Many laptops don't work properly with the "Vanilla AMD drivers" did you get yours from your laptop maker? If not, I would suggest sticking to the last driver they supplied and talking with them about any issues you have. If they are not updating their drivers as AMD introduces the new reference drivers then they certainly should be. Many of these makers don't support their laptops very well and is why IMHO laptops make poor choices for gaming machines.
You likely have tried many of the things I am going to link to, but if you have not seen this page it offers a lot of good advice for switchable graphics:
I did got my laptop from Asus market, I baught it from a mall.
I went to the link you gave me and I tried that already many times, unfortunately the sample in the link is about having 2 different Graphics but mine is different I have 2 AMD graphics which is R5 and HD 8500M.
I have another HP laptop that has no problem cause is has 2 diferent Graphics the 1st one is Intel HD and AMD M330.
I want to ask question. When I installed the driver from AMD does it recognize 2 AMD graphics graphics to be installed automatically?
I just want to give more pictures about this, and I hope there's a solution cause I'm really confuse what's going on. I search in youtube, forums and etc.
I hope this thing will help, as you can see both graphics card have same VRAM which is 512mb, the HD8500M just copied the Readeon R5.
When I ran the CPU-Z and MSI afterburner it just recognize the 512MB VRAM/Radeon R5 from APU.
As far as I know there should be another tab in the DX diag Shows HD8500M with 2000VRAM. But I got only one Display.
I'm begging for help. I'm challenged to solve the issue but I feel frustrated. I'm thinking if this is a DEAD hardware already.
I understand your frustration but the people to talk to on this would be Asus.
