Texture access spped

Hi
I don’t find any information about texture access in fragment program. I know it’s slow, but i would be interested to have execution time for different arb fragment instruction (and especially TEX).
Any idea where I can find that?
Thanks

You can’t get a exact answer on how much a TEX call costs. Firstly this depends on your graphics card and secondly this depends on your shader. For example if you have a quite long shader and a view TEX calls then the arithmetic instructions hide the latencies of your TEX call.

Supposedly it also depends on the cache coherence of your texture lookups.
