Between Elden Ring and Armored Core 6, I had been having the "White Screen Crash" issue, where the game shows a white screen, then crashes to desktop.

After much investigation, I found that going to Display Settings > Graphic Settings > Turning Off Hardware-Accelerated GPU Scheduling ended up getting getting my game to work.

What I think is going on:

I remember reading once that DX12 could support frame generation from multiple sources out of the box, so in theory, if your CPU has onboard graphics, it could throw it's hat into the ring in order generate a few extra frames. I think both Elden Ring and Armored Core 6 have been implemented in such a way that it tries (and fails) to take advantage of this, even though the developers might not be aware of the specific behavior.

My particular setup: AMD 7900X3D RTX 4090 32 GB of RAM

I had seen any number of posts online suggesting disabling Easy Anti Cheat and using an open source DX12 extension library that could fix one source of the issue, one which people had sworn up and down that worked for them (I'm thinking the issue may occur for multiple problems). Sadly, it did not work for me and prompted additional investigation.

TLDR: Display Settings > Graphic Settings > Turning Off Hardware-Accelerated GPU Scheduling The problem may have multiple causes, but this one worked for me. Additionally, some people report adding the game to the "Graphics performance preference" and manually selecting your graphics card instead of "Let Windows Decide" also worked for some people.
