Hi,
Cubase Pro 9 to 10.5.20 all have this kind of issue.
Windows 10 64bit 1709, 32g ram, i7 4790k, avid version duet
(I have tried all later version of windows 10 except 2004. There all have huge performance impact on 4790k. So I went back to 1709)
There are pops and cracklings while playback. If I disable the first 2 cores of cpu, it’s gone, everything runs smoothly.
If I load some large sample based instrument, the input latency sores.
asio buffer____output latency____input latency before loading____input latency after loading____delta of input latency
64___________3.039____________3.016________________________7.211______________________4.195
256__________7.392____________7.370________________________11.565_____________________4.195
512__________13.197___________13.175_______________________17.370_____________________4.195
The heap / jump / increasement (I don’t which word is properly) of latency time is a constant value under all buffer size settings, and it varies every times, around 3 to 5ms. It lasts about 1 hour before the latency returns to normal. Or I can restart the computer to eliminate it.
But, if the first 2 cores of cpu are disabled before libraries loading, all the issue disappears.
What I have done to try to solve it:
Create new power plan
Reinstall audio interface driver
Disable services about storage
Uninstall steinberg generic asio driver
Disable energy saving on both windows and bios
Update acpi driver
Thanks in advance.
Sorry for my English.
