Mouse lag with 4k monitor

coolcommando54 · February 9, 2020

Recently got a cheap 4k monitor (Samsung U28E590D) and I'm loving it but I'm getting some weird issues with my mouse in particular. On my desktop, when I move my mouse from rest it doesn't highlight any shortcuts for a few seconds then after those few seconds will start highlighting shortcuts after a second or so. Usually this alone wouldn't bother me, but I'm getting issues similar in games as well. When I move my mouse, the game stutters for a few seconds then I can freely move my mouse again with no stutter.

I have a Ryzen 2600, gtx 1080 and 16gb ram, none of which are maxing out.

I do however have a logitech g402, which I've heard can cause issues but I uninstalled the logitech software which didn't seem to help.

Monitor is running 60hz on a displayport and I've tried several slots on my gpu. Any advice?

Get HWiNFO and look what your CPU and GPU temperatures and frequencies are. I had similar problems when my CPU were throttling due to too low power limit after UEFI update.

Yeah, looks like my CPU is throttling actually. Temps are low still but I hadn't noticed the frequencies. What would you suggest?

On the contrary, i see that current frequency are 3.9GHz which is fine but i don't see temperatures but since frequency is fine it shouldn't matter, at least with CPU ... Did you enable Ryzen balanced power plan ? Check GPU temperature too, when you launch HWiNFO there should be sensors mode, there should be GPU section.

25C on my cpu, 34C on gpu. Surely 3.861GHz is too high for idle? Max boost is 3.9GHz
