What is the first git build that is slower, and the last git build that is faster? There are 68 changes in that range, the more you narrow it down, the more likely it may improve.
Anyway, you can disable the graphical improvements by unchecking "simulate block transfers" in settings. If this makes it faster, that's unfortunate.
Also, I guarantee that compatibility is better with 0.9.8-anything than with 0.9.6-anything. Maybe not for the few games you tried, but definitely on the larger scale.
