Same here, MSAA though CCC is checked for application controlled.
Gone for yet another fresh install and left the updater to do it's thing for 15 minutes, seems to have made a difference (no 'aborting'.. message this time). Shadows to medium, particles to lowest setting and I've lost most of the stutter (along with the nice fog effects, which is a disappointment, but oh well) and kept my 50-60 fps. Antilag at limit 60, render ahead 2 has smoothed it right out once more.
Reinstalled OM up to patch 2 again, tested, worked fine with no fps hit at all, even with the improved shadows which I had to remove before. Sunk a ship with no CTD. Put my minor addins like Torp Criticals and seems fine too.
Getting a good, smooth 50-60 in all environments so far, looks like this may have fixed it.
Did go back after all this and tried OHII again... it works ok, but the framerate drop is way too high even with 50% port ships & 20% mines - goes from aforementioned 50-60 right to down to mid 20's with OHII full! Smoother than before but the pc just can't hack the extra traffic, you can see the drop when using time compression, even in empty ocean.
Dropped that and tried OHII light - straight back up to 50+ fps again, so sticking with that for now barring no obvious difficulties. Think something must have gone wrong with the install or the modding process.
Thanks for all your help chaps!
