    Thats no way to tell if you are running the gpu @ 100% in the times the FPS drops bellow 90. But do as you wish, its our loss.

    I haven't tested an Nvidia card in AC, but all things being equal, I guarantee you will be cpu bottlenecked during the 24 car race crashing your 90fps down to 60 or 70.
     
  2. Not in my case, only when i run big AI grids. But when doing what i like most in AC, running nice (street) Rally stages, the GPU is the bottleneck when i put everything to max and 1,5 (Oculus count) SS. Running my CPU with normal 4,7Ghz Turbo

    Yeah its not a problem when alone.

    Look at this one just now: Praga @ Brands Hatch 24 cars

    Notice the last graph (framerate), all the dips it had and the GPU usage dropping when they happen. When it fell to 60fps from 90, my gpu was @ 30% capacity.

    UE4 supports VR by default.
    Something wot I made. And if I can do it...

    I think Kunos are a very talented team. AC is just pretty old considering the hardware we have today.
    If they can manage to separate the CPU rendering pipeline from the CPU physics etc and distribute it across different cores, they will be alright.

    I say this because even though UE4 has good support, its Kunos proprietary tech that needs to allow for what I said above.

    vr in AC is very cpu limited, an online race with 20 cars was guaranteed to be 45 fps for the first lap or 2

    I agree. My i5-4670k was hitting negative headroom (and hovering around 100% in afterburner), but after getting the i7-8700 after my previous mobo died, cpu is now just hovering around 35%, and same gpu now the one hovering around 100%.

    my old i5-3330 was hitting -100 to 150 headroom, just updated to i7-6700 and I'm getting much better perfomance from the same GPU , still tweaking the settings at the moment but I have med/high settings and drops to 45FPS at race start but once the pack spreads out a bit it jumps back to 90FPS.

    What are the cores doing? The 8700 is of course much better but you will find that a couple of cores/threads are maxed and the rest of the 10 threads are doing little.

    Think of it this way. If you have software that heavily uses 2 cores only and you are using a cpu with two cores that cpu reports 100% usage. Now you upgrade to a CPU with 4 cores but the software hasn’t changed, it’s still maxing two of the 4 cores, you get no better performance but CPU usage is now reported at 50%

    Pro Lasso shows they're almost balanced. No core parking too. I'll try again later and take a peak a few times under the HMD.

    Todays software and games should utilize multiple cores well, it is state of the art. I am sure that Kunos is aware of the bottlenecks and will do anything to make sure that the CPU does not limit the game too much, especially when they want like 30 Cars on the track.
    The Unreal Engine itself uses multithreading and they just have to do it for physics and AI. Especially the latter one is great for Multithreading as there is barely any relationship within a frame.

    AC already uses multi-threading for the AI and physics, and @sherpa25 's case proves that, he said his cores are almost balanced, that means AC uses all cores/threads. Before he upgraded his CPU his system was CPU-limited, not able to push the GPU to max, now his system is GPU-limited (reaching 100%), the CPU cannot push faster than the GPU can process...

    I wonder why I always seem to have two cores maxed and the rest lowish. Anyone have any suggestions? Always assumed one was graphics and and one something else AC related.

    Not sure, but have you tried Process Lasso (ie. to ensure there's no core parking, and other options as well as assigning gaming performance, etc). Nonetheless, has it been confirmed how much cores are utilized by AC? Sorry, haven't searched are this.

    No, haven’t tried, just been monitoring with performance monitor. May give it a shot when I have time.

    It would be a great thing to have the possibility to launch ACC in a VR mode or not like PC2 (and that the game save the settings for each).
    And to have a dynamic mirror (ajustable maybe ?).

    An absolute must for VR. Unfortunately the E3 demo still seems to have static cameras. I can only hope it's something they're still working on.
