that's why banging on larian for the optimization will be a fool's hope. usually.
Optimisation is one of the last things done for the game before it is release, so it reasonable to expect that the game will run better but to what extend I don't know. I do say, that on my old laptop there was a world of different between D:OS2 1.0 and D:OS2 enhanced edition, or whatever it was called. Fortunately for me, I can run BG3 just fine as it is.
