Shaders under OSX

[thelusiv]

I'm not sure if I can add much to the shaders discussion, because I know almost nothing about them. However it strikes me that in your screenshots some of the fonts are off. It looks as if a different font is being used than the one we include for framerate, lap counter, and the numbers on the face of the tachometer. What's up with that?

Joe tends to leave a lot of comments behind when he codes, and I've cleaned up a ton of them for him in VDrift before, it's no big deal.

I'm interested in the cleanup work you've done on the shaders - I think we (Joe & I) as coders tend to think of unrolling loops and other kinds of optimization is best left up to the compiler - but maybe this kind of thing doesn't apply to shaders. (Again I'm more or less ignorant on the subject of shaders...)

In other threads discussing OS X issues with graphics, and falling back on software rendering, it has been mentioned that there are still problems with OS X's implementation of OpenGL 2.0. Are you sure the problems lie within the shader code and not within OS X? (More grains of salt with reading this: I don't have any Apple machines...)
