as you can read on the efxMod Homepage the efxMod Shadersystem is detachable AND it is Multi-Language.
Can you try to read the homepage, the next time?

Choose the Standard Stable Build, if you're not a nVidia Graphic Card User and if you want a smaller EXE.
Choose the Alternative Stable Build, if you're having problems/bugs with the first one or if you use an nVidia graphics card.
Motion Blur has been disabled/removed in this release, because this is just a small ESU (Engine Stability Update).
