Hi Erix,
did you solved your Problem regarding the bad latency…?
I come from ESI Juli@ (pci-card) with 5 ms global latency (48 Khz & 128 Samples; input: 2.67 ms, output: 2.67ms).
The UR22MK2 shows global latency of 13.9 ms (!) (48 Khz, 128 Samples; input: 6.48ms, output 7.48ms)
on my Intel i7 8700k (Gigabyte z370 hd3p) 16GB ram, Windows 10.
UR22MK2 Firmware: 1.04
Driver: 1.10.4
Windows 10: 1903
With 48kHz and 64 Samples i got 4.125 input and 5.125 output latency - global: 9.25ms latency
Strange: On my old Macbook pro (late 2013; i7 8GB RAM; Mojave) the ur22 (48 Khz, 128 samples) has 10.7 ms (input 5.23, output 5.46 ms).
It is better than my newer i7 8700k !
What i have done to reduce the latecy-values:
–> i already unplugged all usb devices, reinstalled yamaha drivers, the ur22mk2 got the newest firmware.
–> i already unplugged by PCI Card (ESI Juli@) to see what happen. But it didnt change the latency of my UR22MK2
–> i turned off “Intel Turbo Boost” in my BIOS.
–> my Windows is running in “high performance” mode.
–> i updated my Chipset driver, usb driver, nvidia driver are uptodate
–> i disabled onboard sound
–> i disabled onboard graphic card.
–> i unplugged my GTX 1080 graphics card and tried with the internal onboard graphics card
–> i have the newest BIOS Firmware (Motherboard) F13
… the “bad” latency values are still there - nothing of my actions (above) leads to better values.
I have no idea why the UR22MK2 has “bad” latency in compare to others or in compare to my old macbook…
I know a pci audio device like ESI Juli@ is even better in latency because usb is more laggy but 13.9 ms… on actual hardware (i7…)…???
I will now test with an old core2duo HP Notebook to see whats up there…
The results:
(48Khz, 128 Samples, core2duo on Windows 10)
Input 6.7 ms
Output 7.7 ms
So the poor latency values seems to be a problem of UR22MK2 with Windows 10…
