back to limit vps instead of fps as this fix fps limit and now it works correctly as now the sync between the plug in and the core is almost correct.

fixed fps display in the top bar, now it shows the real fps of the game.
some code clean up and some corrections to make everything work right in the reference renderer.
multiples xfb now is broken even in single core as is was not an error caused by dual core, i really dono where the error is,everything looks correct but if you test a game with multiples xfb or the ipl you will see the error.
ector if you can take a look at he code and throw me some ideas i'll thank you.
please test.
