Goblinz/playboss: asio4all is just a wrapper, so that WDM drivers can be used in asio apps... Because it still uses the normal WDM drivers and adds ASIO 'on top', it may, in some circumstances, decrease soundcard latency, and will, always, increase CPU consumption, because it's doing more work. So it'll "speed up" your audio and otherwise "slow down" your PC. So you're both right, and you're arguing over poorly applied terminology. Now go and kiss and make up. ;D
