Problems with AA
 

I've been trying to fix up the Anti-aliasing in this game, which I can get to work great in SH3
but this game doesnt have a profile setting for Nvidia profile inspector
And the regular control panel doesnt seem to change anything in game

SH4 would use the same settings as SH3, and does not go very high at all... maybe a 4x?? I cannot remember. Fifi has a posting, as well as others, as to the Profile set-up.

I struggled/struggle to keep this game looking good, and the best thing I've found is using reshade—specifically, GaussianBlur and FXAA. For whatever reason that, keeping anti-aliasing down, and using graphics mods works for me. Of course, then comes increasing time compression and it all suddenly vanishes, so you're forced to slog around the pacific at 256 speed hoping the weather doesn't disappear, but when it works, and as you can see it's a struggle, nothing comes closer to Silent Victory.
