While googling about Direct3D vs OpenGL, I found the following post by the user KHg8m3r:
There's a problem with the current drivers and Intel HD 4600. If you use any AA with an IR past 2x, you will hit massive slowdowns.
(I can usually run games around 2.5-3xIR with varying AF, fullspeed on my HD 4600)
That's the same iGPU as mine. I get lag while trying to run Sunshine and Twilight on 2.5/3 (even after updating the drivers). So I guess the driver problem he mentioned still exists or he just has a better CPU?
