PT 2020.11 CPU Spikes with eGPU at low buffer

[nebosphere]

Hi All,

Has anyone seen this issue yet? I get frequent 9093 errors at low buffers (128 and 64) in this new version and I believe I've traced it down to mouse/trackpad pointer motion. It only happens when my eGPU is attached. It's easily reproducible even without a session open. Look at the System Usage window and wiggle the mouse a few times and you should see spikes. If you are playing back audio, it will stop with a 9093. If I use integrated graphics, it does not happen.

I'm wondering if anyone else has a similar rig and can comment:

Mac mini 2018/2020 i7, 64GB RAM, 2TB SSD, Sonnet eGFX 550 with Sapphire 5600 XT eGPU (4k monitor), PT Ultimate 2020.11 HDX, UAD OCTO PCIe running in a Sonnet Echo Express IIID (TB2->TB3).

Each Sonnet box is on a separate TB3 bus. I've tried this already, to no avail: https://avid.secure.force.com/pkb/ar...-Errors-on-Mac. Have a ticket open with Sonnet as well.

Update: happens in native or hdx mode and when all but the eGPU are disconnected

Would love to hear from anyone using Pro Tools 202.11 with an eGPU!
