I am useing "Flight simulator X" steam edition. And i am useing DirectX 10 mode with(SteveFX DX10 Scenery Fixer V2.3), but every time i use "SweetFX" the game crashes after 2-3 minutes with whatever settings or presets i activate. Please help us out here! By the way, i use sweetfx in euro truck sim, but it works perfect.

HEy guyz !!!.. i'm back... and i found the solution to this!!! If anyone of you has this problem, the solution is simple....just uninstall "KB2670838" from windows updates.... That is all you need to do ;) ..... and now i'm in love again !!

Glad all is well folks :D
