Hi TC,
Panzer Commander certainly has some problems with XP and modern video hardware.
You might try switching, is it real world physics? off, as it usually crashes the game within a short time. For me game plays OK if I do that.
Also models tend to be slightly see through as I assume modern video drivers don't support the old way of doing rendering sequences.
See if any of that helps anyway
Pity 1.4 wasn't finished.
Still a fun game and the campaigns are great.
Cheers
