[question] Viewport is unresponsive if bigger than full hd, Does 4k 60fps is achievable ?

[erinorina]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

The blender viewport is responsive at full hd resolution, but not in 4k on localhost,
I would like to understand if i miss-configured my launch parameters, or if it's a limitation of KASMvnc.
cuda , optix, work fine in the container.

My HOST hardware :

NVIDIA RTX 3060 Driver Version: 525.147.05 CUDA Version: 12.0

$ xdpyinfo | grep -i "DRI"
    DRI2
    DRI3

In the Container:
I am not sure if it's relevant, but i noticed xdpyinfo | grep -i "DRI" return nothing

Kasmvnc limitation, you might want to try lossless if you have a bunch of spare CPU threads. It is still VNC, turbocharged VNC with more broad image format support but it is not a video codec.

Thank's , sorry i overlook the cpu usage, 24 threads at 2.50GHz are not enough (XeonCPU E5-2678 v3),
I will look into another protocol that use GPU encode/decode (moonlight/sunshine) which use nvenc.
