I have just upgraded to two evga 3090 ftw3 cards and the debug build of Linked GPU sample crashes with same exception after 1 second of execution every time! Call stack:-

The D3D12LinkedGpusAffinity runs for a bit longer but crashes in similar fashion.

Release build of same code runs fine.
@Phil-Lewin I've since made stable Linked-GPU support. The example is missing I think is missing some resource lock before or after present but its been so long I can't remember. Frankly the example is a fragmented mess.
Think there is a race condition in the Linked GPU example. If I breakpoint on line 191 and increase the resolution to 1080p etc then continue to run I'll sometime hit an access violation.

Also when I run this test on a Crossfire R9 280x setup it blue-screens windows.
