Greetings. I am now using ATI Radeon 9550 (Original Version, with ATI Offical Driver 4.9) These days I am playing the BioWARE's D&D game - Neverwinter Nights. Since the requirement of this game is quite high, and I need to overclocking my display card in order to have a higher frame-rate But when I turn on the ATITool, and then start the game... the most strange thing happens.. The game just HANG imediately before the Game Menu showing up! I have tried to change the driver with a newer version (but it becomes worser... but just ignore it) Later I find to close all currently running applications before enter the game, my GOD! Everything goes OK!!! So I tested for all apllications (just closing and switching on them... repeatly) and enteing the game. Finally, the problem is due to ATITool.... I also tested just left ATITool running without any overclocking. but I still cannot enter the game. Since this game is a very good game, and I really want a higher performance during playing this game... Can anyone help me?
