why does java not use 100% CPU

See the README file in Jpcsp:

Code:

Jpcsp takes full advantage of dual-core processors, matching the PSP dual-core architecture. Even a quad-core can give a small performance improvement by leaving free CPU cores for the Java JIT Compiler and the graphics cache.

However, not all PSP games are using 100% of the PSP CPUs: depending on the game, you can reach 100% PSP speed even if your computer CPU is not used at 100%. If the game feels slow, try using different configuration settings. Usually, you can find the best settings in the game thread on this forum.
The graphics performance also depends on the performance of your graphics card, not just your computer CPU.

TNX but I am using the recommended settings from the thread already and its still dipping frames maybe Ill wait for a newer version of the emu w0hen its available TNX and also I noticed that when you press the start button and go ingame again the texture filters seem to go off and give me nice PSX looking game which can be fixed by going to another room but other than that its a great project keep it up
