Before this patch I had no such issues with full screen mode. I may not have gotten the best fps comparing with similar sorts of games, but it was stable and never had a single crash.
Admittedly, I had stopped playing it due to the low fps which I mentioned numerous times, one of those here:

and
http://www.train-fever.com/forums/topic/are-we-likely-to-see-any-additional-performance-improvements/
But since the recent patch full screen is impossible.
Navigating the menu takes 20 seconds just to get to an option, then sudden crash with the TDR error.
Alt Enter to switch to window mode does allow it to recover though and does make it playable, but the performance isn’t much better than before, it’s still poor considering and comparing to other games as mentioned above, CIM2 and C:Skylines.
Anyway, I just don’t feel like playing and building up to a point where the fps hits 20 any more.
So as above, don’t worry about it… I have had issues with it since release and yeah things have improved here and there but clearly it’s never going to meet my expectations, which are not very high.. of being able to play with at least a minimum of 30fps lol.
Anyway, the dev’s or at least Basil said that 20-25fps was as expected at the time I was emailing them and advised me to play like this, lol… “Until then we can just suggest to not have multiple PIP windows open and to play small or medium maps if you are very “fps-sensitive”.
So, I now finally give up 😉
