I've been testing the new HD soft plugin on my Nexus 10 (2560x1600p) and comparing it with the other options in Spyro game.
Here is a screenshot using Software renderer:
Another one, this time using OpenGL renderer:
And the last one, using HD software renderer (in 4X resolution and FXAA scaling enabled)
So the conclusions are:
-HD software has better colors than the OpenGL plugin, just like the normal software mode
-OpenGL has the sharpest image, HD software doesn't look as sharp as OpenGL, probably due to the fact that OpenGL runs in native screen resolution and HD software runs in 4X PSX resolution (even with FXAA on)
So my request is: could you add a higher resolution option for HD software mode? for instance 8X resolution? or even better, a "native resolution" option where it uses the native screen resolution?
