Blast Lag / High GPU usage

ntripp13 — Thu, 13 Feb 2020 19:45:03 GMT

Testing out a new host in our VDI on Epyc for some demanding users. Vm Spec: 32 cores (carved out of an Epyc with 4 total user, there is no over subscription of cores), 64GB of memory, T4 using a 2Q profile. 3 screens: 2x @ 2560x1440 and 1x 3440x1440.

I'm seeing that the GPU is often close to 100% by the Blast process while cpu is minimal. The lag feeling is present even typing in Outlook. I did try turning on H.264 and the GPu utilization went down but the lag between clicks and things like that is painful.

What's the deal? I'm on Horizon 7.8

Can I ask what content is being rendered in the active Chrome windows consuming 6GB of RAM? If they're streaming a full screen video at the resolutions of the monitors you've said are attached, it's unsurprising that the GPU is being heavily taxed.

Thanks
