I have got SH3 commander and GWX and it runs fine (20-30 fps in harbor and with LOTs of activity around and 60 out by myself) i just wish my graphics card was alot better so I could have better looking water (My water all looks opaque and ugly at the moment, no reflections) but I think ill be getting one soon
and if I get a better CPU all together.
Say hello to SH5 and IRAI to me as well
cant wait to see the new damage in GWX!
