Just advice if you want to navigate more easily in windows folders use Total Commander or something with hidden system files enabled(even unregistered version works fine)
1 First backup your own save files (copy them somewhere and delete),
2 copy saves from the archive which you want.
3 launch game and try to load.
saves 1-54 is manual saves, others are auto saves, and don't touch other files there are settings file, etc.
mine save 54 which is not in archive is last of this version lack only few scenes.
in archive you can find 2 folders 1 one is up to 200 or 299 seeder.
and second one is last saves up to 599 .
on save file see which day it is to more easy to find what you need.
Buddy first thing do you have integrated video on your CPU?, if yes turn it off in BIOS (Let this shit RIP there forever)
If you are playing on integrated video chip...
if you don't have integrated, you have left with 2 options hardware and software(OS included)
If you have any other video card try it.
Also any boost and settings in OS try to select to normal, no CPU and GPU overclocking and RAM in Bios and OS.
It's not the place to talk about it, you can find guides, google it. If you have this problem it must be not only in this game.
