Hello. I need some help with The Witcher 3 and RivaTuner. Even if RivaTuner makes the game's frame timings very stable, I still have some weird stutters related to the program, without it the game seems to run with less stutter, but I get CPU usage spikes, with RivaTuner I don't. Also please note that I get perfect frame time with Windows 10 full screen optimizations but with random 100% CPU spikes at areas of the game with lots of NPCs and that creates fps drops. Right now I am playing the game on a 75 Hz mode with nVidia half v-sync refresh rate at 37.5 fps, this way I get way smoother motion than 60 Hz with half sync at 30 fps and can crank everything to Ultra on the game. I just need some help with RivaTuner's config. I am playing the game on an i5 4590 CPU, a GTX 1060, 8GB of RAM, the game runs on an SSD so I don't think the RivaTuner is related to that. Windows 10 1803 build. What I get are drops that go like: 37.5 fps, 37.3, 37.2, 37.4 and so on, its rare, but when it happens, its annoying. Sometimes also seems like RivaTuner creates random fps drops for no reason, 2 or 4 frames. My Witcher 3 .cfg looks like this: [Framerate] LimitDenominator=1000 Limit=37498 [Hooking] EnableHooking=1 EnableFloatingInjectionAddress=0 EnableDynamicOffsetDetection=0 HookLoadLibrary=0 HookDirectDraw=0 HookDirect3D8=1 HookDirect3D9=1 HookDirect3DSwapChain9Present=1 HookDXGI=1 HookDirect3D12=1 HookOpenGL=1 HookVulkan=1 InjectionDelay=15000 Is there anything that can be tweaked so RivaTuner stops stutering the game?
