Update on Q3 and Altivec
9:13 AM | Andy Largent | Comment on this story
Wednesday id Software's Graeme Devine made a post to the Quake3World forums regarding some enhancements he was making to the Mac version of Quake 3: Arena. Specifically, he was working on Altivec instructions which should give G4 owners a significant boost. Here's his first post on the subject:
I finally got around to programming in Altivec support for Quake3 1.27h. If you have a G4 you'll certainly want to flex that velocity engine! I think this safely puts the G4 ahead of the PC. I'll probably post this tomorrow.He mentioned he might have something available as early as Thursday, though now it looks like the update will be delayed in order to do some more tweaking. Here's his second post:
We have in the office a G4/533 with a GeForce2 card. It's a very very nice setup.
Still working away on it. I've been encouraged to add more than a sprinkling of altivec operations into the code, so I'm about half way through with a larger overhaul. I'll carry on.We're sure Mac G4 owners will be willing to wait in order to get even more optimizations in the code. On a related note, if you haven't already, check out our Macworld stories regarding framerates for Q3A and the new G4 towers. Considering they were running a pre-Altivec version of Q3A, these numbers could improve even more. We'll let you know once a new patch with the Altivec code is finally released.
