Hello
ive been trying to get an older laptop to run traktor 2.6.3 by optimising windows 7 and using msconfig to minimise processes.I have been having issues with glitches cpu spikes in turn effecting audio.I have adjusted latency settings in asio4all which improved results slightly and then moved on to running gamebooster which appeared to lower the cpu load further(limited testing). I was unable to get sound working as a result.Anyone have any idea what may be causing this?
