Environmental effects

[Kruger]

Since my game was stuttering a lot in fog, I disabled the environmental effects. Good....the game looks very nice and runs smoothly now. But...I've lost water transparency, I no longer see my boat under the waves. Is there a way to get rid of the volumetric fog but keep the water effects ?>

[SAMiV]

I'd like to know answer for this one too.
I also wonder, that would it be possible for the devs to add extra option, so that you can seperately turn the fog and transparent water on or off.

[Hartmann]

Yes, could be very interesting extra options.

perhaps when sh3 hex edit genius and modders look into game files and can discover about change water transparency or other graphic options.

[PeriscopeDepth]

Yeah, I wish they seperated the fog and water transparency too, but currently it's either both or none. I wonder which is more of a performance hit, fog or transparent water?

PD

[GoldenEagle8]

What are the chances of that sort of opotion being in the next patch?

(slim to none?)

Guys test something please ,'cos I think this makes the fog disappear.

The fog is gone but it need testing.

I tested this code and the fog wasn't visible anymore. BUT, I am curious whether the fog is simply not visible but still calculated by the hardware, therefore offering no benefit, or is it truly off.
I think that the DEVs might be in a better position to implement this properly.

What I did notice with the fog off, were the lightshafts now visible in the atmospehere.
I guess the lightshafts interact with the fog to give it more realistic look.

Ideally we would want to disable the lightshafts (ABOVE water and NOT under the water) along with the fog. Or perhaps only the shafts above the water and leave the fog on.

There is separate code for the shafts above and below the surface, so it makes sense that it may be disabled separately.

Just a few more display options in the menu.

I had to shut it off too and it sucks. Some kind of bug where your framerates drop to 1 if you look at a certain spot. Some people have taken pictures of these so called spots and something is not right.

[DJSatane]

Well, I hope you guys also know about the bug related to environmental effects that is displayed in detail in this thread:

http://www.subsim.com/radioroom/showthread.php?t=108938

I am curious whether that bug still occurs when you disable just the fog.

What we would really want is to fix that mysterious polygon that appears with Environmental effects on and kills fps, maybe removing some routines while still having water transparency is possible.
