Final fantasy XV crash

Support Game Compatibility

Hello,
so I don’t know if this is driver 497.07/496.xx issue, or general denuvo x special K mischiefery, but i just cannot play this game with special K. It just crashes randomly from 10s - 5 mins in gameplay (with MGSV alert sound :smiley: ) and there is nvidia driver file in exception log ? … i dont quite get whats going on.
WIN 11, 2070S, 3700X, 32GB, HDR - ON, clean install of drivers

Those logs are useless unfortunately. There’s a lot of anti-debug in FFXV, so crash logs don’t help any.

There’s a chance there’s actual relevant info in SpecialK.log / modules.log though.

Sorry for necro, but I ultimately fixed this by disabling AMD virtualisation in BIOS. Nearly every DENUVO game was affected.
