JPCSP Official Requirements?

[gid15]

Which results do you get when running the demos/compilerPerf.pbp?
This is a pure CPU test (no graphics), comparing the performance of Jpcsp with a PSP.
Such a test would be required for graphics, as this is the main bottleneck for most games.
I've tried to describe in the README.txt why the graphics implementation is often slower than on a PSP:

Code:

OpenGL provides some optimization techniques for application developers when they
follow some basic principles (e.g. grouping the display of similar graphics together,
reusing the same data at each frame...). The PSP does not use the same optimization
techniques, e.g. there is no real advantage in grouping similar graphics together,
or reusing the same data at each frame. So, the PSP programmers are optimizing for
the PSP, which is not the same as optimizing for OpenGL.
The Video configuration options allow the activation/deactivation of OpenGL techniques:
they might improve some games if their programmers by chance more or less followed
the OpenGL principles, but they also might decrease the performance if the game
programmers did something completely different (which is also legitimate on a PSP).
