Hmmm...ok now i'm a little peeved.
I'm now playing through Splinter Cell - Chaos Theory, up to the Hokkaido level, a few rooms before I reach Neddich. I've been playing the entire thing right through to this point on the Catalyst 7.3's with HDR+Tonemapping enabled and 2xAA (and it was definitely working...AA was applied for sure, i'd be a retard not to see, and HDR/Tonemapping was
definitely also on, I tried switching them off/on at one stage to see the difference for curiosity's sake and I definitely had it on). At one stage, it was dinner time so I did a quicksave and quit the game... a few hours later I came back, logged in, fired it up and loaded my save only to find that AA had been completely disabled!
'Wierd' I thought, so I quit the game and relaunched it to see if ATT skipped a beat or something, but no joy. Long story short, i've tried reinstalling my videodrivers (drivercleaned each time), i've tried an older version of ATT (and a newer beta) but no matter what I do, AA just wont apply any more. I disabled HDR/Tonemapping in the advanced shader options ingame just to be sure, and sure enough AA was then enabled just fine even with the ingame option set to disabled (forced via ATT). But no matter what, it just no longer refuses to work with HDR/AA. I've played this far through with it just fine and i'm not playing another minute until it starts working again, this is just pissing me off.
Anyone have any ideas, or encountered this when you played it? I want HDR for sure, but I also can't live without AA, so it's a catch-22.
