If you have an NVIDIA card, bump up the Digital Vibrance. It's in different places depending on the driver version, but it's there. Rightclick a blank spot on your desktop > Properties > Settings > Advanced > Then the tab for your Video Card. Look for Device Settings > Color Correction. Mine is in the NView Display Mode section. It used to be somewhere else in older drivers.
Anyway, you bump that up a bit and then you can leave the gamma setting in Glidos a bit lower. You get a more saturated, high contrast look in the game without the cloudy washed out look of raising the gamma too high to counter it being too dark.
It looks excellent.
I'm sure ATI has something similar.
Read very fast and quietly: results may vary, use only as directed, may not be appropriate for children under 12, images photshopped because the darn things looked the same and wouldn't show the effect, do not use with alcohol, video card sold sepperately.
