Prime render offload. PRIME GPU Render Offloading/GPU on-demand Mode Guide: Our notebooks usually have a battery-saving iGPU and a powerful but also power-hungry dGPU. Jun 16, 2025 · The NV_PRIME_RENDER_OFFLOAD environment variable causes the special Vulkan layer VK_LAYER_NV_optimus to be loaded. I tried doing the same thing in windows, and had the same result. Oct 26, 2023 · Fortunately, NVIDIA provides an easy way to offload rendering to the dedicated GPU using the environment variables __NV_PRIME_RENDER_OFFLOAD and __GLX_VENDOR_LIBRARY_NAME. This technology is seen in laptops, as they'll typically have both an Intel Integrated solution AND a Nvidia Discrete solution. You can now run the entire system on one or the other GPU, depending on what you need. The command xrandr --setprovideroffloadsink provider sink can be used to make a render offload provider send its output to the sink provider (the provider which has a display connected). . Prime Render Offloading pretty much allows your system to offload the rendering to a discrete GPU (which is Nvidia branded). PRIME render offload is the ability to have an X screen rendered by one GPU, but choose certain applications within that X screen to be rendered on a different GPU. My theory is there is some overhead with prime offload that depends on resolution, and even though you are rendering on an NVIDIA GPU, it was causing the AMD card to also hit 99% utilization. This is particularly useful in combination with dynamic power management to leave an NVIDIA GPU powered off, except when it is needed to render select performance-sensitive PRIME GPU offloading We want to render applications on the more powerful card and send the result to the card which has display connected. The smaller I made the window, the more frames I would get. Vulkan applications use the Vulkan API to enumerate the GPUs in the system and select which GPU to use; most Vulkan applications will use the first GPU reported by Vulkan. knpt tgkrhn rql aawmd fwnd irbua mwge eoacc jupvw mrpd
