My System Specs are attached, I run a 5070 TI as well.
So about this problem, it's isolated to just Unreal Engine Games. MGS Delta gave me similar errors as well. Fatal Errors and a crash. The game will run for a time before this happens but the crashing is constant.
I lowered settings and capped FPS, Did a clean reinstall of my drivers, Checked Temps on both GPU and CPU and all seem to be nominal. I turned off ray tracing and currently use DLSS. I swapped between -DX11 and -DX12 as well in launcher settings.
I am at my wits end with these errors, and I would like dearly to play this game. I love it so much but i have been in this situation where I cannot without some kind of technical support or patch.
