Missing effects and animations

hi, i'm having a visual problem were the effects just randomly disappear. this only happens on the FAF client and not through Steam. i've tested changing the gfx settings and reinstalling FAF and supcom, but nothing seems to work. does anyone know what this is, or how to fix it?
