My specs: Ryzen 5900x @4.6Ghz 32GB 3600Mhz CL16 ram RTX 2070 I have tried a whole slew of things and I can't get my computer to stop doing this. It does this in the menu before I load a track and during and after and while I race; all the time. Below is a screenshot of my CPU usage. https://imgur.com/a/gYYzYos This program, Process Explorer, tells you what is using the most percentage of your CPU by hovering your mouse over the graph and at any point in those 4 threads the most usage will be rfactor 2.exe. I do the tweaks listed in Risto Kappet's thread: https://forum.studio-397.com/index....rmance-guide-on-how-to-prevent-low-fps.61265/ Here is a short list of some stuff I've tried that didn't work: -Tried all different sync settings in launch graphics settings -Selected GPU in graphics settings -Set "use thread" to true and false -Launched in single screen or triple screen -Disabled all plugins -Deleted cbash and shaders content -Uninstalled all non-S397 content -Tried factory settings on BIOS -Updated BIOS and drivers -Tried different AMD overclocking configurations -Updated Windows -Updated nvidia drivers -Tried disabling fullscreen optimizations on rfactor 2.exe -Disabled anti-malware, windows defender -Created exceptions in firewall -Turned hyperthreading off -Disconnected wheel and pedals -Switched audio device to monitor and disabled Realtek audio device in BIOS -Tried Game Mode on and off -Updated AMD Chipset Drivers -Tried setting "autonomous render thread" to false -Tried deleting the Userdata folder and letting rF2 replace it What causes these high CPU usage spikes? I can't be the only person experiencing this.
Maybe in player.json, try setting "UI autonomous renderer thread" to "false". And try with a clean user profile (rename the UserData folder)
