IRIX and Software

I found this in SGI techpub. Looks like this is customized script from SGI that will allow Photoshop to run faster on SGI hardware. Wonder if anyone knows about this?

I remember seeing that a few years ago. I can't remember if it was O2-only though - I seem to recall that it was limited in what graphics hw could run the photoshop accelerators.

It's actually included by default in most IRIX 6.5 installations - apparently it accelerates functions like gaussian blur and whatnot. It's easy to implement: from a command line, after installing and running Photoshop once, you execute "photoshop_sgi -update" and then launch Photoshop via the "Photoshop_SGI" icon in the catalog. I've never benchmarked to compare the speed difference.

iirc there was an additional enhancement for the o2 in particular. not sure what it did exactly

I think it was similar to the DSP accelerator products for other architectures in that certain plugins/ops were sent to ICE.
