Did they work before the 8.1 update?  Do they support hybrid video (check with the manufacturer of the games)?

She was working before updating windows 8.1

Some of the games that are having trouble (far cry 3) and (the Amazing Spider-Man )

I found the solution :emotion-1::emotion-1::emotion-1:

You must download the latest version of amd from here http://downloads.dell.com/FOLDER01712273M/6/Video_AMD_W8.14_X01_A00_Setup-6GGGM_ZPE.exe

good luck

Hello I have I have a problem after adjusting the video card

Games became too slow

Is there solution :emotion-6:

Hi, 1.First off all install Intel HD 4400 driver and then install AMD 8850M Drivers. plz download drivers from dell drivers and utilities.Restart the system after each driver update.Then configure switchable Graphics to High performance.Then run the game. 2.If this wont help, run the game after compatibility test by right clicking the exe file. This method helped me in running older games like Mass effect 3..... Far cry 3 is having dark shadowy problem. I think it may be a driver problem.Updating to the latest driver from AMD site cant be done as the system will hang when it awakes from sleep mode.So use only dell drivers.... Hope this helps
