Hello everyone, i've been having this problem for some time now (september or october 2017), was hoping the new performance patch would fix this, but it didn't. So i'm trying to make this first post as detailed as possible. Maybe someone else hat this problem and knows a solution? What happens: When ever i drive in rF2 with other cars on the track on- or offline in vr i get really bad stuttering, sometimes freezes (up to a second, mostly about 0.1 or 0.2 sec) which basically destroyed online racing for me. Things i've already tried: - reducing graphical options (framerate is overall ok, with the new patch even a lot better) - increasing cpu priority - using the "use thread" option in the controller.cfg - updating drivers for sound, gpu, steering wheel etc. and bios, even tried some older drivers - overclocking my ram - cursing a lot - disabling CSW 2.5 P1 LEDs - putting the game on HDD and SSD - *edit Oct. 2018* reinstalled Windows 10 - *edit Oct. 2018* connected the pedals directly to the wheel and via USB to the pc My system (let me know if i forgot something important): - Windows 10 - Ryzen 1600x - Asus Prime B350 Plus mainboard - GTX 1070 Super Jetstream - 16 GB DDR4 3200 MHz (running at 2800 MHz because mainboard limitations) - 600W BeQuiet Straight Power psu - Fanatec CSW 2.5 with P1 wheel, CSR Elite pedals and Thrustmaster TH8A shifter - Oculus Rift More i've tried to find out what's causing the problem: I also tried to gather some information what might be the cause. First though was other applications might steal some CPU/GPU/RAM, but that doesn't seem to be the case. This also happens in any other game (vr or not vr). I can drive without any problems online and offline with lots of cars in Assetto Corsa, RaceRoom, Automobilista and Project CARS 2. With higher settings the framerate might drop, but i don't get those short freezes/stutters i get in rF2. Data i've gathered: I have recorded some videos, used the ingame performance monitoring to log a lap and made some videos that show the problems + some additional information about what's going on with the CPU, Ram and CPU: Video 1 (CPU usage): The first video shows mainly my CPU usage in the Task Manager and Process Lasso. At about 0:55 is the largest stutter/freeze. When this happens online my car just disappears and reappears at the same location after the freeze is over. You can see it in this video, watch the blue car disappear and reappear in the mirror, that was my car) Video 2 (GPU usage): The second video stutters almost all the time (it's not just the recording, it's running like that on my system), but doesn't have any extrem freezes like in the previous video). It shows what the GPU is doing in the Task Manager and GPU-Z (watch the gpu spikes in the taskmanager when the stutter happens): In case anyone is interested i also recorded a video without the games vr support (but i had to use the vr headset and Virtual Desktop because i can't see my monitor from my racing seat): The video is running smooth. Sorry for this wall of text, but i wanted to answer as many questions as possible before someone's asking I also uploaded a performance log from one of the stuttery laps. Hope someone has some ideas what might be the cause and what else i can try. rF2 is in terms of driving my favorite simulation, but especially online it is almost unplayable right now and not fair towards other drivers because those freezes might cause bad crashes. If you need some additional information just ask (answer could take a few hours).
