Tekken®5 Dark Resurrection [NPEA00019]

edit:  newer updates of RPCS3 have changed the location of the "Maximum Number of SPURS Threads " option that you have to change from "Unlimited" to "3" in order to restore perfect performance. It is now located under the "Advanced" tab, so you no longer have to do the .ini edit to reveal the option in the usually hidden "Debug" tab.

Solution works perfectly.
Game is back to running at a locked 60fps.

Thank you.
