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?
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.
