    Sony Vaio Z2 PMD driver testing and investigation

    I have sony vaio Z2 with PMD, I have been wondering if there are any new graphic drivers for this model. Current drivers for Z2 are flawed when it comes to OpenGL and have features like rotation disabled by default. So any idea about other suitable drivers for me?

    This drivers are still under testing phase and not confirmed for use! Use it at your own risk!
    1. Download Driver Signature Enforcement Overrider .
    2. Disable UAC (Should be able to move the UAC slider all the way to the bottom. Can also be done by typing MSCONFIG in run and going to the Tools tab. You can re-enable it after installing the same way.)
    3. Run the Driver Signature Enforcement Overrider and choose "enable test mode"
    4. Reboot. (You should see Test Mode at the bottom right corner after reboot.)
    5. Run the Driver Signature Enforcement Overrider again and choose "Sign a System File"
    6. In the box type "C:\Windows\System32\drivers\atikmdag.sys" and click ok (do not include the quotes.)
    7. Click "Sign a System File" again and this time put "C:\Windows\System32\drivers\atikmpag.sys" (do not include the quotes.)
    8. Click "Sign a System File" again and this time put "C:\Windows\System32\drivers\igdkmd64.sys" (do not include the quotes.)
    9. Click "Sign a System File" again and this time put "C:\Windows\System32\drivers\igdpmd64.sys" (do not include the quotes.)
    10. Reboot
