Theoretically this should be fixed. If someone still got this, then please post your bug on the forum.

Michal, I am experiencing a strange FPS problem. I see other people having soft fluid movements and mine are extremely choppy. It is walking, the mouse is delayed and choppy where ever I am in this game.So it is very hard to play this game. I have not read any other reviews reporting this problem so I am directing this to you. Please make a change for players that truely love these games but have problems.-Darkside_317

I get FPS problems after playing a while, and when exiting it's downright choppy or even hangs up, having to use the Reset button on my PC. I'm thinking it's not so much our PC's, but a memory leak somewhere. Have not managed yet to narrow down to what causes it, but it seems to become progressively worse when changing screens, like when mounting/demounting turrets/engines, and moving from workshop to museum or yard. This changing screens also occasionally results in not being able to use the pneumatic ratchet anymore (bolts no longer appearing), and not being able to use the crafting table or to open the door to the paint booth.
