Hello, yup I'm getting rainbow outlines occasionally, generally wood paneling, back ground objects. It will also throw evenly spaces colored squares at start up sometimes, then crash, like a jet with no wings. Running liquid gtx470 and have it ovrclkd dont know if its causing compatibility issues. Ran Kombuster throughly and then nudged it down a little. All's Well there. Just don't know if it will conflict with the game. Have it on ultra high settings.
