I have win xp pro 2600 and im sure u guys know that by defult on my geforce gts32mb card after it installs once booted to desktop it has the resolution at 800x600 32bit high mode and the background is that i think mountain lokking thing something like that i forgot cause i reinstalled 2000 here, but anyways ohh the grass scenery, ok i installed quake3 demo just to see how quake3 plays it played well very well but my issue is when i put my desktop to 16 bit like i always had on other windows versions, and then loading up quake3 then once at the main menu of quake3 i exit so i can go back to desktop but what happens is once the exit screen goes away on quake3 it freezes right at the desktop u could see some of the icons coming up but the rest of the screen is black and i have to manually resart the pc, but if i put it back to 32bit mode in windows desktop settings the issue does not happen, so i want to know what u guys think it is is it a demo quake3 issue? ohh yeah if i put the background the "none just like in win 2000 pro just a plain jane blank background no pretty background image the freezing issue does not happen when its at 16bit mode. i even istalled 2 different new xp drivers and uninstalled and reinsalled also. could it be that the default grass scenery background is so colorful that by putting it atr 16 bit and when opening up a opengl game it cause a glitch or something? give me some opions guys.
