We put both Gran Turismo 5 and Forza 3 under our Lens to see which racer performs the best.


Finally, after five years of waiting the highly anticipated Gran Turismo 5 has hit store shelves, but was the wait worth the while? Today we’ll help shine some light on that question by doing a performance analysis on the hottest racing titles on the market.  This time we simply focus on the performance differences between Gran Turismo 5 (for the PlayStation 3) and Froza 3 (for the Xbox 360). These two games have been considered the industries best racing exclusives on their respected platforms, but we’re determined to expose which console out performs its competitor.  Jump into the driver seat of your choice, and come join us as we uncover the performance differences between these two racing gods.

Graphics: In general, vehicle models across platforms looked incredible and photo realistic. However, the major differences between the two versions was how each platform handled vehicle damage. It’s was clear that Gran Turismo 5 had implemented a rarely used feature called Decal Tessellation. Without going into too much detail, the idea behind this technique is to take a displacement map texture, project it onto geometry - just like a decal – and tessellate the geometry in real time so that the displaced geometry looks like physical damage to the vehicle. Plain and simple, mimicking realistic damage on the fly. On the flip side, Forza 3 simply swapped out decals and models which made collision between vehicles look rather dull compared to Gran Turismo 5. Although we’re not comparing graphical differences in this article, a little information about the vehicles damage systems felt appropriate.

Performance: This category left us rather shocked because performance expectations for Gran Turismo 5 were quite high. Unfortunately, we were left very disappointed and confused. Our analyzer recorded that Forza 3 had a much more stable frame rate throughout. As seen in the video, it’s clear that Gran Turismo 5 was having difficulties maintaining it’s projected 60 FPS, while Forza 3 was locked at a perfect 60 FPS throughout . In addition to the fluctuating  frame rate, Gran Turismo 5  screen tore 20% more than Forza 3 did.

On a final note, on average both games performed pretty close to one another averaging around 60FPS while in-game. However, we noticed that your previous race  would replay back at perfect 30FPS. Listed below are the average frame rate and screen tearing percentages.

Loading: Although we didn’t capture any load-time samples between versions, we can confirm both had their fair share of loading. Again, this section wasn’t a focal point for this article but the load-time differences were probably a couple seconds different from one another.

Conclusion: There’s no doubt that Gran Turismo 5 and Forza 3 are beautiful looking racing games, but quite honestly we were expecting a little more from Gran Turismo 5 in the performance department. Not only did Gran Turismo 5 constantly fall below the 60 FPS mark, there was quite a bit of noticeable screen tearing occurring throughout. While Gran Turismo 5 may have a slight visual advantage over Forza 3, our analyzer proves that Forza 3 out performed Gran Turismo 5 in almost every video we captured. Lets hope Sony releases a performance patch in the near future, but Sony please don’t make us wait too long…
