[quote=Hartmann]I donīt know about seagulls but i know how remove the placton, the rocks,plants, and the water moving distortion

but i am not sure if it improve famerates.
remove or move to another folder :
placton: misc/impurity.dds
Water distortion: misc/turbulence.dds and underwater_disp_map.dds
Plants and rocks: library\undersea.dat and vegetation_kit.dat
it helps to have a nice and clear screenshots of underwater views, here is one but with underwater rocks
Could be interesting resize the rocks and plants , because are too big and donīt have collition detection. the sub pass through the rocks
In my 2200+ ,Gf6600 gt , 1 gb ddr400 i have between 15 and 25 frames in the navigation mission depending of the view. not very good performance but enough to see the game.
Itīs a sligh better in open waters
Here we can see that the limitating factor in frame rates is the graphic card , no the cpu and memory.:hmm:
