well i just played some ut3...it's not nearly as good as i thought it'd be but it's at least somewhat playable...

There are many question that need to be answered before anyone can help you decide on what to dump money into. That error message is only your monitor telling you it can't handle either the resolution or the refresh rate. Start with your monitors max resolution if it's a CRT or the native resolution if it is an LCD. Do not excede this setting in the resolution. I don't remember the other settings for video in UT3 but the resolution is important to your monitor. It is possible to damage a CRT by settings it to something it can't handle. The rest of your machine is important to this game as well so you might want to post your system specs. If you don't know the specs, find out what they are from your manual or the website.so...what the heck else would i need to make it look better? i'm kinda disapointed with how it looks now, and when i try to turn the settings up, i think the monitor can't handle it. it says out of range 33.6kHZ/60Hz. does that mean i need a better monitor?
do i need more RAM, or would that make a difference in the way it looks?...or a new motherboard and cpu!? noooo!!! well i've already bought the graphics card i guess i might as well make it work right.
or is there something else i have to change on the settings that would make it look clearer. hopefully this doesn't start to get too expensive. i have a paycheck that i'm willing to spend on the computer...
