For some reason I'm having weird framerate between backends.
On Super Mario Sunshine NTSC-U (unlimited framerate

D3d11
native ≈ 45 fps
2.5x ≈ 18 fps

OpenGL
native ≈ 32 fps
2.5x ≈ 25 fps

Anyone know why this happens?

A couple reasons.

Lets start with your driver and OS.

You're running Intel drivers in Windows. This isn't great on OpenGL. Not the worst you could do for Intel drivers (OS X), but they're not as good as Intel's Linux drivers. Their Direct3D stuff is okay.

Next, 2.5 IR is simply more intensive, and the different backends scale differently depending on hardware and drivers. Unfortunately you're on Ivybridge so you can't use D3D12.

Honestly those framerates don't seem weird to me.

He may be referring to them proportionally. Like running the game at 2.5x drops the framerate by more than half with D3D11 where as it only drops it a few frames when using OpenGL.
