Strange problem with Korsun '44

[Panzer VI]

Having this issue with Bulge and Campaign Leipzig.

I would have thought John Tiller would have had this fixed before he would start putting them in his games. Bulge is unplayable slow now. In Leipzig it starts off reasonable then gradually goes slow.

Disabling some of the Hardware acceleration works and the game works fantastic, but then my start menu starts acting weird.

Shame that a computer that can play all the latest games with fancy graphics is having trouble over such a graphically simple game.
