I've got random fps drops in all my games since this summer.
So I thought that i should upgrade my videocard driver. But there is a problem with my radeon video card driver. I tried to install the latest driver and it gave me error 174. So i cheked the supported hardwares in the latest driver, and it said that it support mobile series (notebook) AMD Radeon HD 8500.
I've got a Lenovo G505s Notebook (bought it two and a half year ago) with
AMD A8-4500M CPU
Dual Graphics: AMD Radeon HD 7640G an AMD Radeon HD 8570M
8 GB RAM.
And my operation system is windows 10 x64
Can some help me to fix this problem?
