I have intel(R) hd graphics 4000 in my system.
I want to upgrade my opengl version from current 3.0 to atleast 3.1
I tried to update to latest driver from device manager but it shows latest drivers are already installed.
I have also tried to download and install the latest driver from intel website. Still it is the same version.
I have been wasting hours and days on this.
Please also comment about clean installation.
