Thread closed because you continued to discuss a problem/bug you experienced there. The D2X-XL bug and support request trackers on SF.net are the right places for this though.
I found why. High quality makes Pyro-GX turning slowest, low quality makes fastest as normal. But textures are ugly like old DI and DII. It's not fair.
But I have COD, BIA Road to Hill 30 / Earned in Blood, MOH: Allied Assault War Chest, BF 1942, and RtCW the platinum Edition. They are fine, fastest, high quality, and all high.
D2X-XL has between low and medium 3D model. It is not be!!
