Volume control and CPU

cPlay's digital VC offers 53 bit resolution (64 bit double precision) throughout. I use this as my main VC over dCS' Scarlatti DAC (digital VC). In your case, I would test which VC to go with, but definitely avoid using both (i.e. one of them should be at full volume). If your DAC does digital VC, use cPlay instead.

CPU load definitely changes a little although same amount of MACs (Multiply Add Computations) are done. Best option is SSE4 when your CPU offers it as this employs a key CPU instruction in the most critical area of cPlay.

Shared memory (34MB) on mobo can be lowered - check your BIOS under video setting ("On-chip Frame Buffer Size") under "Advanced BIOS Features" (I think) and set to 8MB (note: do NOT use the lowest 1MB option).
