Hi Community

Simply put with TXAA enabled the game looks beautiful and smooth an all but when I turn my camera some times the foliage and scenery flicker, it does not do this if I switch to the FXAA low setting (I wish they have a FXAA high setting), its big major flickering but it looks like a mini flash grenade going off in the distance for a split second.

Does anyone know a fix for this flickering or is it just the downside to using TXAA.

Regards
