GL4ES (OpenGL 'emulator')
 

Has anyone tried GL4ES to port OpenGL games on Sailfish?
It's a very nice library, you can find it here: https://github.com/ptitSeb/gl4es

I used it to port Eternal Lands on Android, and the performance is really nice.

There are plenty of OpenGL games for Linux, and with Gl4ES most of them should work on any Linux platform that supports OpenGL ES.
