prime-run not using my hybrid gpu

[picarica]

so hello i started using laptopt recently for my gentoo, my first time laptopt i have some issues using that dedictated nvidia gpu
i red this guide
file:///usr/share/doc/nvidia-drivers-550.90.07/html/primerenderoffload.html
didnt helped, even with their command the vkcude still runs on 100% cpu

i tried

In MUXless systems, you cant use your dGPU for direct output. You should only use PRIME Render Offload on games and apps that requires dGPU acceleration. Use iGPU on KDE, most times only option is iGPU. You can force Vulkan by "__VK_LAYER_NV_optimus=NVIDIA_only" variable.

As i said you can't get direct output from your NVIDIA GPU, you have to use iGPU as always. First remove "__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia" if you declared those as constant environmental variable. Don't use those while running any program except you need OpenGL and Vulkan like games. Also don't use any of prime-run or bumblebee stuff, they are abandoned and unmaintained. NVIDIA's own PRIME Render Offload is works best in performance and compatibility both. In Blender, you can select any CUDA device(your NVIDIA GPU) in Preferences > System tab, it actually accelerates your workflow. You can select NVENC in OBS or any program that supports NVENC or NVDEC without PRIME Render Offload. CUDA and NVENC/NVDEC are indepentent from PRIME Render Offload, you can use them. "__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia __VK_LAYER_NV_optimus=NVIDIA_only" is only should be used on OpenGL and Vulkan output if required. It may wont work or work but not as expected on Wayland, you should use without problems in XWayland or Native X applications.

You have to enable "cuda" USE flag for using GPU acceleration on Blender.
