I can confirm this. Running TTDX under windows eats about 25% of my CPU 
time (according to the task manager), no matter what is displayed or how 
many vehicles are moving around in the windows. Opening train windows of 
passenger trains do not affect this, no matter how many of them are 
opened. Opening one(!) window of a freight train (DBsetXL BR194 + 
Refrigerator wagons) makes TTDX need 100% CPU time, resulting in choppy 
display. For other freight trains, the problem is similar, but not that 
drastic. There is clearly something wrong there, I doubt a P4 with more 
than 2GHz is too slow for this game ;-)

Now could somebody please explain to me why this happens? It somewhat 
spoils my gameplay if I cannot open train windows to my liking without 
experiencing such display problems.

I tested this with several alpha versions and 2.5 beta 1 (all windows 
version), they all showed the same behaviour. Could this be in any way 
related to DBSetXL, certain Patch features it uses or something along 
these lines? I simply cannot believe that the type of wagon of a train 
matters so much... Complete config and example savegame can be provided.

Greets,
Uwe
