bb_145 - thank you so much. You did it! Genius!
You're welcome- glad I could help someone after all the help other users have provided me.
Though the thanks should go to crazyt... I wouldn't have known where to start without his link.
Sadly, I installed Minecraft and wasn't able to get anywhere near the performance (it was unplayable on lowest settings) I was getting when I had Windows 7 on the tablet. I think the EP-121 with Windows 8 still needs an official driver.
I'm hoping an official driver is released for the October 26th market release of Windows.
With new drivers not running Angry Birds =) (all of them, except Bad Piggies)
Said that OpenGL 2.0 not supported.
With stock Intel drivers works fine, but YouTube videos on IE10 not showing, and screen changing gamma by itself.
Also when I got back to stock drivers and ATK spontaneous touch clicks on lower corner returned.
tried the method mentioned for the Intel driver on Windows 8, I have an issue where If I turn off testmode my driver will stop working because it is not signed.
I see some have got this method to work, is there a certain way people are doing this or can this not be don't on Windows 8 Pro RTM?
All of you using RTM Windows or possible even a retail version: if you run Windows Update now you will get a signed version of the driver from Microsoft:
Driver Provider: Intel Corporation
Driver Date : 12/10/09
Driver Version : 188.8.131.5258
Digital Signer : Microsoft Windows Hardware Compatibility Publisher
I tested a program that requires openGL 2.1 and that works, so this is better then the previous situation; maybe they'll make improvements to it as well.
Thanks Goat! That's great news. I checked Windows update several times this morning, and it wasn't there, but it is there now. Works like a charm!
I put in the latest 704 BIOS then installed WIN 8 retail version and did all the Window updates - and did no other special driver installs.
That gave me the Intel Display Driver Version: 2.1.0 - Build 184.108.40.20658 dated 09-Oct-12.
The Windows Experience Index (WEI) detail report says I am still using DirectX 10, but the DirectX Diagnostic Tool (dxdiag) says it is version 11. (See How to determine the version of DirectX by using the DirectX Diagnostic Tool for info on dxdiag)
The OpenGL Extensions Viewer gives much more detailed info.
It shows that:
OpenGL 2.1 is 100% supported .
OpenGL 3.0 has 82% of its features implemented.
OpenGL 3.1 has 75%
OpenGL 3.2 has 50%
OpenGL 3.3 had 10%
and OpenGL 4.0 thru 4.3 has 0%
What Windows 8 experience scores are you seeing in this case? My gaming and business graphics scores are still much lower than I have seen a few others indicate.
2.3 (business) and 3.1 (gaming).
Is the method to roll back to a WIn 7 Intel HD driver still providing better performance ?
