Possible FXAA issue

No worries, it was a pleasure besides it increases my post count

Just a small update since July UDK is out. I tried it but it sadly didn't fix the problem

Well i guess we can't do anything, does this get reproduced with another Post Process not the hiteffect but another one ? using your settings i had never noticed this issue before because i never used the same settings than you,

Yeah I get the same effect with 3 of my own post process materials, a heat haze effect, a underwater wobble effect and chromatic aberration effect

Alright so it's got to do with the DX9 render thing, i still do not understand why it would work with DX11 but not with DX9, and the weird thing is that you need to set that World setting in DX11, but as you said it does not give the result you want so it doesn't work in both IMO, alright what was causing the issue again, the UberPostProcess or something else ?

DX11 and DX9 don't handle shaders the same way. This could explain the difference.
