Disable the dedicated video card when it is not in use (see the #Power management section).

This bridge is provided by VirtualGL or primus (read further) and connects to a X server started for the discrete video card.

Render programs off-screen on the dedicated video card and display it on the screen using the integrated video card.

It has also been tested successfully with desktop machines with Intel integrated graphics and an nVidia dedicated graphics card.īumblebee is a software implementation comprising two parts: When the laptop is running on battery supply, the dedicated GPU is turned off to save power and prolong the battery life. The integrated GPU manages the display while the dedicated GPU manages the most demanding rendering and ships the work to the integrated GPU to be displayed. Optimus Technology is a hybrid graphics implementation without a hardware multiplexer. 5.23 Framerate drops to 1 FPS after a fixed period of time.5.22 Discrete card is silently activated when egl is requested by some application.

exe file), point to Run with graphics processor, and select the High-performance NVIDIA processor. To force an application to use your NVIDIA graphics, right-click its shortcut (or. You may find yourself loading up a demanding game (or other 3D-graphics-using application) and noticing poor performance – a sign that the game is using your integrated Intel graphics hardware.

While the NVIDIA graphics driver does a pretty good job of auto-detecting when the NVIDIA graphics are necessary, it isn’t perfect. Some laptops may have a BIOS option to disable the integrated graphics and use the NVIDIA graphics exclusively. If you left Steam open all the time, your battery life would be reduced because the NVIDIA graphics would remain powered on constantly. For example, Steam wants to remain running in the background, but, by default, the NVIDIA graphics stay powered on when it’s running. Some laptops may have an LED that lights up when the NVIDIA graphics is in use, so you can see whether the battery-draining NVIDIA graphics is running.īear in mind that you won’t see any benefits from Optimus if you leave applications that require the NVIDIA graphics running constantly.
