I know, this has been discussed a few times already, however I still can't really get the max out of my system. I recently got a Ryzen 2700x (No OC, great CPU cooler) 16GB 3200Mhz Ram and a RTX 2080 (No OC) (I know, AMD has a low Single Core Performance) When I am in VR with a big grid, my frames drop significantly, even when I have all settings on low and supersampling off. Here are too example videos of the load on my system. 40 AI run at Silverstone short one lap.(I was not wearing headphones and sitting next to my wheel so ignore the sounds of my driving. ) Run 1: Supersampling: 0 Video: https://streamable.com/h0drt With those settings it ran at 90FPS and had a headroom of 20-30%. As you can see the system is never fully loaded. Alright, why would it, here is enough headroom. Run 2: Supersampling: 1.4 Video: https://streamable.com/q3bwv Here it still ran with 90FPS, however the headroom was between -10% and 5%. So the FPS dropped below 90 several times when something in front of me happened. As you can see from the video, the CPU usage of any of the cores was never really above 85%. What can I do to get the extra 15% of my CPU to be used. I just tried the same settings as in the last run with "Use thread":False and it appears that rfactor uses 5% more of the core then. However, it's still only 90%.
