GRID VGPU and Blender compatibility

I am using the nvidia grid VGPU (RTX6000) on the Exsi 7.0 hypervisor. However, blender and a dose of OpenGL software such as Rviz and Cloudcompare do not seem to work properly with the VGPU. All these applications only use the SVGA device. I have tried disabling the SVGA device in the VM setting, but that doesn’t make a difference. nvidia-smi shows that even teamviewer is using the GPU in this setting, but not other applications. However, UE4 works smoothly. What might be the causes? thanks for any tips! Merry Xmas!
