Random white pixels

[Chris85]

Hi there,

recently, I've noticed that when white objects are animated against black backgrounds, a few white pixels sometimes appear near the white objects and disappear immediately. So far, I've noticed this in the loading screens of Call of Duty and Star Wars Outlaws. Usually, it's about 5-6 pixels that appear white somewhere near the bottom edge of the screen and are visible for just a few fractions of a second. I ran dxdiag, but it didn't show any errors. Additionally, benchmarks all show stable and fairly good results. Does anyone have an idea what it could be? I'm using a 13900k with an RTX 4090. My monitor is a 34GN850-B with 144Hz and VRR or G-Sync compatibility and HDR enabled.

Cheers!

Edit 1: I changed display port cables, nothing changed. The pixel also appear in recordings. So it seems to be something with the card or the drivers.

Edit 2: After having the drivers reinstalled no change.

Gpu or games at this rate, could be a nv setting causing the artifacts even, play some more games and see if it happens.

Could be the monitor and nothing to do with the PC. Try at different Hz. 100hz 144hz. Is it overclocked? Maybe set it back to 144Hz.

The issue can be recorded via shadowplay so it has nothing to do with the monitor or the cable.

You might try another gpu, or contact the game maker or nvidia

Well, my experience is that most users in this forum have far more experience in technical things than the typical 1st level support of nvidia...

It could very well be a driver or game issue, at worst your gpu being the problem.

You already tried a driver and it didn't change anything.

This may be hardware prolem.

Did you tried tests/benchmarks that not just renders but verifies gpu operation correctnes?

Hardware problems related to shader execution often can be found with GL-based tests in MSI Kombustor utility with "artefact scanner enabled", normally its artefact count should be 0/0 after 5 minutes run.

VRAM problems can be detected by https://github.com/GpuZelenograd/memtest_vulkan utility, it should pass 5-minutes test without errors.

I ran both tests for like 5 minutes and everything was fine. No artifacts and everything passed. So it must be a thing with those games or maybe with my cpu? I have an 13900k. After I installed the latest microcode update yesterday it feels like the white pixels got less.

But a huge thank you for the tip with those test programs. Now I know that the card is okay.

Yup games related Id report your findings to the game makers and nvidia.

Today I got a reply from MSI. They say that it could be FPS-Peaks in the loading-cycles

May consider vsync of some sort for now
