Hello,
I just recently got my T100TAF, and one of the first I wanted to do was to install the latest Intel graphics drivers. I came across the 'standard' issue most of you probably have experienced - after downloading the correct drivers and trying to install them, an error message pops up, something like 'This driver is not compatible, install the one from your pc manufacturer.'
Well, that wasn't enough for me, as there are no graphics drivers available on the Asus website, so I decided to do some research. Googling for the error message got me to the intel website, explaining that I should not, but if I want to I can uninstall the original driver and then be able to install the Intel one. So I did, and now have updated driver, which seems to be working without any issues.
You can get the latest drivers here: Intel.
The driver version I got by this method is: 10.18.10.4276, dated 17/08/2015.
Steps:
1. Download the driver from the link above.
2. Turn off automatic driver installation (Search for 'Change device installation settings', choose 'No, let me choose what to do', 'Never install...', Save changes).
3. Uninstall the display driver (Search for 'Device manager', find 'Display adapters', right click 'Intel(R) HD Graphics' and select 'Uninstall').
4. Restart the computer
5. Check the Display adapters in the device manager again, there should no longer be Intel HD Graphics, but something Generic... If you still see Intel there, repeat steps 2-4
6. Install the drivers you downloaded in step 1
7. Restart the computer once again
8. Congratulations, you have the latest Intel driver
9. Optionally repeat step 2 and set the desired option of automatic driver installation.
If anything goes wrong, you should always be able to move back to the original driver, as it should remain in the system (didn't try, cannot confirm).
I will be more than happy if you provide any feedback to this, whether the performance increased for you, etc.
