I´ve been using P3D with Sweetfx from the start through all versions with great performance, I find it pretty much essential, at least to tone down the saturation and sharpen a little bit.
Now all of a sudden I get a strange behaviour, Sweetfx works after a fresh install, but as soon as I change the display setting in P3d the effect is gone, after that it still works on start of P3D but quits after i click the Menue or go to full screen, no error or whatsoever just no effect.
I´m using the current 344.48 Nvidia driver on a Win7 64bit system, I rolled back the driver to a previous version but that didn´t do the trick either.
The funny thing is it appeared like overnight and is not related with 2.4 as it worked with that version.
Maybe someone has experienced the same.
