Last Story bar conversations slow down

[drhycodan]

On OpenGL, when you're at the bar in the last story, conversations tend to slow down quite a lot on certain lines, namely the line "get some alchohol in ya".  Is The last story using Bounding Box erroneously?  This also happens in Paper Mario during the boat transition scene, turns the game into a slideshow.  I have a GTX 980, so why am I still getting slow down in those scenes?  In D3D, I get no slowdown at all during those scenes, so is there something wrong with my OpenGL driver or is that just how slow OpenGL emulates BBox?

In the Last Story case it is efb to ram that causes the slowdown. D3D handles efb to ram faster than opengl.
