i'm having a hard time unwrapping a model on my laptop. i dont have access to my pc. when i try to make a uv selection in the uv editor in XSI 7, it takes like 10-20 seconds to even make the selection. vertex selection in the main viewport also runs slowly. poly and edge selection are better but still a bit crap. My laptop…
Same as JMYoung here, I don't use xsi, but I know Silo throws a selection tantrum when anti-aliasing is turned on with some graphics cards. Try forcing it off and see if that helps.
