DFG/1394-1 3.0 Drivers

I just recently brought a DFG/1394-1 and still need to buy drivers from Aupperle. But just looking at the site it mentions the 3.0 release does not perform as well.

Has anyone had any experience with the new drivers? Any performance issues?

From: http://www.outcastsoft.com/ASCDFG1394.html

There seems to be a performance difference between the older 2.06 DFG Driver and the new 3.0 Universal DFG Driver when used on PowerPC Macs. The new 3.0 driver has higher CPU usage than the old one does. Why??
This is because the 2.06 version and earlier were all built using the CodeWarrior development environment and the 3.0 version HAD to be built with Apple’s XCode (we have no choice but to comply and be assimilated). Apple’s XCode generates very poorly optimized Altivec code which executes 30 to 40% slower than the same code compiled with CodeWarrior. Note that many developers have reported similar slow downs and in our own in house testing, we have some internal cases where XCode generates Altivec code that runs 100% slower than CodeWarrior does. We can’t help but wonder what performance differences one would get if OS X had been compiled using CodeWarrior, especially any of their Altivec specific code.

I just got the new driver for my macbook pro, and though I haven’t had
the opportunity to really put it through it’s paces, it seemed to work
adequately well.

As I understand it, if you’re still on PPC, the previous version will
work better for you.

Yeah, sounds like the safe bet. But the eventual purchase of a IntelMac looms….

It sounds like you didn’t notice any difference at any rate?
Certainly not in terms of lag / latency?

from my understanding, you only begin to see a real difference when
using more than 3 daisy-chained dfg boxes at once (so says the
driver’s creator, in an older email exchange with me).
