D9200 and PC games -- Quake III-- HELP

[woodworker]

I have a D9200 with the ArcadeVGA video card and XP OS-- the setup works incredible for MAME apps. However when I try to run PC games such as Quake III the screen brightness is so dark the game is unplayable. I can up the brightness controls to barely make the game playable but at the cost of washing out all the colors. Anyone else having this problem or any suggestions?
