Hi guys! Here is a picture about my GPU and CPU all cores usage: This is the official GTE car on the official Virginia Circuit. I have an AMD Ryzen 5 1600 and a RTX2060. As you can see CPU3 does a lots of work, and I think thats why my gpu usage is very low. But I'm a bit frustrated that some other cores on 0-5%. I tried the controller.json tricks: - Use Thread to true - Use Additional Hardware Features to false My experience with the "Use Thread" was this: - When "Use thread" was on default (false), CPU9 was on 80-90% all the time, sometimes 100% - When I set "Use Thread" to true, the CPU9 usage was transferred to CPU3, so that didn't helped much. When I drive alone usually I have GPU usage 97-98%, what is totally okay, but when I start a race with AI cars, my fps drops down to 50-60 and I see that my GPU usage is at 60-70%. So my CPU holds back my GPU when there are other cars around me. And this is what I expreience in multiplayer too. I have 2 question: 1. Is it normal what I experience? 2. If yes, rFactor 2 will be optimized to use more cores in the future? Are they planning some kind of multicore optimisation after releasing new user interface? Or I have to buy a new CPU if I want to use the power of my GPU? Thanks, P.
