RadeonX1600

    I am working through the shader tutorials and wonder whether the X1600 GPU in my Intel MacBook is one that supports programmable shaders.

      Definitely. That's a nice one. Any GPU made in the last 3-2 years will support shaders.

      Hi i've got the Radeon x1400 graphics card, and it seems that some shaders don't work properly from the tutorials. I thought this was due to my graphics card, but Wesley's statement that "Any GPU made in the last 3-2 years will support shaders." assumes that there is no gradation in enabling shader functionality. ... what i was wondering is exactly that: if shaders are *enabled* than all shaders should work? is that so? if not, how can one determine what a gpu will deliver?

      Shaders are limited by the hardware of the graphucs card and the drivers running them. Some GPUs have higher instruction counts than others so they can run more complex shaders that older graphics cards might not be able to.

      Try it out. The compiler will optimixe things a bit, so it can be hard to say if a certain piece of code will run or not if it's a borderline case.
      I'm using pretty much the same GPU as you (x1600). I've yet to have a problem with a jitter shader (except for the rota shader which was resolved). What shaders are giving you trouble? Post a patch. It's better than speculating.

      does anyone have experience with the macbook 2.16ghz and 128 megs vram vs. the 2.33 with 256mb? does the extra vram pay? i think i once heard that macs with extra 256 mgs vram get even slower due to addressing problems.
      i work a lot with opengl, so i assume the 256mb makes really sense for me...?
