Just put a # infront of the entry for dtoverlay=vc4-kms-v3dīy default the OpenGL drivers are switched off as they are in testing and can cause problems with the graphics of the desktop and possibly use of the camera.īefore you activate the drivers install the graphics librarys with the command I would recommend you use a clean installation of Noobs while trying out OpenGL software as it allows you to easily edit the Config.txt file and deactivate the drivers if your display goes blank. To update and existing copy of Raspbian Jessie enter the following commands into Terminal: Noobs or the latest Raspbian image can be downloaded from here
This can either be downloaded from the Raspberry Pi foundation using the Noobs SD card installer or if you are running Raspbian Jessie you can upgrade your current installation to bring it up to date. To use the OpenGL drivers you will need the latest version of the Raspbian operating system. At the time of writing the drivers are still in beta testing but I thought I would try a few games and programs out from the Raspbian package list and see how they perform on the new Raspberry Pi 3. Both the Raspberry Pi 2 and 3 use quad core cpu's and have 1GB of memory allowing them to be more usable with OpenGL. Since the Raspberry PI was released in 2012 it has only had basic graphics driver support via the OpenGL ES drivers but many games and programs that require 3D hardware accelerated graphics use the full OpenGL drivers. Along with the release of the more powerful Raspberry Pi 3 I thought I will try out some existing OpenGL Games and software. It was announced in February 2016 that OpenGL drivers were being tested for the Raspberry PI allowing full 3D hardware graphics and a lot more Linux software to run on the RPi.
