XP corrupted over time so a fresh operation system install usually did wonders.
I don’t know how many times I’ve reinstalled XP and win98 was even worse haha.
But for a while after that they usually run kinda smooth.
Win7 is MUCH better and my DAW boot with only audio stuff is a little snappier than my other boot labeled LAB is maybe kinda bogged down by all sorts of crap haha
Hard to tell though, it could be imaginary, and I’m not using the same programs on both so …
A fresh OS is a good tip, me thinks, if you haven’t already tried that?
