Also, has anybody here played GT5? Nothing on the 360 looks that good. And I'm a Forza fanboy myself.
That's false for the most part, and I have extensively played both series for a long time.
3/4ths of GT5's content (tracks and cars) are imported from the last generation and look terrible. Next there are consistent screen tearing problems and frame rate drops.
GT5 has a multitude of graphic problems ranging from poor anti-aliasing on shadows to lighting bugs on some tracks.
Where GT5 does look good is in the replays and photo mode, and this is solely because they have a much better lighting engine (which they licensed from Illuminate Labs) which makes the cars look a lot more realistic.

Honest question: How exactly does a racing game indicate graphical prowess? Yes it looks great but modeling car doesn't seem that difficult. It's a lot of smooth edges and they throw a bunch of shiny on top. I would be a lot more impressed with with someone who could make a great looking person/animal or even a rock with some actual texture work and a **** load of polygons.
Car modelling is exceptionally difficult. Each car is scanned in an intensive process. Each car has a very high polygon count. For example, in order to show tire flex (deformation) the tires must consist of dozens of polygons. Some cars have working aeros which make it even more complex, or perhaps they have visible engine bays. Then you have to interior and driver. Anywhere from 500,000 to 1,000,000 polygons. Forza's Autovista cars are extremely high polygon count, several million or so.
Next up, the best racing simulations run at 60 FPS. Forza has a very solid frame rate, and they do this so their physics have a consistent fidelity with the onscreen action. Racing games that run at 30 FPS will suffer from input lag and other problems.
Finally, a car in a racing game can be moving up to 270 MPH, the game engine needs to account for that. I've never seen an FPS game allow you to travel that fast, and if they did, the amount of pop-in would be huge...Forza features no pop-in and a considerable draw distance.
That said, Forza is running cheats similar to what most FPS games do, not modelling certain things during action and so on.
Turn on Photomode during a race in Forza, and you'll see what I'm talking about as a bunch of hi-res textures and models come in.
