    Hey, I've had this problem for a while now, happens in both single screen/VR (I don't have triples)

    So what usually happens is I'm driving on almost full practice server, let's say VEC with up to 80 ppl on server and I have stable 90 FPS with around 4-8ms of GPU frame time according to FPSVR software, CPU frametime stays at around 7ms.

    Then comes race and my fps goes to 30-45 with 15+ms of GPU frametime, CPU frametime stays around 7-10ms. And no, it wasn't just the start of the race where I had that fps, it stayed there for 80% of my VEC stint which was 2hours.

    Also the FPS seems to go smaller everytime theres LMHC near me.

    I'll update this report with trace+log from FPSVR once I get them, for now I only have the perflog.

    AFAIK this happens to most of the people no matter the PC but for clarity there's my system specs: https://www.userbenchmark.com/UserRun/23628790
    rF2 installed on mx300

    I don't use these forums alot so the best way to contact me is on discord: Captain Perkele#1271
    Cheers, Joonas

    I reported this problem in March last year:
    It was eventually resolved for me by performing a complete system re-install. Noted that my issue was definitely a CPU frametime limitation.

    At the time, in response to other other drivers' queries, I stressed that I didn't see a system re-install as being an appropriate response for all that suffered similar race day problems.

    But, for me, after extensive work with hardware, drivers, game settings, installation and options it was the only way to resolve the issue. In the following weeks I would occasionally recreate the problem, even with the clarity of running a bare bones system dedicated solely to rF2 the only way to get back to optimum performance was a complete Windows re-install.

    I have been running rF2 for almost a year with steadily improving performance (a processor upgrade has also helped), the last VEC race saw a return of the problem.

    I mention this as in my experience the issue did not lie within rF2. rF2 suffered from an inconsistency somewhere in my system environment (I started to resent how little control I had over Steam VR making changes to my system, making it very difficult to make comparisons to a stable baseline).

    I hope this helps if this current itteration of the problem, that is affecting far more people, has an indirect cause somewhere in the OS.

    is your power management of the cpu such that it throttles down the cpu when it overheats? Choose Performance setting.

    No it doesn't throttle: When I'm gaming I'm using high performance mode where cpu's min/max state is 100% and it's not that hot anyway to start throttling.
    Also the FPS drop happens immediately after you change session. Not mid session, which indicates it's not overheating issue. Doesn't also really matter if the closest car is next to you or different side of the track, fps stays weak.
