Hi guys, This is my current PC: MB: Asus PRIME Z390-A CPU: i7 9700K RAM: 4 x 8GB CORSAIR Vengeance DDR4 PC 3200 CL16 GPU: Gigabyte Vision RTX 3080 ti 12Gb The GPU is connected to the following monitors: Via DP - 3 x LG 27GN750-B IPS 27" FHD (1080p) 240Hz G-SYNC Compatible in NVidia Surround Via HDMI - 1 x ASUS VP 248 (1080p) 60Hz Before the RTX 3080 ti 12Gb I had a Gigabyte RTX 2080 Super 8Gb. I've been using this setup to play rFactor2 since I built the PC and despite having to lower some video settings, I never had problems with the RTX 2080 Super, even on tracks with a big FPS drop like Le Mans or Daytona at night. Since I installed the 3080ti (and updated the drivers), I started to feel a lot of micro stutters, despite the FPS being high. These micro stutters are also reflected on the FFB of my DD SimCube 2 Pro, which makes the whole gaming experience very unpleasant, so it's not playable. I've tested it with a lot of other games (including AAA shooters) and I didn't had any problems. Quite the opposite: even with all the video settings on Ultra I have a very smooth gameplay with FPS above 100, with the following games: Race Room, ACC, Wreckfest and Dirt 2.0 Battlefield 1 and Battlefield 5 When using Afterburner, I noticed that in all these games, the utilization of the 8 CPU cores is more or less uniform, almost never reaching 100% in any one of the 8 cores. The same no longer happens in rFactor 2, Kart Kraft and Automobilista 2, where 2 CPU cores are always at 100% and the rest are used in a very randomly way but not as much. I've already tested the CPU with Intel's own utility and everything is ok with it. I also did the same to the GPU and everything is ok too. Is the RTX 3080 ti so powerful that it creates a bottleneck far too big for 2 cores in a way that the i7 can not handle rFactor2?... What can I do to “lighten” the load on the 2 cores or distribute the “load” on the others via Windows? I need help because I can't understand what happened with the new GPU and I really want to play rFactor2 again. Obviously lowering video settings is out of the question, otherwise I wouldn't have bought the RTX 3080 ti. If the solution is to buy another CPU, so be it… although it doesn't make much sense to me. Thanks in advance.
