Hey guys,

I'm not sure if you guys can even help me out here:

Lets say you take a premium car of your choice from GT5 onto the Nurburgring map on GT5, Then do the exact same thing on Forza 3 (under the same conditions).

What game will deliver the best physics?

Can anyone explain how Game A delivers better physics than Game B, like on what parts..? Do we have any advanced-tech guys here?

HELP IS VERY APPRECIATED.

This is the best comparison I was ever able to find, but I believe there are a few more. In terms of physics, GT5 is more accurate.

Couple of reviews from sim orientated site I found (in addition to above link):

Both titles have pretty good physics but from a sim perspective (i.e. less hand holding and more accurate representation of car interaction with the road) GT5 seems to have the edge so far as I can tell from what I read plus my own play through.

It sometimes feels like Forza 3 could have matching physics but the balance leans towards gameplay vs true sim and it mostly feels like the game holds back from what it could simulate in the name of making races more fun. The road surface and interaction with it also seems superior in GT5. The surface feels awfully even in Forza 3 whereas in GT5 you can really feel the road undulate and the impact on the car's physics.

Again, both are good, but GT5, particularly as you advance, seems to provide the more accurate driving physics and road surface.

Neither - of course - matches the physics of the PC based driving sims. But GT5 comes a bit closer than Forza 3.

GT5 obviously has better physics then Forza 3

Using Nurburgring specifically, they both have their pro's and cons.

GT5 has the Nurburgring tracks accurate to 12 inches of elevations, don't know exactly what Forza is, but GT5 has the track more accurately modeled.

GT5 will have better car physics on the very first lap, on the premium cars (not the standard one), but not in every regard. From my experience with the game GT5 will model weight transfer during cornering more accurately then Forza, but Forza will model body roll more accurately. This is because in Forza Motorsport 3, engine locations are only placed in general areas (front, mid, rear), where GT5 places them exactly where they belong.

However Forza Motorsport 3 has more accurate real time tire deformation, so after just 1 lap Forza Motorsport 3 will begin to model cars better. Tire deformation on just 1 lap on Nurburgring in real life makes a huge difference, that's why all lap times for production cars are set on new tires, on the first lap. Playing Forza you notice this.

So to sum it up, GT5 Premium cars model weight transfer and cornering in general more accurately for about the first ten minutes of a race. Most races fall within this duration. However anything long, and Forza Motorsport 3 does it better.

However none of this matters, Forza Motorsport 4 will be much better then both games in every aspect.

THANKS! (You too reasonable!)

yet another comparison thread, as if we don't have enough of those already ¬_¬

If you're doing endurance races GT5 will simulate the tire wear. Best person to ask about this espect is lestatdark as he's the only one I know of who's done 24hr racing on GT5 (and probably the endurance races on Forza too).

OP: I think the tracks (surface, width etc.) are more accurately represented in GT5 than in Forza 3. Drive down Circuit de la Sarthe on one then the other I find the road surface more noticable on GT5 plus the width of the track is wider in Forza 3 than in GT5.

Yea, but Forza does it better. I haven't done a 24hr endurance race on GT5, but I have done a few 1 and 2 hour races, Did all the endurance races in Forza 2, and a handful in Forza 3.

Overall GT5 is better, but tire deformation is Turn 10's trump card in terms of what makes Forza 3 a good simulator.

lol people who don't know what their talking about XD

question: when was the last time you played GT5?
