Ultra-low PPD triggered my attention. As I understand I'm not the only one with this type of new(?) anomalies: On Linux SMP only one of the processes is doing something, others are using 0% of the CPU.

Normal frame time ~10mins

Code: Select all

Yup this has been reported and they are aware of it. There isn't a single thread but a few scatterd around, I think they might got enough info on the bug to fix it and will likely only reply when the fix is there but that's just my assumption.

Thanks for reporting this, even if it's a known issue!
