I experience the same bug. This happens after a few minutes of playing Train Fever, in different situations, so I do not have a clear reproduction instruction. Unfortunately the game can not be played like this.
Switching TDR off (TdrLevel=0) leads to a full computer hang instead of a TrainFever crash. Is there a way I can provide you with more debug information, or some some low-level gl settings I can try?
System:
- lowest Graphics settings
- TrainFever build 4831
- Nvidia GT240, driver 340.52
- Windows7 64bit
- Quad-Core Core2Duo Q8400@2.66 Ghz
- 4GB Ram
cheers
