<----System and OS Cat 10.5 drivers FPS counter doesn't impact but 1.3 fps, where as the Flash being on imposes a 49.2 fps and 1629.1 MTs single texture / 10559.3 MTs multi texture! Took me quite awhile to track down this strange FPS drop when ATT was loaded :\ I do have a decent amount of items loaded in, since it is Crossfire double all these: GPU t, Core MHz, Mem MHz, GPU Usage%. Tested with 3DM2001 Nature Demo, Fill rate Single Texture and Multi Texture. As I'm sure you're asking "Why?", well because I had it downloaded already, I'm on a poor connection (long story) and capped monthly bandwidth. Plus I wanted something consistent AND what would provide an easy task for my system so I could gauge exactly how much of a performance hit is imposed by the registry changes I make... Now the data, if you want it: Tests ran w/ 16xAA Wide-tent (32x samples), ASTT, ASBT, EATM, AA Mode set to Adaptive MSAA (not that it does anything compared to normal MSAA mode), 16x HQ-AF and a few other less important things also turned on. 3DM01 settings: 1680x1050, Triple Buffering, DXT1, OSD OFF Nature 151.2 fps Single 12794.5 MTs Multi 35294.5 MTs OSD ON Nature 111.4 fps Single 11165.4 MTs Multi 24735.5 MTs I think that should cover it. Onto the question: Nature of the beast, or should ATT's FlashOSD not be impacting performance that badly?
