Hi everyone
i have big problems with my new strix 3090 oc.
My configuration is:
I9 10900K set in stock
Maximus XII Extreme
Custom Loop EK cpu only
32 Gb Ram Gskill Trident Z
ROG Strix 3090 OC
Case Obsidian 1000D
ROG Swift 25 "240hz Gsync monitor

since I mounted the new card I always have micro stuttering in everything:
Benchmark (superposition / Firestrike / Heaven .... etc)
All games (RDR2, AC Origins, Farcry5)
The only game in which it is less frequent is DOOM Eternal.

They are annoying micro stutters that prevent me from playing on a 2000 Euro card!
When this happens the use of the GPU goes from 95% to 70% and then goes up again (see the attached photo).



I tried to:
Clean formatting of windows 10 without any kind of monitoring software
Detached all HUBs and RGB Supports
Tried several types of nvidia drivers.
Enabled / Disabled Gsync
Changed Display Port Cable

The card appears to run smoothly in both stock and oc with excellent benchmark scores.
No errors or crashes or reboots.
I don't know what to do anymore ... I'm desperate ... such a powerful and expensive card but you can't play !!

GPU temperatures are normal (max 68 degrees) and CPU temperatures are also normal (max 62 degrees)

Could you please help me?
thanks a lot
Francis
