ASIO Performance Spikes in Artist 8.5.20 - Help
Postby Seeker_UK » Tue Mar 07, 2017 10:41 pm
The title says it all really.
Running a Dell Optiplex 780 (latest bios - A18), 4GB RAM, i7 (2600) 3.4GHz processor, Sapphire AMD Radeon HD 5450 1GB, Focusrite Saffire 2i4 2nd Gen.
I had 8.5.20 (32-Bit) working perfectly until recently. Now at some random time, typically 2-3 minutes the CPU average hits 100% and causes a dropout, even if it’s running at 20-30%. DPC Latency Mon and Latency Check shows no issues for processors but occasional page file faults but nothing to suggest any issues.
Having read many threads on this, I have:
Switched off power saving in BIOS.
Disabled c-states in BIOS
Changed power settings to highest performance (ie no hibernation / sleeping) but have not used Steinberg Power Scheme.
Changed the NVidia video card for the Radeon and installed latest driver - only driver was installed, no other software.
Changed an Alesis io|2 for the Focusrite with latest drivers (4.15) installed.
Ensured the USB mouse and Focusrite are on difference USB hubs.
Updated the NIC driver to latest from Intel site (cured the spike every 4s observed on DPC Monitor)
Updated the USB drivers to latest Intel drivers.
Tried Cubase with ASIO guard on and off.
Tried ASIO4ALL, Generic ASIO and Focusrite ASIO Drivers.
Nothing seems to make any difference and I can’t see a link between a particular activity or plugin(s) used and causing the spike - it happens regardless of the amount of tracks / plugins used.
The only things I can think of that are left to try are a complete reinstall (I’d rather not), install a USB 3.0 adaptor card for the Focusrite, roll back to Windows 7, buy a new PC or finish with Cubase.
This was reported to Steinberg tech support on 8th March - no response yet, not even an acknowledgement.
I installed the 64 bit version but kept it at 8.5. Exactly the same symptoms.
I’ve updated to 32 bit 8.5.30 and that hasn’t sorted it.
I’ve kept the mouse and Focusrite on separate USB ports.
Run Latencymon and everything is OK.
Please, can anyone advise what else to try; I can’t make music anymore.
