Runs nicely.. though, needs more user end intelligence than nvidia products if wants to get all potential out (hmm, another good reason to call them nvidiots, they dont need to be intelligent with the card)
In AH, smoke is no more issue as it was with TNT2.
TNT2 = 5 fps in smoke
Radeon plus whole field smoked up = hardly goes below 20 FPS, most Ive seen was less than split second 14 FPS.
one smoke goes +40 FPS. (most FPS goes for buildings

)
In tower 75 FPS and in flight somewhere 55 - 65 FPS.
oh, thats with Cel 566@850 and 256mb ram.
Though, Radeon is not Rogue Spear friendly for example.
Sometimes I've seen missing faces (triangle holes) in the enviroment and when I moved all the textures of one map to backup directory to make up a screenshot of operative, it didnt work like it used to with TNT2 - operatives were having some missing faces.
Fog is also missing in this game.
With TNT2 fog was gone by turning off table fog, but with Radeon its same is it on or off, no fog.
but RS gets somewhat more alive when toggles on GameGamma feature or so (actually its on by default), since it increases saturation, but its not good at all if surrounding is mostly white.
but thats easily disabled.
However, Aces High works nice. (but still clouds do kill some FPS)
At least desktop looks bit cleaner with fonts and stuff than used to with TNT2.. hardly noticeably though, but some small fonts can be seen better.
Operation Flashpoint demo has some graphics mess up issues in the forrest and missing tank cockpit graphics.. though, im not sure whether that is Radeon or game issue.. probably game issue mostly.
but its cheaper than Nvidias and offers about same (if not better) performance at 32-bit color depth.
