This is confusing the hell out of me. The above mentioned "Mark C" fix seems to be the best. I downloaded it from
here, and it made the custom reg file for my machine. But in the readme it states:
Does that mean the windows 'Enhance pointer precision' option should be left on, off, or doesn'take any difference?
Also, it didn't mention refresh rate at any stage during the generation of the reg file? Will it compensate for 85Hz correctly?
