Virtua Fighter 5: Final Showdown [NPUB30625]

Hey, don't know if this thread is alive or not but I have a question. My PC, with a GTX660Ti, and an FX-6100 OC-ed to 3.8 ghz, is running the game slowly at 18-20 FPS. I saw a video on Youtube that played the game at 30 FPS, which isn't great either but it's more enjoyable but with a stock FX-6300. Is there so much of a difference that I won't be able to play the game at 30 or 28 fps? Thank You for the answers.
