In my opinion, SH3 remains fantastic fun especially due to the tireless efforts of our modders, however the advances in reality come at a cost to your PC, and to really enjoy the latest mods, you may need to have uprated your machine to a higher spec.
This done, we have GWX 3.0 OLC Gold to modify it further, and then there is War Ace Campaign, slightly different, but still great fun, with other superb Graphics updates such as GUI omongst others.
Check Venatore's drive through, and the downloads section above to see the vast array of updates.
Good luck
