aleader Posted October 7, 2002 Share Posted October 7, 2002 I recently replaced my GeForce 2 MX with a new ATI Radeon 9000Pro card. I installed the latest drivers from ATI for it. Card is a huge improvment in speed and visual quality in everything, but now Fog doesn't work in CM or CMBB . What's the problem? I'm running XP Pro. 0 Quote Link to comment Share on other sites More sharing options...
L.Tankersley Posted October 7, 2002 Share Posted October 7, 2002 ATI cards on the PC side don't support fog in CM. On the mac side they do, but there are ... other issues. 0 Quote Link to comment Share on other sites More sharing options...
aleader Posted October 7, 2002 Author Share Posted October 7, 2002 Please explain... Does this mean the ATI drivers don't support them, or that CM isn't written to support ATI cards (unbelievable :confused: )? 0 Quote Link to comment Share on other sites More sharing options...
Cull Posted October 7, 2002 Share Posted October 7, 2002 aleader: I just put together a new system and bought my graphics card based on this very issue. I really wanted the new ATI card, but couldn't live without fog in CM! I'm not positive, but I believe the problem is ATI. I have seen other references to the "no fog" thing with their cards in other games, which really is unbelievable. Especially with their brand new cards---no fog?! Anyway, I ended up going with a g4 Ti4400 card just because of it. I couldn't really get a definite answer, and didn't want to gamble. 0 Quote Link to comment Share on other sites More sharing options...
Schrullenhaft Posted October 7, 2002 Share Posted October 7, 2002 ATI video cards don't support fog-tables (also called Pixel/Particle Fog) under DirectX (they do under RAVE on the Mac). Instead ATI supports Vertex Fog, which isn't what CM uses. There are a number of other games that have this problem with fog effects and ATI cards. I have no idea if this is true under OpenGL or not. So to summarize, it's a problem with the ATI drivers and they haven't changed their support for fog-tables in years. I don't suspect that they'll change it for the latest Radeons either. 0 Quote Link to comment Share on other sites More sharing options...

aleader Posted October 8, 2002 Author Share Posted October 8, 2002 Damn, that's a shame because the card is so good otherwise (Madden looks and plays fantastic :eek: ). I got it 'cause I have a wife who doesn't believe buying computer stuff is a 'worthwhile expense' , and it was quite a bit cheaper (only $83 US) than a GF Ti card. Really, I rarely play games in CM with fog, but it's a kicker nonetheless. What are some other games that are affected by this stupidity? 0 Quote Link to comment Share on other sites More sharing options...
