JC Audiophile optimization on win7, 2012, and R2.

I can confirm JC's buffer/timerresolution combination is very good.

Buffer of 8 ms and timerresolution of 20000 (actual 20001) is a very relaxed beautifull and natural sound with a lot of warmth, detail and air.

BTW my registry clockrate is 464400. MQn version is 2.70

there is no restriction. pick any buffer you like is divisible by 0.5, 1, or/and 2ms.

i choose 8ms (actually is 0.798...) because in ASIO4ALL the best selectable buffer is 352.
for example, there is no 441 to select in ASIO4ALL. 441/44100 would have rounded to perfect 10ms.

I wil certainly experiment some more, but not all sound equal.
E.g. 1 ms buffer and 10000 timerresolution sounds more strained.

Of course a myriad of combinations is possible this way, but I do like your combination.

pkshan has buffer=640=14.5ms using timer resoluion=0.5ms on his audiofire.

i used to have that settings. doesn't work best for my DAC STX. now i have 352/8ms+2ms/1ms, i am very happy

XA has updated Windows7 DAW 1.1. i have just installed it. previous version 1.0 was giving me a lot of earaches. this version is absolutely beautiful. my optimized R2 is far from that level of SQ. all players lekt, MQn, XA sound wondering.

this OS is weird. takes time to 'burn-in'. think it is because VS2013 installs .net that runs '.NET optimization services" in the background for hours until it finishes on my i7. this is OS is so easy to tweak, just do whatever he says on his blog, SQ will increase. just don't do his Aero optimization and don't install any graphic driver.

i have my own tweaks to apply on this 7, but i am afraid i would ruin the sound. need to ghost it.

----BAD TWEAK NUMBER 1---

changing IRQ for different drivers at registry:
HLM\SYSTEM\CurrentControlSet\Control\PriorityControl

1. decreasing priority of graphic card
sound is sharper. lost of warmth and mellowness.

2. increasing DAC priority
sound gets intense not free. same effect of minimizing buffer size of player.

3. increasing clock priority
seems better clarity. sound is distorted.

can't find a IRQ tweak that works.

[jesuscheung]

alright. XA's 7 is good. more correct than 2012. i still like my R1 better.

R1>7>R2

my R1 is super airy due to perfect drivers combo. after i perfected my clockrate, i reassessed and upgraded my CPU/RAM frequency and timing and voltages, also updated my DAC audio output settings, and now i don't find R2 better clarity than R1 anymore.

R1 it is. peace and love.

if anyone needs to 'measure' how optimized their OS is, download "DPC Latency Checker".

my R1 and R2 latencies are both:
1 to 2us.
average 1us when playing MQn. some random spikes to 6-7us.

AFAIK dpc latency checker doesn't report proper values from Win8 onwards.
Still has to be fixed.

Only LatencyMon from Resplendence.com is suitable for win8 onwards

don't agree. when i didn't disable dynamic tick, the treble was horrible, dpc correctly reports 1000us. before optimization, my latency was about 50. after optimization, my latency is 1us. how is this incorrect?

alright, right now, listening to MQn, using chrome, LatencyMon reports average of 5-10us and peaks at 84us. is this good?

you right, LatencyMon is more accurate.

Where could I download his DAW 1.1? Thanks.

P.S. I can not install VS2013 on my 2012 server as it wants IE10 to be in system.
