What driver version? I had to roll back to 20.11.2, the newest drivers are causing problems.

Try the specific 21.11.2 drivers if not already on them. In the Radeon control panel, click the City Of Heroes icon and make sure you are not using any Radeon specific optimizations such as Anti-lag, Chill, Sharpening, enhanced sync, etc. Disable them all only for COH and see if that helps, being an older game some of those settings may be causing the crashes. Try running memtest just to make sure your ram isnt throwing errors. https://www.techpowerup.com/memtest64/ Make sure your chipset drivers are updated, along with BIOS.

What is your video card? I was having some serious crashes on my Win10 AMD RX580, rolling back to drivers 20.11.2 stabilized the system again.

Hey all, just a heads up regarding a possible AMD driver issue and COH Homecoming. I'm running Windows 10, fully updated, Ryzen 5 3600 w/ RX580 Red Dragon. Stock clocks, no Ryzen master/bios mods. I have been playing COH just fine with all graphics settings maxed. I had to step back a bit due to work and didnt play much, next time I tried to launch the game it gave me fits, just outright crashing with no crash reporter except the ATI Wattman crash submission tool as the crash was bad, locked up the system. I updated to the most recent beta drivers and same brutal system halting crash with ATI Wattman warning that default profile was restored. I was thinking of what changed on the system since the last time I played, and all I thought was the video driver. I rolled back to 20.11.2 and everything is fine again. If having issues, try that version of the driver. In the meantime, the two times I triggered the ATI Wattman crash report, I did complete each report as best as I could, hopefully ATI takes notice before everyone is crashing.

Windows 10, relatively updated, launcher shows User policy, click accept and nothing. Tried running normally and as administrator. I can provide a dxdiag if requested.
