Hey! had been really annoyed at this bug, so I checked out the tool! nicely done!
some notes from my experience / suggestion
I also downloaded the source, since the compiled version would not work..
1: I have 3 HDD's with steam games, this will bork things (dirty workaround is dirty... folder lookup breaks)
2: I removed the required admin rights, everything seems to continue working
3: would be interesting to try and have a hotkey that just toggles the rays off and on, then just hit it when lag starts
4: compiling the code in debug seems to have created some local VS sandbox mode that my pc was unhappy about, a release compile may fix this if other users face it
I will try and find free time to look at fixing these, ping me if you want some help
