I appreciate the forum and any attempts at helping. Here’s what I have:
RX 6900 XT Sapphire Toxic 16gb (2020/21)
BIOS: 020.002.000.049.000000
AMD Driver 28.6.1
*will provide more specs as needed

I’ve had the card for a few months, playing mostly Black Ops 7, and a few other steam games with no issues. The flashing orbes first showed up in the No Rest for Wicked early access. I assumed it was the game but then discovered the same orbes, only yellow in Valheim, which i’ve played many hours with a previous card. I thought maybe it was a Unity engine problem. Then I played Modern Warefare 4 beta and to my dismay they showed up after playing for about 30 minutes. Looked different but the same random blinking and shapes. Strangely I’ve played black ops 7 for months with no issues as well as half a dozon other games. This seems to be a rare problem.
Here’s what I’ve tried so far:
- I tuned the GPU frequency down to 1850mhz. This fixed MW4. I played several hours with no artifacts. However the tweak didn’t make any difference in Valheim or No Rest.
- Tested VRAM with OCCT and memtest_vulkan. Both passed
- Did a 3d adaptive test in OCCT and it generated 1000’s of errors once the card got past 40% utilization
- Did a power test in OCCT and it generated errors then crashed the pc and restarted (no BSOD). Same test did not crash after tweaking down to 1850mhz.
- Rolled back driver to March of this year. Didn’t help
- Reduced in Adrenalin power limit to -10
- Tried countless graphic and display options in-game including forcing DX11/DX12
- Turned HDR off
- Different monitor and cable
- Reseating GPU and power cables
- Temperatures have been great throughout the testing
The only thing left that was suggested by the game dev and steam users is to open everything up, check connectors, clean, possible PSU replacement, card’s thermal paste and heat pads, possible BIOS update. I hoping someone familiar with this specific issue has some pointers. Thank you..
