Hi all
it is no server problem it seems its the grafic card or driver
i use an gforce 6800gt
with an gforce 5700xt there is no problem at all
i tried to use the same driver version like the other pc with older card no success also i did try some newer and older
if someone also has a gforce 6800 gt and does not have the problem it would be nice if he could tell me wich driver version he uses
it seems to be a problem with new shader 2 and / or 3 (of grafic card )
i think this post is now in the wrong forum or wrong place in forum
thanks for all your help
