New comer here!Is SH5 still bugy now?

[lanziqi]

I installed SH5 several months ago and played for a while(haven't known about subsim then so no mod was installed).All I find was that the game is full of bugs!The most bad one is that this game is very very unstable.I get blue screen death everytime I get cannonballs firing at me from the DDs.What's more,when I am in the command room,I get very low FPS.So I want to know are there any mods or unofficial patches that will improve the game's performance and reduce the unstable factors?Please give me the recommandation and I'll be very grateful!Thx!
