I've just finished building a system with a 4090 and the performance is incredible but there seems to be only one issue i've noticed and that is micro stutters/fps dips.
it's very noticeable in Overwatch 2 and i can see it in league of legends.
i have 2 systems which i will post the specs below this because this is important for you to know the testing i've already done:
New system
Old System
I was having the issue in the new system so here is what i did:
So whats confusing me is that the 4090 worked well on the 9900k system, aside from being bottlenecked by the processor, resulting in lower FPS while the 3090 worked well on the 13900k. No issues, no stutters. But for some reason, when pairing my 13900k with the 4090, i notice these stutters.
I also noticed that every time there was a stutter, there was a dip shown in task manager for the GPU. here is a screenshot:
i wonder if it's the PSU in general, but the 3090 was pulling like 350w with no stutters and the 4090 was pulling around that up to 400ish so its not that much of a difference.
Maybe there is a windows issue with my build right now? maybe it is drivers? idk.
would really appreciate any help with this. everything seems to be working fine except for this stutter.

I was having the issue in the new system so here is what i did:
- Took out the 4090 and put it in the 9900k system. no stutters.
- Took the 3090 and put it in the 13900k system. no stutters.
- Put the 4090 back in the new system and tried the adapter that came with the GPU and also tried the 600w cable that came with the MSI PSU. Still stuttering.
- rolled back driver. still stuttering.
- reinstalled driver. still stuttering.
- verified game cache/scanning, uninstalled/reinstalled games. still stuttering.
- tried v sync on/off, gsync on/off, nvidia boost on/off, reduced buffering/triple buffering on/off. still stuttering.
- tried low settings/max settings. still stuttering.
- Unlocked FPS and locked fps 144/240. still stuttering.
