Inspiron 15R 5537 AMD Radeon HD 8850M bad game performance in Windows 8.1 64 bit

Hi,

Here is my current installed drivers list.

Before I upgrade to Windows 8.1, everything is working fine with windows 8 drivers.

I have tried to use driver from amd.com, gaming performance is good but always pop up AMD graphic card driver problem and repaired issue.

Please advise solution for this problem as it has affected my confidence of your products.

Thank you.
