I have my Visiontek Ti4400 o/c to 300/600 (default is 275/550). If I push it to 305/610, I get some small flashing rectangles and larger flashing triangles in some games (mostly in NFS-HP2). Is this what is referred to as "video tearing"? I have installed a copper GPU HS as well as some decent RAM sinks, and the heatsinks are warm but not hot at all after playing a game (not much heat difference between default frequencies and the O/C ones), so cooling is not an issue. So, naturally, i want to go further I have the option in BIOS to increase the AGP voltage from 1.5 to 1.6, 1.7, and 1.8v. Would increasing the AGP bus voltage help the tearing problem (if that is in fact what the issue is)? I understand it will heat up the components a bit more. Really, the only reason I want to do this is for NFS-HP2. I find if I use the behind-the-car view, I get pretty crappy FPS (around 30-35 at a guess). So, I have been using the front bumper cam which seems to help a lot, but I don't like as much (can't see how close those #$@! cops are). I have in-game settings at 1024x768 @16bit color. I do want high car and world detail. I think my hardware should be able to do this reasonably well. I get about 10,800 in 3dMark (I know that doesn't really mean much, but it gives you people some idea where I am). BTW: I'm using 40.72 drivers, vsync is turned off, FSAA is at 2x, texture sharpening off, and Anistropic is off. The rest of my H/W is in my sig. If anyone has any other ideas how to help preformance (aside from reducing settings), please share the knowledge!
