Hi DJKustoms,
Let me try to help you as well as I can. My system has similar specs, architecture wise. So we should have the same instability issues.
Here are my specs:
MSI X470 Gaming Pro
AMD Ryzen 7 5800X
Nvidia GeForce RTX 3070
Corsair Vengeance Pro RGB 2x8GB
Issue 1: Personally I got rid of the DXVK .dll since it caused major instability for me as well. Much like the crashes you posted a video about. I now use the Alt+Tab method, the video you linked about that was mine.
Some tips to make the Alt+Tab trick more reliable to use:
I have grown to open the map right after launching and loading into the game. So when it does crash, it's not during actual gameplay.
Sometimes the trick does not work, but I have noticed that once you got it working once after launching, you can get it every time during that session.
I noticed it works better when the settings are at a highest quality, thus more demanding.
It probably takes longer for the game to load back in like that, granting you more time to zoom out in the black window.
Turning refresh rate from 60 Hz to 59 Hz seems to help with success rate, though this might be placebo.
I'm using a ReShade with my TDU2. This might also put extra load when loading back into the game, since it has to load the preset.
The biggest pro for using the Alt+Tab trick for me, it that you know when the game might crash. This way you can prepare, and save before if needed. With the DXVK my game could just crash at the most random moment, like your videos show as well.
Issue 2: Sound and look like DXVK issues. Are you still using it here?
Issue 3: Could also be related to DXVK.
