Valcor Posted March 6, 2010 Share Posted March 6, 2010 Hey, I'm stumped by this one. For some reason, my GTX 285 keeps reverting from 3D performance clock speeds to 2D performance level clock speeds. It happens both in FSX and tested it in DCS Black Shark as well. Needless to say, it cuts performance in half. Temps are well below normal operating range. It typically happens 1-2 minutes into a new flight and a brief pause will occur in game, followed by the clock speeds drop. I've tried 2 different drivers and double checked Win 7's power saving mode. I'm using RivaTuner which should keep 3D clock speeds locked but it's not. I also tried EVGA's Precision with the same results. Any idea on what I could be missing? Link to comment Share on other sites More sharing options...
Wolter van der Spoel Posted March 6, 2010 Share Posted March 6, 2010 something is wrong then, un-install all nVidia related stuff ( drivers ) delete hardware in hardware controlpanel ( your vidcard ) reboot when it tells you it wants to install drivers for the new found hardware say not and install the latest drivers Link to comment Share on other sites More sharing options...
Valcor Posted March 7, 2010 Author Share Posted March 7, 2010 As it turns out, Bufferpools=0 was causing my card to freak out and reset my Vid drivers to 2D clock speed settings. I don't recall this happening with some other drivers so I'll have to find the right ones. Hopefully the re-worked WHQL's get re-released soon.
