Cavitation speeds?

Pillar · 08-22-09, 07:19 AM

These subs appear to be always cavitating at all speeds in external view. Are the graphics telling the truth? When does cavitation kick in and does the game take it into account? Also, when stationary with "all stop", is it true to life that the props kept spinning?

Eyecandy: the graphics effects you see which have no bearing on real game behavior. This includes fake cavitation, wavy underwater view, visual damage, sub skins, where do I go from here?

It is a grave mistake to confuse eyecandy for game mechanics. For instance, your sub can have a visually large hole in its side and still submerge, possibly with a small hull damage percentage!

A target can have no visible damage and sink like a stone, or lots of it and never sink at all. A real underwater view is like looking through air, there is normally no image movement as rendered in the game. We have lots of graphical curiosities, none of which have any impact on gameplay at all.

Ok, good news

When does cavitation kick in for the game engine rather than just the graphics? Is it significant like it is with modern subs or are these boats noisy enough that cavitation isn't half their problem?

I don't believe that cavitation is modeled at all.

I agree with RR there, cavitation isn't modeled in the game at all. But in real life cavitation is a concern for all ships, past and present. Cavitation can physically damage a ships screw to a point that it becomes less efficient.

Good to know, thanks mates.
