GPU Issue after updating drivers

Question

Usually games on my PC work perfectly. However after updating all the PC drivers (including Intel(R) HD graphics), games won't work properly, they are slow and graphics are low, I have an example.

Here are the details:

Answer 1

The latest Intel drivers have a registry key to simulate memory.

The graphics driver now reports some amount of fictitious “dedicated” graphics memory to the operating system (128MB by default) to work around applications issues in a number of games. These games incorrectly look for some amount of “dedicated” graphics memory because they weren’t coded with the unified memory architecture for processor graphics.

The amount reported can be modified or disabled if desired by changing the following registry value:

HKEY_LOCAL_MACHINE\Software\Intel\GMM, create a REG_DWORD value named “DedicatedSegmentSize”. The value is interpreted as number of MB to report (0-512MB). A value of 0 disables reporting the dummy memory segment. If the registry key/value is not found, the driver will report the default 128MB.

So, create the DWORD 32Bit DedicatedSegmentSize under HKEY_LOCAL_MACHINE\Software\Intel\GMM and set it o 512 (Decimal).

Now try to run the game.
