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
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…
(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…
