Sufyan: I need to lock my GPU at 30-35 FPS to fix all those severe gameplay problems you have surely heard of. It is very easily done on nvidia cards using a free third party program called "nvidia inspector".
traingineer: So if I lock the fps at around 30, the game will be fine? No severe bugs or problems?
It will not perfectly replicate the experience of playing it on a time period appropriate computer, there are still some potential physics based problems most noticable in some of the jumps you have to do in the story. Also, I'm quite sure the clouds are moving too fast.
I have not finished the game this way, but I think it is very playable. I guess that if there is some truly game breaking physics bug later in the game it is probably possible to get past it by lowering the frame rate even further temporarily.
Pseudoman: I have had a similar experience with the game.
Using the stock Nvidia drivers, I use "adaptive v-sync" that locks to half of my monitor's refresh rate (~60hz / 2 = about 30 fps). This solves most, if not all, issues for me.
Brilliant! I did not know this option existed in the nvidia control panel. Upvoted.
