Mate it's a complete bargain currently, $30 on steam: (daily sale, so jump on quick)

But keep in mind it's hotlapping only currently.  It looks AI is in the pipeline and multiplayer will probably come last.

There are a few combos that are fairly empty...I was able to get up to decent positions in no time there :)

Nothing to be scared of mate, it's a long standing legit, correct business.
Don't ask me how, but it works. :)

Interestingly, I've updated the driver to the latest whql (331) and the flickering is now contained to certain places, like roadside boards, whereas previously the car cockpit was mostly flickering.   Still not 'good' just 'acceptably crap' ;)

I've tried that and didn't work - but I may need the update the gfx driver.  When I've time...

Thanks anyway!

2152
I've seen worse...:D

But on a serious level; did you have any problems, or you simply found the temps too high?

Mate, you seem to suffer from the same problem.  You've the performance of a single 670 - see Dave's results above. Comparable.
I've since posted on the AC forums, but got merged with an old thread which I don't fully understand, they talk about setting bits - dunno where or how, though. Not yet, anyway.

This is the thread if you guys are interested:
http://www.assettocorsa.net/forum/index.php?threads/sli-how-to-get-the-best-performance.1416/


Ah, I've now read the thread more carefully, and here's how one changes things:
Quote
I'm using the latest version of NVIDIA Inspector (you can check for updates on the program itself). To edit AC profile, click on the "toolbox" icon next to your driver version, look for "Assetto Corsa" in the drop down menu in the top left, check that acs.exe is being considered in this profile and then change SLI Compatibility bits (DX1x) from 0x00000000 to 0x080210F5. Press Apply in the top right and you're good to go. You'll know it's working if when launching the game you get mad flickering from HDR for the first 10 seconds or so (while the camera spins around the car as it sits on the track).

but as he wrote it gets really flickery - altho the performance pretty much doubles, that's true :)

These are the values one can try:
0x000040F5 
0x080210F5
0x000110FB
0x080202F5

the last one does not work for at all, for me, the rest gives me the flickers.  I'll just wait till it's fixed. :)

It does, Dave, thanks.  Altho you were running at mugello, that may skew the results a bit, it's still very comparable.  It seems I'm almost getting a single-GPU performance, even though both are being used (watched it in MSI afterburner)
I think it's time to post on the official forums to see if they can help me get it right...


Thank you Wally, yeah it seems we've an SLI optimisation issue here or somesuch.

ps; the bottleneck; not sure if it would come out in AC as of now.  Maybe some other games are more demanding...I think you've got plenty of fps for now :)

Wally, any chance you can run a test with these exact settings?
If you don't mind I'd really like to get to the bottom of this.

(fxaa is ON in the nvidia control panel this time)

These settings give me a solid 60-65 fps in 5760x1200
(the reflections seem to be a fairly big hog of performance when upped!)

hm...ok so you run fsaa instead of AA - that might be something worth looking at.
Funny thing is that I've read around that the 750 is barely enough to drive a 670 to its full capacity. If that is true, you're definitely bottlenecking the 780 - and still getting much better performance...damn! :)

Edit: running fxaa (as it's called in the nvidia panel - this is the fsaa I reckon) I get 70-80 fps in 4800x1200.  And around 60-70 in 5760x1200.


I really wish you were living closer, I'd definitely like to give it a try chucking that card into my computer...

I'm pretty sure it'd be fullscreen on where it should work, because otherwise the desktop takes over...but I'll test it.
Edit: tested. barely a difference.

Then this:
I've reduced the resolution to 4800x1200 (5.7mp) leaving everything the same.   60fps.  That's against the 80-90 of the single 780 at 6.3mp!   In the meantime I was logging via msi afterburner, and the cpu usage was pretty much at max on both cards, memory at ~1850 out of the 2048 (MB).  I've tried both full screen and windowed, barely a difference as I said (windowed was down 5fps or so)...

There is something fishy here I reckon... :)

Can you post your full pc specs? mine are:
ASUS p8z77-V Deluxe
Intel i5-3570k
Corsair Vengeance 2x8GB

2x GXT670 (Gigabyte)
Sound Blaster recon3D

SilverStone Fortress FT02B-W
Antec 850W Signature

Without altering my other settings (most around medium) my 2x670's work better with HDR on rather than off.
That is mighty surprising, mate.  HDR does require extra from the cards...

I've tried to set everything to max, no HDR, no blur - again, as I can't stand it, hehe - but I've left the reflection stuff on the default.
This gives me about 45-55fps (looking at the system gadget top value - hope that's the fps)
with HDR on, otherwise all the same it drops to 35-40

I reckon SLI optimisations aren't on....

There's one widget something like rendering stats...I think the topmost value is the fps. (output these by moving your mouse to the right-edge of the screen and selecting which one)
If not, then I'm looking at something utterly wrong :)
