full screen flickering in ppsspp?

[unvaluablespace]

hey guys, I am really confused by this. Ive never had any issues before, but now suddenly when I go fullscreen in games, I get flicker, and even notice slowdown. im posting this here because I only started having the issue shortly after using ppsspp, although I am in no way pointing the blame at ppsspp, I am merely asking for help.

whenever I attempt to go fullscreen, I get flicker issues. i bought and installed crysis 1 on steam, around the same time as ppsspp, and after finding that it doesn't do 1080p in 60hz (without some sort of weird workarounds) i started getting weird full screen flickering issues in ppsspp and other games\programs. but heres where it gets weird: its not on many games at all. only a few. I have NVidia and 3dvision, whats weird is when i enable stereoscopic 3d support, i get no flicker issues in ppsspp and other programs. once disabled though, that's when the flickering occurs. turning down the hz (59hz instead of 60hz) does nothing. i still get flickering.

I recently bought an SSD drive for my system, and did a clean install, everything reformatted, windows reinstalled, etc. but the issue is still there. I am using the latest NVidia drivers, and updated to windows 8.1. the thing is though, I was using these versions even before the issue started, and a clean install did nothing to fix it.... :-\ i am at a loss. I run my HTPC setup on my tv, so it only goes up to 60hz. again, this was never a problem before, so what could be the cause now? :-\
