We want to do a performance test in our VDI. The VMs render more than 30 FPS, but only 30 FPS are encoded by Blast. We have tried many things, but there seems to be an FPS limit that we have not been able to turn off yet.
Our environment
Client
VMware Horizon Client 8.8.1
VM
Windows 10 Enterprise 21H2
VMware Horizon Agent 8.8
NVIDIA Guest driver 474.44
vGPU profile RTX8000P-3Q
Host
VMware ESXi, 7.0.3
2x AMD EPYC 9274F
2x Nvidia RTX8000P
What we have set so far:
- VM extended option
pciPassthru0.cfg.frame_rate_limiter=0 - in the registry of the Winidows 10 VM
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\VMware, Inc.\VMware Blast\Config
EncoderMaxFPS=60 (decimal)
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations
DWMFRAMEINTERVAL=15 (decimal)
However, the VMware performance tracker always shows only 30FPS. No matter what you set for EncoderMaxFPS.
Does anyone know the problem and how can we switch off this FPS limit?
