Is there a way to match the Model 3's refresh rate?

So while I downloaded the latest SVN version I was wondering that if there's an option on a PPC frequency to match the actual 57.7 FPS Model 3 framerate? So the game's presentation looks closely to the real thing so I realized the emulation is improved and I want to make it accurate as possible. The first option I tried I overclocked the PPC frequency to 166 MHz(Which is the Model 3 step 2.1's CPU clock speed) It did the trick a little bit but some parts of the game drop down sometimes 56-55 FPS sometimes at 60 so it's not locked for some reason
