GTA 5 Lagging ONLY When Moving Mouse

post #1 of 4
Thread Starter 
Hey guys, pretty much as title says. The game runs butter smooth but the second I move my mouse, FPS plummets making the game seriously unplayable. Here a graph comparing driving around without touching my mouse (red) and the other periodically looking around (blue).



As you can see, it drop as low at 20 fps, though honestly it feels more like 10. As soon as I'm stop the mouse, frame rate goes back to 60.

System specs are 4.2GHz 5820k, 16GB ram, and 1.5GHz gtx 970. All these OC's are tested stable. Temps are upper 50's on the CPU and low 60's on GPU. While I do have triple screens, keeping GTA 5 to one. GPU drivers are up to date, and same issue even with older drivers too. CPU usage is generally pretty low at the times, and GPU with current settings sits mid 60% range, however this also plummets when moving camera.

Things I've tried including reducing settings, removing OC's, trying the other mouse input settings, putting the game on my SSD, and many of those stupid "alt tab out and back in" or "change one setting and put it back" fixes. Nothing seems to work. Any ideas? I'd like to play this game but it's not worth it with this issue. +REP to helpful posts! thumb.gif

Edit: Future people who stumble on this, while I don't think I got it working perfectly, unplugging extra monitors seemed to help a TON with this issue.

"Enabling Direct Input" works for most people, a quick bit of research says.

I have already tried all three modes; windows, raw, and direct all give the same result.

Bump. Have also tried verifying steam files as well as reinstalling the whole game, still not fixed.
