So, I had Diablo II and LOD installed, and compatibility settings set for XP SP2, and it ran PERFECTLY, no lag even with the 1.14b patch installed. Then, all of the sudden it just started lagging whenever I moved my mouse, for no reason I could find. Nothing running in the background, no spyware or viruses, NOTHING. Tried installing the Glide Wrapper, that didn't work, no combination of compatibility settings works. The ONLY thing that gets rid of the mouse lag is adding -w -nofixaspect to the Target line in properties. And its SO TINY in windowed mode!!! What do!? How fix!?
