legacy openGL much better in OS X than new core option

[cekuhnen]

screen refresh rate is faster

rotating the view with core option lags roughly every 90 degree or so

I though that mode should be faster but legacy seems to be better

os x 10.10.4

Hi,

We will look into this graphics card GTX 970. This is the exact reason why we didn't make OpenGL core profile as the default driver since it may not be well supported by some graphics cards. 

Thanks
