No change here either. But now that you mention it: IIRC SS3 did sometimes lock
up the GPU before

Here is one with VM faults from starting The Talos Principle Public Test, just
up to the main menu:

Sometimes there is also a Packet0 error at the end. Didn't get it while
recording, got it 2/3 times while replaying.
