tend to get warps to try a few things. We will also get v1.2 in that time with some server and mo changes so things could change a bit.

Also do you ever get the cpu warning in a large field mo race? That always had issues with time sync for people that got it and it would cause constant warps so thats 1 thing you should try and avoid if possible.

I had folders for Ferito Live Traker, Helicorsa, Mini Gear, OV1 Info, Ptracker, RSRLiveTime, StatsBarPlus, Tyretemp however they weren't all activated in the menu.
Never get the CPU warning in online races just with AI on my PC.
Well have to swap the apps back in one at a time to test, but first impressions is that it was an improvement.
