Hi! I'm just curious about how your ANUS-DAW is running with Cubase SX. I've found a link to this test file in a swedish forum: CubaseSXTest When I did it my CPU-load was ~52%. It would be interesting to see how your system is doing? I guess that Master Opus will probably win this test! Well this is my system: Asus P4B533-V Mobo Intel P4 2.4 GHz 533MHz 512 Mb Samsung DDR PC2700 WD 120 GB AudioDrive WD 120 GB OS-drive Matrox G550 videocard Win XP-Pro RME-Hammerfall LE soundcard Cubase SX Finally , I did 95% of the "Opus-Tweaks". It would be fun to see how different systems are doing in this test.
