Скачать или смотреть WebGL2 - Performance Linux vs. Windows with transform-feedback

OpenGL/C++ under Linux (GPU: intel HD 520):
1 million particles @ 60 fps

WebGL2/JavaScript under Linux (GPU: intel HD 520):
1 million particles @ 60 fps

OpenGL/C++ under Windows 7 (GPU: nvidia GTX 1070):
1 million particles @ 60 fps

WebGL2/JavaScript under Windows 7 (GPU: nvidia GTX 1070):
0.25 million particles @ 60 fps
1 million particles @ 23 fps - WTF?!

Here are the links to the C++- (either bzr or git) and WebGL2-implementations as mentioned in the video...
