ATI: Auto 2D/3D overdrive problem

Anachronous · 03-22-07, 05:45 AM

As you may or not know. Modern ATI cards only run at full speed (core/memory/voltage) when running fullscreen 3D, compared to 2D desktop mode or windowed games where they underclock to stay cooler/quieter. This isnt usually an issue, unless you play lots of games in windowed mode (like i used to with my old Nvidia card). In my case 2D = 508/600 where 3D = 655/1008.

I noticed today on my x1950XTX, that on rare occasions while starting and playing SH4 the speed was still at its default 2D setting and hadnt bumped up the speed to fullscreen settings.

Im using ATI Tray tools OSD to monitor speed and temp. I thought i'd check because as you can imagine, this has quite a noticable effect on performance.

Im wondering if anyone else has noticed this? Cats 7.2 btw. With version 1.0 and 1.1 of SH4.

PS.. I reallllllly need some FSAA :P
