Tough but yea one game probably ain't worth a system that can't run it if all else is working well. Also sometimes it's better to leave old GPU drivers alone and only update if the patch notes makes sense towards an application you need updated; otherwise new drivers can sometimes cause more issues than older ones.Thanks for your concern. Honestly it is not a big deal, ofcourse I would've preferred the game to perform better than this but at this point I am not going to do anything more than changing a few settings from nvidia control panel because I'd hate to accidentally break my perfectly working system just because a porn game refuses to work properly.
Speaking of control panel, I just toggled a few settings on and off(vsync, gsync, framerate limit etc) but they still didn't make any difference in the game.
My graphics card driver is at worst probably only a few versions behind current latest version, last time I updated it was when that robocop game was released.
DirectX updates are downloaded by automatic windows updates as far as I know.
Perhaps another important thing to note is that I am having this problem only with this game. No other game does this. Seems to be an optimization thing. Fortunately it is just a porn game so I can roll with it, if this was some action oriented game it would be a game breaker.
EDIT: I've tried deleting mods to see if they are causing this problem. It isn't a mod issue. I've also deleted bepinex itself. Still not good.
Cheers
