[opensource-dev] Basic Shaders and FPS

[Lee ponzu]

This is something I just discovered that I suppose most of you have always
known.

I was messing with my oldish iMac (ATI 2600 Pro) and I discovered that the
main thing that makes all the difference to FPS is the shaders.

Basic Shaders off:  FPS == 30 to 50.
Basic Shaders on:  FPS == 13 to 15

Similar effect for just Atmospheric or Shadows.

So, this made me crave a custom button for turning shaders on and off (yeah,
CMD-P/Graphics/Basic Shader is easy.  Just thinking of all the people who
don't even know that preferences exists  8-)  Need FPS?  <<click off>>.
 Want things to look better?  <<click on>>  Easy peasy.

BTW, I also briefly tested on my slightly newer Macbook Pro (nvidia 9400M).
Same ting, but the FPS difference is much less dramatic.
