HW Tessellation what does it do?
I cant find any info on what HW Tessallation does in PPSSPP, can someone tell me what it tessellates, because I cant see any difference when its turned on or off, I tested Monster Hunter P3rd and Kingdom Hearts.

RE: HW Tessellation what does it do?
Hardware tesselation is used for spline/bezier curves, activating it will simply move out processing of those pretty curves from CPU to GPU, depending on your hardware this might be a speedup or a slowdown nothing else should be expected from it. Also it does not have a quality setting like software implementation so more often people with weaker hardware might still get better results with software implementation, just set to lower setting.

Either way many games use spline/bezier curves in very limited form if at all, FF IV abuses it heavily in some spells like Thundaga, Patapon games use it for much lighter wind effects, and of course Loco Roco games are pretty much build around those effects.
