A problem I especially noticed in Ubisoft games. Even if you use the graphics settings at the DSR 4K peak, the CPU usage is at a high level. I think this problem arises because you can not optimize the game engine well. I would like to ask. If you are optimizing all the Ubisoft games including Rainbow Six Siege, I'm delighted. Optimization needs to be constantly updated, especially in multi-player games.

Please see if limiting the frame rate using the limited from our 100% CPU blog post helps.
