When playing a file in (for example) WaveLab, the machine uses up to 99% CPU. As a result (?) I have these 'drop outs'. When I put the WaveLab-window in the taskbar, the CPU usage drops to around 20%. It seems the videocard uses far too much of the CPU, is my conclusion.. The same problem appears when using Cubase... This is on a 1.7ghz Compaq, 768 ram, and a 64mb NVidia Gforce 400mx videocard. Using a Motu 828 FireWire audio interface. It runs WindowXP, and I am a mac-man myself. Tips anyone? thx.
