I try to run rFactor 2 on my Reverb G2/3080/9700K@5ghz/16GB 3600 but this seem to be impossible for me. I tried every single tweak/setting that I could find on this forum and reddit. But it's impossible for me to get a 90FPS stable frame rate. Even with an average 40% GPU load and even less CPU load the game keeps having huge framedrops which makes it unplayable. The strange thing is, for 1 our of 10 times of the testing I can drive a few laps without a single framedrop but 9 out of 10 times there are huge "purple lag spikes" on the GPU part (tested with FPSvr and without). This in the same gaming session, just after I restart the race(when I thought that it was "fixed"); it happens again. I tried the latest nVidia driver but also old drivers like version 456.71. I tried all possible settings/all player.json tweaks/pp off/low resolution/no msaa/cache delete etc. etc., but it even happens with everything on LOW and with very low resolution in steam (even with 30% steam resolution I keep getting framedrops). This while more demanding titles like ACC/AMS2 give 90FPS constant without a single framedrop on the same setup in VR. Edit: I want to add that the frametimes are VERY low, ~4-5-6ms not higher then that but the lag spikes keep coming.
