If i change from q35 to i440fx the latency goes away. And the latency generates audio dropouts. I am training to use this vm as an audio workstation. Is there a way of mitigating the latency spikes?

#HIGH DEFINITION AUDIO BUS DRIVER WINDOWS 10 LATENCY DRIVERS#
I have tried switching all my drivers to MSI (graphics card especially) but with no positive effect. Proxmox, as well as my VM are on the same SSD (Crucial MX300 525GB, 3% wear). Also, when using LatencyMon, I have considerable ISR and DPC execution times (in the order of 3-10 ms max.). It is using 14 of the 16 threads that a Ryprovides and also 20 of 32 GB of total RAM.Īnyway, when used for gaming, I get noticable spikes every 30 or so seconds.
