The JPCSP Team has recently put online revision 1984 of their ever-improving Java-based PlayStation Portable emulator for Windows PC, JPCSP. New features of the latest update includes some minor graphics improvements, performance enhancements and some other tweaks.

Changelogs:

• JPCSP v0.6 r1984:
  • Another small graphics fix: better detect GE parameter changes.
• JPCSP v0.6 r1981:
  • Fixed problem introduced by r1980 (was sometimes causing incorrect video decoding as reported by Darth1701).
• JPCSP v0.6 r1980:
  • Several performance improvements in the VideoEngine:
    • improved vertex cache: changes should now be always detected (no longer using a hash code)
    • provided an asynchronous vertex cache when sceGuDrawArray can be detected at compile time: the cache is then checked in a separate thread so that the cache is already up-to-date at rendering time
    • added a new option "Enable VAO" (OpenGL Vertex Array Object): this option can improve the performance in some applications, but not always. It can also reduce the performance in some cases. This is why this is only available as an option. This option is only active when enabling the vertex cache and the shaders.
    • automatic merging of sequential "prim" commands to optimize OpenGL calls
    • fast skip of GE commands having no effect (e.g. setting multiple times the same flag to the same value)
    • statistics are now disabled by default (probably only useful for devs). They have to be enabled by DurationStatistics.collectStatistics.
