In the past, Bethesda DX11 games have been known to perform better on NVIDIA GPUs due to better driver support. However, this may have changed over time. Personally, I had a good experience running Fallout 4 on an AMD RX 6600M at 1080p using the DXVK wrapper.
When it comes to performance, having at least a 6/12 core processor with high IPC (Instructions Per Clock) is essential. In addition, a thoughtful mod configuration and proper INI settings can make a big difference in game performance.
In my case, my laptop with a 5600H CPU and 6600M GPU runs well at 1080p resolution. If you are targeting 4K resolution, I would recommend considering the RTX 3080 because of its strengths in handling 4K compared to AMD's GPU. Of course, having a more powerful GPU is always beneficial, but it can also be more expensive.
Ultimately, finding the right balance between CPU, GPU, modding, and settings is the key to achieving optimal performance in Bethesda DX11 games.
