Subject: Re: Signed GPLPV drivers available for download

i have very strange effects as soon as i install the GPLPV drivers under 
windows7 (64bit):

- no network connection as soon as anything which accesses the graphiccard in 
3d mode is started; thats what buffles me most... i can't really tell you more 
than that, its really that strange (first i thought of a virus or something 
like that, but i was able to circle it down to the gplpv drivers,..)
this also happens with non-signed gplpv drivers, and also with a version prior 
to 308 (was it 238?)

- really better read-performance WITH gplpv, but much worse write-performance:
here is the performance without gplpv:

here WITH gplpv:
