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

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

... what i was wondering is exactly that: if shaders are *enabled* than all

is that so? if not, how can one determine what a gpu will deliver?

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

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

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

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 

i work a lot with opengl, so i assume the 256mb makes really sense

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...?
