Dolphin Under Linux Limited to 30fps

I'm running Dolphin 5.0 in Linux Mint 18. I'm trying to figure out why the frame rate is limited to 30fps. My CPU usage shows only about 15% max usage across all 4 cores. The frame rate indicator shows a solid 30fps and the game runs at half speed. This happens in various games, often menus and opening logo screens are fine running at full 60fps. Is this an OpenGL issue maybe? Intel Core i5 4575, GeForce GTX 240. These games run fine in Windows 7.

What games are you playing? Many games only run at 30FPS.

vsync is turned on somewhere in the line. Check Dolphin's graphics settings, and your GPU's settings and turn vsync off.

Turned off VSYNC and this improved performance, but I'm still not running simple GameCube games at 60fps. After some research I've determined this is due to poorly optimized nVidia OpenGL drivers. Thanks nVidia, you gave me the only reason to dual boot Windows.

Nvidia has the best OpenGL drivers of the three big vendors. OS doesn't matter when it comes to nvidia drivers as most of the code is shared

Are you using proprietary drivers as you should?

try the environment variable:
__GL_THREADED_OPTIMIZATIONS=1

It's enabled by default on windows. Also have fun to configure the power management of your GPU to performance when dolphin is running. Everything else is the same as on windows - performance-wise.
