Look down to see what I'm talking about...

Pay attention to the top-right street light that lights up the concrete. Notice the concrete lighting has a rainbow. Also notice the shitty color transition on the front of my awesome comet (the car, for you non-GTASA players). The slight shadow the car is making has a rainbowish hue as well.

Things I've tried and failed (means, don't bother suggesting them)
-Reinstalled drivers
-Fucked with the monitor/in-OS colors - this started the problem to begin with
-Reset color settings to default
-Fucked with in-game settings
