Plutonium

bojlermontaz Vsync and FOV settings were already at those values. As for the first two points, you just repeated what I already said I knew and did in the opening post. Is that an AI-generated response? Because it sures does feel like one.

asunaqq Still didn't do anything, even when changing those settings through the console. I've also tried IW4x and it has the exact same problem. T4 and T5 have a "raw_input" which does work, but it's nowhere to be found on T6 (and IW5 for that matter, not sure what's different about it that I don't have problems over there).

asunaqq Didn't work. Besides, doesn't Plutonium use its own settings separate from the base game?

From what I could test, IW5 seems to force mouse raw input, but T6 doesn't. cl_mouseaccel works to increase acceleration in both games, but setting it to 0 doesn't disable it in T6. I'm aware about the pointer precision setting in Windows, I'm just wondering if there's a way to not have to disable it every time I want to play T6.
