AMD Radeon Vega 8 Graphics. I might mention that my Windows 11 is the HOME edition and not the PRO.

I run Win 11 Version 24H2, OS Build 26100.4202. Update KB5058411 was installed back on May 15th. I have used VarAC 11.2.0 more than once since then and have had absolutely no problems running it. In fact, I have never had any trouble with any VarAC version after any Windows update. Maybe I'm just lucky? 73 de K9JAJ Jeff
