Lenovo G50-45 performance in games problem

[Neba021]

I bought brand new laptop , a mounth ago... Its Lenovo g50-45 :
-CPU : AMD A6-6310 APU with AMD Radeon R4 Graphics
-Ram : 4GB (3.56) useable
Motherboard: LENOVO Lancer 5B2
Graphics : AMD Radeon R4 Graphics (2034MB)
1TB hard
so I have a problem, that is: I tried to play League of Legends and my fps was in begining of game 60 for a 2 minutes of playing and then going down for a 35 FPS ,and I changed quality from High (shadows OFF)to medium, and then 35-47fps again,then I set everything on vary low , same.. 35-50fps. I search system requirements and it told me that my laptop should run this game on 60fps easy. So I tried to install other games and every game I play I have 35-45 fps... ( CS:Go, Grid... many of them) i dont know how is possible that I have same fps on high quality and low...power plan is high performance.

Hi,

First try to uninstall/reinstall the graphics card driver.
- Uninstall the graphics card driver from Device Manager and in Programs and Features as well since it should have something related to AMD in there as well.
- Once uninstalled download and install the latest driver from AMD support site.
- Here's the link: http://support.amd.com/en-us/download
- Use the Auto Detect feature so they could give you the latest and accurate driver for your graphics card.
- Lastly reboot it once the latest driver has been installed.

If doesn't solve the problem overheating might be the cause and opening the laptop the cleaning and reapplying a new thermal paste might be necessary.

Make sure you are running on wall power not battery when doing your tests. Running on battery the power saving will kick in on default settings and will lower speed.

what do you mean when you say wall power?

Wall power = power plug plugged in, not just on battery.
