HD4000 and Windows 8.1

[MWill31]

I recently upgraded my Lenovo Ideapad to Win8.1 64bit from the factory default 8.0 64bit. I suspect as part of the upgrade the graphics driver has been updated as the graphics properties app has completely changed. Device Manager tells me I'm on version 10.18.10.3316 which aligns with the latest 8.1 64bit driver from the download centre.

The laptop is primarily for work but in my down time I have enjoyed playing Dungeon Siege which I installed via Steam. Since the upgrade the game runs in a small window in the centre of the screen (not in a window, the rest of the screen is black around the window). As it's quite an old game the max res it runs in is 1024x768. Before the 8.1 upgrade the game would fill most of the screen. Also the graphics in the game keep breaking up as I scroll around.

Normally in these cases I would install the latest graphics drivers and this fixes these types of glitches but as I'm already on the latest version not sure if I should consider rolling back to a previous version.

Any advise would be great.

Check changing the aspect ratio options in the graphics driver as shown here:

One thing you may need to test is setting the option to full screen.

Additionally try the manual installation method for the generic driver posted here:

For the manual installation instructions, check this article:

http://www.intel.com/support/graphics/sb/CS-033916.htm Desktop graphics drivers | How to manually install a driver in Microsoft Windows 8* or Windows 8.1*

Do this even though the version seems as the one that you are already using, as the driver itself is different since the one you are using now is a driver provided directly by Microsoft.
