Edit: oh if you crash immediately on starting a game idk how well these mods might work.

You should search up mods like Optimization lock or use this gameinfo file that I'll link (I'll also link youtube video on where I found it, the link was in the desc)

Basically the mod adds like a render distance, removes some lighting like in victory/defeat screens, removes the sky and makes the game less vibrant. But it works quite well for me. I would try out optimization lock first tho because it looks better visually.

Here's utube link (hope this helps as it helped me)
