i think its time to report some new bugs as i noticed that its a pcsx2 bug:
this bug happens on all pcsx2 builds i tested since the 0.9.4 release build.
well, like i said, pictures saying more than words:
FF12 polygon spikes
and here the savegame, i renamed it to SLES 54354 serial (uk version) and hope it works:
