Question Extremely weird issue with games installed on Program Files and AppData

[Mercron]

So, long story short, I had been dealing with input lag and a really weird mouse(and drawing tablet) acceleration when playing games fullscreen, and really big loading times, even though I have a relatively new SSD. So yesterday, after months of fruitless troubleshooting, I decided to move those games from Program Files and AppData to... a desktop folder. And lo and behold, everything just works now, 0 input lag, no acceleration and the loading times are almost instant. And this isnt placebo, I timed the loading times from the same game (classic WoW) on both program files and desktop folder. I tried googling but didnt find anything. My question here is, what could be happening that makes my games lag soo much when they are installed on Program Files? Is there any box that I checked that is messing with that?

How did you 'move' this?
Details, please.

I installed a game called osu. It doesnt let you choose an installation path, it install automatically on AppData/local. So I just moved the folder from appdata to the desktop. For other games, I unistalled them and reinstalled on a desktop folder as you would normally.

AppData, Program Files, and the Desktop are literally on the same physical storage device.

I know, thats what makes this thing so weird to me. I can promise you that all the lag and long load times are gone when I put the games on my desktop. I have no clue.
