I had Tera and Sweetfx working flawlessly, had being the keyword. I reformatted yesterday. Now everytime I have Sweetfx "installed", Tera crashes on boot. Does Sweetfx have any prerequisites to working properly? Windows 7 Ult.64 i5-3570K AMD 280X Game running from steam, same as pre-reformat. Tera and all other games work w/o sweetfx. -installed DirectX End User Runtime --no fix

Maybe try using the x64 sweetfx files? That usually works for me.
