zenox98 Much thanks for test and for the screenshot.
I see, then, one of the problems was the OffsetX, in my case works correct with 0.0 or 0.5 but for other people not, have to be 0.0 like you and i guess for the other guy :S . Why the hell are not all the shaders compatible with all the cards, even with the same developer, i also have NVIDIA. i hate this incompatibilities things
I guess other of the errors can be the OffsetY that will explain we some shaders not appears, because they are in a -0 on Y coordinate instead move the shader in negative numbers.
Also there is some shaders that works but not correct, i guess because the change of the OffsetX and other things.
I don't know how to fix that to be compatible with all the cards sorry, hope Gigatron finds a way.
