Live 10 CPU Spike With New (to me) Hardware

Post by BiasPly » Sat Nov 19, 2022 4:24 pm

Hello,
I just built what I thought would be a great Live 10 workstation.

Here's the rig that was stable (but underpowered):
ASUS Vivobook laptop, i7-7700HQ, 16Gb RAM, Windows 10 Home (21H2), Geforce GTX1050.
FOCUSRITE Scarlett 18i20 2nd Gen
UAD Apollo Twin USB (only used for DSP)

Here's the new one:
Z600 with dual Xeon E5620 (8-cores total), 32Gb RAM, Windows 10 Pro 921H2), NVIDIA NVS 310, PCI USB 3.0 card.
UAD Apollo Twin USB (same one) - using for both DSP and as the Audio card.

I load up one of my projects that would be about 60-70% CPU on the stable rig, and it totally kacks out on the new one, 110+% CPU. No matter how I adjust the buffers for latency. All drivers are up to date.
For more weirdness, Reaper runs totally smooth on the new one.

I would really like to keep using Live 10 for the clip grid ability for live performance as I use an APC40 and Launchpad mini to trigger clips and do live dub mixing. There is really no other option out there that works as well.

Does anyone have any ideas? I did try using dummy audio, ASIO4ALL, and other ways to bypass the UAD device, so while sure there may be an issue with the PCI USB 3.0 card, that isn;t the whole deal here.

On paper this should rock.

Thanks in advance for any help here.
CHeers,
STeve.
