PPSSPP slowed down all of sudden

[FediOK]

Hi guys, the emulator was so awesome for me, i played my games on a very decent pc, all of them on cool settings and such. They used to run smooth and chic, but today the emulator is working absolutely SLOW. I've tried rebooting, changing every possible graphic setting on the emu (but it was not needed a week(!) ago) updating my video drivers and reinstalling the emulator itself. Nothing worked for me.
Please someone help me, I am desperate. I am pretty sure the PC hardware works just fine, so i will try and reinstall Windows as a last resort.
Any help will be apreciated
