I'm at work right now so I'm not able to try some of those suggestions just yet, but when CM was working "right" a month ago, It was under software mode, ugly smoke, no transparencies, etc.
The problem I'm having now (other than the mouse not working on the screen edges) is that some most of the tracer fire is not visible, and some of the polygons of the units and buildings are not showing up. So it's not really a transparency problem, but parts of the units aren’t rendering.
...How can I force the game to run in software mode? (Beside take out my 3Dfx card on run my old ATI 2 meg POS.
...Is there any way to set the resolution, color depth, etc like every other 3d game?
I’ve can't remember all the things that I've installed, mostly a lot of demos (Tony Hawk 2, Dues Ex to name a few.) but those games run fine (great really for a 5 year old computer) I'm having this same problem in OS8.6 or 9.1 depending on which drive I boot from.
Thanks for all the suggestions, I'll try all the suggestions listed above, and see if I can flash the VooDoo ROM back to an older version too.
