Lighting performance in firefox

[grapereader]

Lighting performance is abysmal in Firefox (10-15 FPS), but perfectly fine in Chrome (50-60 FPS).

Weird shit.

Doing some profiling. It looks like the current configuration creates a TON of shaders. That might be part of the cause.
Firefox doesn't have shader caching, so it's compiling these shaders every time it creates one.
Very bad.

Solution. Render everything to two RenderTextures.
One with the diffuse, and another with the normals.
Then we put the filter on the diffuse render texture and render it to the canvas. Should reduce all those shaders to 1.

This does work, and it reduces the shaders to 1.

However, this is actually at a detriment to performance. So scrap that idea.

Looks like it might have something to do with my system configuration.

Tested on another computer with good performance.

Tested it on my own computer with a spoofed system configuration and performance was much better.

Obviously due to this:

Nothing I can due but try to make lighting more efficient, or make a lighting fallback that isn't so OpenGL intensive.
