I Have bought a 6900xt Red Devil and i got major issues with it. My GPU Clock Speed, Vram Clock Speed, Power Consumption and Junction Temperature are dropping at the same moment causing stuttering. In Games like Fortnite or Warzone it keeps stuttering really bad and in Escape from Tarkov there is only a GPU usage of 70%.
I already tried:
-Changed my Mainboard
-Changed my CPU
-Changed my Ram
-Changed my Power Supply
-Changed my Monitor
-Bought a New 6900XT from MSI
- Uninstalled all Drivers with DDU
- Set everything off in Adrenalin Software
- Set V Sync on and off
-Installed new Windows 10
-Tested all my PC Components
-Running games without Adrenaline Software
-Changed in bios to pcie 3
-Changed my Ram Speed
-Changed logs in regedit
Tried like everything and nothing helped. As soon as i put any options on in Adrenaline it gets even worse. Cant find a Solution and i think theres maybe a Problem with the Drivers. Maybe theres someone here who can help me.
Also i forgot my specs.
6900XT Red Devil
1200Watt Asus PSU

RAM Gskill Trident Z 4266mhz @ 3600mhz
Ryzen Cpu 3950x 16 Core

3x samsung M2 SSD
Monitor: LG 38gl950g-b. 3840x1600. 21:9 DP 1.4
My card is just a reference model but I noticed some of the same behavior while playing Destiny 2, but I did manage to sort everything out eventually. The trick for me was to stress the card more and run a 150-200% resolution scale and then set the in game frame limiter to 170 (my monitor is 3440x1440 144hz). This combined with a healthy manual overclock (2800 mhz on core) and everything stabilized quite nicely. From what I can tell there are certain titles that don't play well with higher power AMD cards/processors due to lazy optimization on the developer side.
Use the AMD Bug Reporting Tool if you are ok with data trawl of your machine and report the poor performance to AMD.
Looks like there are a number of people with similar issues.
Do you have any kid of overlays running? I recently started playing an old game that had horrible stuttering, and it turned out to be the Steam overlay causing the problem.
