Why dolphin use opengl 3.3 instead of 4.4?

[Mr papier]

Hello,

I'm using Debian 8 with the fglrx driver version 14.201 and when I compile the last version of dolphin, dolphin say that Opengl 3.3 backend is loaded while I can Opengl 4.4. Moreover when I put the game in full screen, I have a gorgeous white strip on left side of my screen.
Is there anyone who know how to solve this problem please?

That's only the minimum version Dolphin uses, IIRC it will still use OpenGL 4.4 features if available.

At least on Windows, it should do the same on Linux though.

[Mr papier]

So, opengl 4.4 isn't available on dolphin for linux?

[Anti-Ultimate]

That's not what I said.

It uses OpenGl 3.3 but will use features from OpenGL 4.4 if available. At least that's what I think.

Could it be a limitation of the GPU or the drivers?

[Mr papier]

Ok but it's weird that it display the version 3.3. On dolphin's website it's recommanded to have opengl 4.4 supported on your conputer and some peoples on youtube using Ubuntu for example have Opengl 4.4 in their logs.

Please post the output of "glxinfo".

I think the limitation come from the driver otherwhise I couldn't install the fglrx driver

[Mr papier]

here is the output of glxinfo | grep OpenGL

That seems about right. I wouldn't worry about it saying 3.3, it will most likely still use 4.4 features.
