Hello, from my knowledge the graphics in the UE5 version of the game depend on these things.
(correct me if I am wrong)
1) OS and driver compatibility - newest, up to date Windows and GPU drivers will work better with UE5
2) VRAM of your GPU - minimum recommended is 8GB of VRAM
3) horse power of your CPU - powerful single threaded processor
4) horse power of your GPU - yes, it's actually the least relevant
The older UE4 version of the game is a better choice for anyone struggling with UE5.
I think it still holds up very well.
Some recommendations for people trying to increase performance in UE5 version
- lower Shawod Quality and Texture Quality settings
- disable Virtual Shadow Maps, Lumen and Fur
- for Nvidia GPUs - enable image scaling in GeForce Experience
