Dolphin crashes on dedicated graphics

[klapek]

I've just bought Lenovo y580 and have problem with Dolphin. I've installed it a bit earlier and just run, to see how it works. It worked properly on GTX660m, I can't even run graphic options.. Today I wanted to play few games and when I'm using 660m, it crashes. There aren't any problems on HD4000. What's the problem?

Bad driver
Download and install latest beta driver for Nvidia GPU
Warning : Do not select Nvidia GPU via Directx11 backend - Dolphin , just leave Intel HD there . If you select it directly , Dolphin will crash
You should add Dolphin to "High performance Nvidia Processor" via Nvidia Control Panel and set "Battery/Power Plan" to "High Performance" , Dolphin will use Nvidia GPU even if it displays Intel HD

I have the latest Nvidia drivers, energy management is set to high performance.

I did it and it works, but it's strange, cuz i ran Dolphin on D3D9 yesterday without any problems, but isn't D3D11 slower?


//My firend has qm3630 and gtx640m and runs Dolphin on D3D9.

Most games run better/faster on Directx9 backend , some games run better/faster on Directx11 (Mario Sport Mix for example)
