Hello everyone!, I have an AMD 5900x and a RTX 4090. And unlike what happens to me in other simulators, I have better performance with SteamVR than with OpenXR in Rfactor2, with SteamVR my CPU frametime is about 10-15% lower than with OpenXR. Does something similar happen to anyone?
I've also noticed that, unbelievable as it sounds, the 5900x may be bottlenecking the 4090. Thinking of upgrading to the upcoming 7900X3D...
I would rather wait for single chiplet x3d model than buy the 7900x3d. the multi chiplet models have infinity fabric between the cores, and only one chiplet has the v-cache (the 3d part).
And even tough AMD's idea of this is to have the cpu (and windows OS) know
not to use the other chiplet (that doesn't have the v-cache)
for gaming.
THAT, is a big ask for microsoft as the scheduling of the cores lands on them. Trusting MS to guarantee that your HW works as it should is a gamble to say the least. I would not do that, trust windows that much that is.
AND since single chiplet models are gonna be enough for any gaming situation, waiting for the successor for the 5800x3d from the 7K lineup, saves you from the gamble, and will be fast af.
Also, your 5900x being a bottleneck might sound hard to believe/imagine, but that is exactly what it is, IN THIS GAME.
Me and fellow VR user did test our cpus against each other,
on same track with same cars, AND the
CPU frametimes were higher on the 5950x (his) vs 10700K (mine), even when he had less visible cars, and much lower resolution. He got more dropped frames too.
My 10700K is overclocked to 5.2GHz cpu, 4.8GHz cache, and ram overclocked and tuned to 4200 16-19-19-40, with floored subtimings.
The ram OC+tuning, or more particularly, the latency gains from it, (38.7ns) i think gives my i7 quite the boost, but the
multichiplet design of the 5950x is clearly the thing holding it back
for this game in particular, as the 5950x simply destroys my i7 in
any cpu benchmark, as it does in most (if not all) game benchmarks too.
Here are both videos of the cpu battle at Portland:
Big thanks for Emperor, for doing this with me!
At least we got some solid data of the cpu performance, intel vs AMD
in rF2.
No one has agreed to proof the capability of the 5800x3d for rf2 VR as of yet, but much talk about it being good for this game goes around.
P.S. This was done in steam vr, for the sake of using FPS VR overlay.
I use Open XR nowdays, and that same scenario runs much better on it, ie. higher resolution, without any upsampling (for this test we had about same amount of FSR upsampling, roughly 250x250 pxls per eye higher than render resolution).
