Spring RTS Engine

fog, as seen on "hexfarm" map or with the gadget in blueprint, causes bad fps drop for me. When it is enabled fps are ~15, without fog it is 100.

When zoomed out there are line artefacts across the map:

and in zero-K, the commander-selection menu takes multi seconds to load the pictures. (see pic: game running since 4s but no pictures show yet, also bugged res bar) Not sure if that is caused by fog or simply by low fps.

yesyes card sucks.
But since some other players seem to have that problem too, maybe in blueprint fog mapoption should default to off instead of on.

Disable luashaders support in springsettings.

other luashader things work fine though.
for example in zk: "units on fire" and napalm, lups, that shockwave/distortion effect, transparent cloaking units

fog fps problem is really sad. a beautiful and interesting map like "seths revine" is almost never played bc there is _always_ a player for whom it is impossible, and very few know the name of the setting to switch the fog off.

In related topic - fixed seths ravine fog?

HexFarm, ok, but blueprint too, sure? Because I've been told to fix HexFarm's fog's lag by replacing it by blueprint reference implementation.

yes.
same map+mod, toggle fog: with fog on it lags.
imo because of that fog should not be def = true, in mapblueprint, or nubs will make lagmaps!

Is there a way for the Lua to autodetect that fog will cause lag?
