If anyone is experiencing the issue even now, limiting your fps to something your graphics card can handle might fix the issue.
I was experiencing D3D device lost error, repeatedly on my Windows 11, Ryzen7 5800x, RTX 3080, 64GB, Driver 496.13 Machine. Tried all the methods mentioned in all the forums.
Finally setting t.MaxFPS 29, worked for me. Higher values like 59, resulted in the same crash.
Hope it helps.
