Intel's new open-source OpenGL Linux driver "Iris" Gallium3D that has been in development for the past two years or so is getting ready to enter the limelight. Months ago they talked of plans to have it ready to become their default OpenGL driver by the end of the calendar year and with the state of Mesa 19.2 it's looking like that goal can be realized in time. With our new tests of this driver, in most games and other graphics applications the performance of this Gallium3D driver is now beyond that of their "classic" i965 Mesa driver.
