I'm not really sure if this is the right subreddit to post this but I need some help. I've recently been very worried about my GPU's (Gigabyte Aorus 3070ti) VRAM health as I've noticed small, inconsistent artifacting only when playing Forza Horizon 5. Example: https://streamable.com/rgcw3c. This is the only game where this artifacting happens. Other games I have is Forza Motorsport, Rocket League, OSU, and Cyberpunk. Artifacting only happens in both Forza Motorsport and Forza Horizon 5.
Using MSI Afterburner, I've always had an undervolt in my GPU of 900mV@1950MHz. Two applications I used to diagnose my GPU are OCCT (VRAM test) and memtest_vulkan. With OCCT, within 3 minutes errors that ranges from 10-30 consistently appears. However with memtest_vulkan, the full test completes without any errors. I've also tried with the default GPU V/F and the results are the same with the two application. I've ruled out overheating as the culprit. Monitoring with HWiNFO64, GPU temperature never exceeds over 70c with a hotspot delta of 10-12c+. Memory junction temperature sits around 70-75c.
What I have tried to fix the issue:
– Uninstalling the GPU drivers with DDU in Safe Mode and installing the latest drivers
– Setting BIOS to default settings
– Cleaning the PCIE connector with isopropyl alcohol
– Checked PCIE cables and PSU cables are connected properly
