It has arrived and runs great on my P4-2.4 and Parhelia. I was concerned it wouldn't be a DX8.1 game but the demo said otherwise. It runs @10x7 with low to mid level detail settings just fine.

It only supports the Parhelia in the Matrox line according to the box and insert, but the printing may have taken place before the P650/750 were available.

Only disadvantage I can see with this installment is that it has less detail adjustability so it may be hard to make run on slower systems.
