So I installed Windows 7 over the weekend, along with a new quad core processor, new motherboard and 4GB of RAM. Everything else I've tested seems to run the same as before (under Windows XP) or better, though my testing has been limited by a poor quality stock cooler. UO however seems to be running much worse, with jagged lines appearing as I run, occasional slowdowns when running (could be my poor connection), and very laggy mouse movement. I'm happy to run the mouse in a seperate thread, but the jagged horizontal lines are very distracting. Could this be the end of the Classic Client for me?
