If the driver decides to run the application on the When the display is connected to an IGP head, the NVIDIAĭriver decides if an application on that display should be rendered on When aĭisplay is connected to a GPU head, all rendering and compute on thatĭisplay happens on the NVIDIA GPU just like it would on a typicalĭiscrete system. Optimus systems all have an Intel IGP and an NVIDIA GPU.ĭisplay heads may be electrically connected to the IGP or the GPU. It is strongly recommended toįollow these guidelines to ensure CUDA applications are compatible with all notebooks This document provides guidance to CUDA developers and explains how NVIDIA CUDA APIs canīe used to query for GPU capabilities in Optimus systems. No proprietary hoops to jump through NVIDIA. Utilizing the PCI-Express bus to transfer the GPU’s output to the Intel IGP, there are The beauty of Optimus is that it leverages standard industry protocols and APIs to work.įrom relying on standard Microsoft APIs when communicating with the Intel IGP driver, to Powered off and the Intel IGP handles both rendering and display calls to conserve powerĪnd provide the highest possible battery life. When the user closes all applications that benefit from the GPU, the discrete GPU is In effect, the IGP is only being used as a simple displayĬontroller, resulting in a seamless, flicker-free experience with no need to reboot.
Using NVIDIA’s Optimus technology, when the discrete GPU is handling all the renderingĭuties, the final image output to the display is still handled by the Intel integrated The GPU, the GPU is powered up from an idle state and is given all rendering calls.

Also performance on nvidia is little better, but still after lauching youtube 1080p 60 fps video, it has less than 60 fps, i suspect it maybe has even less than 30. Now im trying optimus manager - it works but its a little rough - sometimes it works, sometimes i get black screen, and sometimes switching to nvidia results in strange position of manjaro "windows start menu" opening in the middle of two monitors. I first tried with egpu-switcher, and it switched nicely, but for some reason after reboot my system hangs up on messege "cannot start egpu-switcher service", and i had to use clean command to restore my original xorg files. Those two command lines write 2 monitors - my external and internal monitors, and 2 providers - nvidia and modeset (intel presumably?).
