Sure, I'll do a binary search style on the builds and see where the speed drop happened. It will probably be tomorrow before I can start though.

As for settings:
I do not use any cheats (Enable cheats unchecked).

Changing the bezier quality to low might gain 1-2% speed increase. Kind of hard to tell exactly as loco roco jumps around in speed quite a bit. Changes the locorocos to look more like hexagons than round, though low is much higher quality in the new release than the old one

My normal setting has been unbuffered rendering and 4x display resolution, as I didn't notice any issues with it in the games I play. Switching to buffered rendering:

4x rendering and 1x display is roughly the same speed as unbuffered and 4x display, although they jump around in speed in slightly different ways.

There is roughly a 5% speed difference between buffered 4x rendering, 1x display and 1x rendering, 1x display. Changing display from 1x to 4x is a huge quality increase, but only seems to affect speed ~1%.

Unbuffered with 1x display is slightly faster than buffered with 1x rendering and 1x display. Also worth noting, there is a pretty decent difference in speed between unbuffered 2x display and unbuffered 1x display, but then not much difference between 2x display and 4x display.

My normal settings in regards to those speedhacks are:
Block transfers off (old and new version)
Disable slower effects (unchecked)

If I check disable slower effects, it provides roughly 2% more speed in MHP3 village bottom.

Thanks for the replies
