Digital Foundry (Eurogamer) - GT5P vs Forza 3 Tech analysis.

[Reasonable]

Ok. I dont see it at all. But each to there own. FM3 is easily the better technical game. It has much more trackside detail and much better textures. GT5P has better lighitng ( which lends itself to look real ) but once you take your eyes off the cars, it's abundantly apparant it's missing alot. After playing Suzuka on both FM3 definately has the tech win fairly easily. It's apparant coming down the home straight for one. The horizon in FM3 is modelled with city etc ( as it is in real life ) whereas GT5P has nothing. The ferris wheel in FM3 is animated and working. It isn't in GT5P. Coming out of the s bends and up the hill. To the left through the wall theres nothing modelled in GT5P, just a white background. In FM3 theres caravans trees and a horizon. trees are 2d in GT5P. FM3's are fully modelled. The list can go on.

Again, it's a rendering engine review - that means resolution, frame rate, AA, lighting, particle effects, transparency handling, etc.  GT5:P is slightly suprior in all the main areas for rendering with the exception of motion blur and (perhaps) textures although personally I feel these are a draw in terms of detail overall.  GT5:P also renders more cars.

Forza 3 might have better physics, better backgrounds, etc. but those don't offset the pure rendering evaluation which is going to favour GT5:P because having 4xAA vs 2xAA for the same fps and resolution is simply superior, and having 2xAA at a higher resolution is a big difference in rendering evaluations, the resolution/AA factor alone would put GT5:P ahead in any rendering evaluation as it can clearly render essentially the same cars, track, etc. at a much higher resolution than Forza 3.

Look at it this way, Killzone 2 has the best rendering engine of any FPS I've played on PS3 or 360, but I don't think it's the best FPS, or has the best level design necessarily, or nicest textures, etc. compared to other FPS, but I don't let this cloud my view of its rendering engine capabilities.

Just because Forza 3 may have some better detail in surrounding world views, such as a city on the horizon, doesn't make much difference vs the huge resolution/AA difference, nor does a wheel detail, etc. - not when you're talking rendering capability.
