I've almost finished this game with one of the most complicated config (Atom D2x00, SGX545) using the T2Fix patch but with the old Directx6 renderer and windowed mode, the only way it can run with Win 8.1 without problems but the frame rate that's slower than the medium-end config of the 2000 (from 10fps to 30fps).
What I think I understood from this experience is that the PowerVr SGX545 gpu would easily run this games MUCH faster with the Directx9 renderer (I ended up testing some times the game with it but the menu is unreadable but once the game start the frame rate seems to be like three times higher but the graphic seems to hang while the games still runs but until that happens the frame rate sure was higher) but probably some drivers/Win GUI incompatibility not being supported officially with this o.s. force to use the old dx6 renderer that itself can't run enough fast too cause probably only working in windowed mode, maybe for how Win 8.1 works (I read on this forum old threads about old games running slow with Win8.1/10 for such possibility) or cause the GPU might runs old games with some compatibility logic mode cause 3DMark2000 get 1300 points.
I attach a photo of the game menu with the directx9 renderer enabled in the cam_ext config file, the menu is running the sound is ok the mouse cursor is not visible but somehow I can get to enter a new game. I tried different wrappers to OpenGL but I don't see any differences. What would you suggest trying?
It seems the gfx errors in the menu (the pixel, the colors..) are variable with the GUI of the o.s. and happens as well as with the game videos running until the game start where for few seconds the rendering seems like perfect.
With the Dx6 rendered windowed both the menu and the games runs as expected but slow.
