I'm trying to get SH3 with GWX 2.1 + OLC2 the environment pack (not the GUI) and some mods to work on my laptop but it seems the framerate is just terrible and the game unplayable.
The game works nice on my table-PC but would be nice to get it to work on the laptop as well. I guess that's impossible. I've tried vanilla SH3 and without OLC2, it's a little better but still not very good. Bit odd cause I can get many other grafix - heavy games to work somewhat ok but with SH3 it's a no-no. I'm running a Vista machine with enough RAM but the grafix card is probably the hangup.
edit. Actually got the game running at least ok by fiddling with the particle density.
