Lenovo G500 win 8.1 Radeon problem

Question

Hi i bought Lenovo g500like a year ago and recently updated my system to win 8.1and then eveything starts. My games FPS drops for 30-40 to 11-12 (games like witcher 2 which should work fine on Radeon HD8750M). So i decided to install new version of AMD CCC but installation always end with problems and gaming still does not improve. Also if i try to turn off inter graphic card in manager it says that AMD drivers are not installed either they do not work properly and to reinstall them. What can i do? Please help!
Here is CCC installation error log.

hi skladzien,
Welcome to the Forums.
For systems that have two GPU (Intel + AMD), you will need to update both the GPU drivers for Win8.1 for the graphics switching to work (chances are, the system is not switching properly to the Radeon HD8750M when playing games and it's only using the Intel Graphics):
Things to try:
1. Navigate to the Control Panel (icon views) > Programs and Features and uninstall anything that relates to Intel Graphics and AMD / ATI Graphics drivers (reboot if necessary).
2. Install these drivers in order and reboot if necessary:
1st: - Intel Video Driver for Windows 8.1 (32-bit, 64-bit)
2nd:- AMD Video Driver for Windows 8.1 (32-bit, 64-bit)
3. Set the power settings of the unit to High Performance and configure the AMD Control Center to max performance.

When finished, try running a game and observe the FPS.
