which version ?wushuliu wrote:Hi, I have just installed MQN on an AMD PC. I've been using Jplay for a longtime and have to agree - after changing Win32 Separation to 28 MQN soundsMUCH better.

now MQn 2.5x, 2.6x has gotten so much more revealing, 18 starts to be inappropriate. i now believe 28 is best. 18 was forcing the details. 18 was good because MQn was lacking details relative to now.
18 losses some layers of bass and adds earaches and losses some musicality.
in a high digital jitter environment, meaning, OS is un-tuned, 18 is better. in a highly tuned OS+2.6x/2.5x MQn, 28 is better.
of course there is 14 recommended by jplay. all it does is make stage sounds 'better' in exchange for musicality and many details. i dislike it.
yes, via registry
been playing around with clockrate + Win32PrioritySeparation + timer resolution all week. i have finalized the best combination for MQn, XA and lekt under 44100. the answer is:wushuliu wrote:Hi, I have just installed MQN on an AMD PC.

18/46440 for me, what is timer resolution ?jesuscheung wrote:been playing around with clockrate + Win32PrioritySeparation + timer resolution all week. i have finalized the best combination for MQn, XA and lekt under 44100. the answer is:wushuliu wrote:Hi, I have just installed MQN on an AMD PC.

clockrate = 5805
Win32PrioritySeparation = 28
timer resolution = 1 or 2
1 clockrate rules all!
might not work for everyone. DAC may or may not be a variable too. not sure.
this is not the most 'hard working setting'. the hardest working settings would have a 6 digits clockrate that is too accurate, with Win32PrioritySeparation=18 to tell OS to try harder, and timer resolution=0.5 to tell the OS to try even harder. my machine can't handle such 'pressure', SQ is not musical using the most 'pushing' settings.
win 8 has a tickless kernel and the timer resolution can be set just for one process without affecting the whole system, shall investigate if it makes a difference for MQn. There is evidence that setting it to 0.5 or 1 etc actually makes the system run slower as the timer irq is firing all the time.jesuscheung wrote:this is not the most 'hard working setting'. the hardest working settings would have a 6 digits clockrate that is too accurate, with Win32PrioritySeparation=18 to tell OS to try harder, and timer resolution=0.5 to tell the OS to try even harder. my machine can't handle such 'pressure', SQ is not musical using the most 'pushing' settings.
yes 0.5 can be bad. can be too aggressive. it can crash my mySQL server when flooded with connections at the same time.sbgk wrote:win 8 has a tickless kernel and the timer resolution can be set just for one process without affecting the whole system, shall investigate if it makes a difference for MQn.
