I am now addicted to racing with VR
and are facing quite a few challenges in doing so. Last Tuesday night was very frustrating when Discord would not function without massive stuttering, I later discovered my CPU was so overloaded it could no run Discord !!! having 23 other cars on the track would not have helped.
My current CPU is a i5 4690k OCed to 4.5 Ghz 4 cores no threads, cost me $200 used, and coupled with a Gigabyte 2080ti.
Through a lot of testing I have found the sweet spot for my Lenovo Explorer VR headset (1440x1440 displays) is to run them at 3200x3200 per eye!!! at this setting the result is close enough to monitor quality
imho, these are the sort of resolutions the 2080 ti excel at.
I now have Content Manager video settings( most stuff turned off or very low) that we allow me to run up to 8 AI cars at 3200x3200 at 90FPS (critical rate for VR) with it seems, most combos of cars and tracks, the immersion is so good you don't seem to miss the missing eye candy.
Using MSI Afterburner I can see my CPU is 100 % utilised and GPU at about 75%. This is with most apps turned off including PTracker.
Now the point of all this is what CPU would I need to get 100% utilisation of my GPU and plenty of CPU headroom to run the Apps I want and what is the limiting factor with FPS with a large number of cars on track, is it CPU or GPU?
The Ryzen 7 3700x is 8 cores plus 8 threads BUT core speed is about the same as the i5 4690k, would threading plus 4 cores make that much difference in my situation, I know Assetto Corsa supports Hyperthreading but not all Simracing programs do.
Would I need to go to an 12 core CPU at a nosebleed price
. I am hoping someone here at XGN can help as this will hopefully be my last PC build

Looking forward to your repies
