yes thats basicly the problem. sorry i wasnt informative enough
i have new models en masse (i dint use any stock model) so trees, playermodels, weapons and all that stuff. its more detailled then the stock models but the computers of today are betrer then the old ones

for a model with 4k triangles it tooks 30 minutes. is there a way to "manually" munge the models? (so calling pc_modelmunge myself) ? i'll have a look in the munge.bat. (if i can do it manually i can munge more then one model at one time)
the model i am munging is only those 4k triangles theres already a lowrez included (but no collision mesh, maybe it takes so long because it has to generate a collision mesh)
anyway thanks for support guys
