I recently upgraded a Pentium IV 2ghz machine with 1GB ram running Giga2.54 (on Win98) to a Pentium IV 3ghz machine with 2GB ram and Giga3 (on WinXP).
Giga3 takes about 3 to 4 times as long to come up on the screen than did Giga 2.54!
I have WinXP configured for digital audio. This seems to bear out my opinion that no matter how fast the computers get, the software continues to make more and more demands on the hardware.
Has anyone else noticed that Giga3 loads much more slowly than 2?
