GWX 2.0 without the graphical changes?

Hi
Is there any way to install GWX without the graphical changes? Just use the gameplay adjustments? If i install the full thing, going to sea takes 6 min to load! With vanilla sh3 it takes around 40sec which is much more barable.

It must be some new graphic i recon that my comp cannot handle... Also, is it possible to not add the large overlay picture around my uboat in mapview? I liked it better with just seing my uboat as a "ship-body".

Thanks a lot
Erik
