i still think Forza Motorsports for Xbox is gonna kick its ass

FALCON PUNCH!!!
Remember, it's not the speed that makes the difference, it's the architecture. The Emotion Engine is a 128 bit RISC processor. It doesn't need to be ub3r fast versus the Intel CISC architecture.
The primary goal of CISC architecture is to complete a task in as few lines of assembly as possible. This is achieved by building processor hardware that is capable of understanding and executing a series of operations. For this particular task, a CISC processor would come prepared with a specific instruction (we'll call it "MULT"). When executed, this instruction loads the two values into separate registers, multiplies the operands in the execution unit, and then stores the product in the appropriate register. Thus, the entire task of multiplying two numbers can be completed with one instruction:
MULT 2:3, 5:2
MULT is what is known as a "complex instruction." It operates directly on the computer's memory banks and does not require the programmer to explicitly call any loading or storing functions. It closely resembles a command in a higher level language. For instance, if we let "a" represent the value of 2:3 and "b" represent the value of 5:2, then this command is identical to the C statement "a = a * b."
One of the primary advantages of this system is that the compiler has to do very little work to translate a high-level language statement into assembly. Because the length of the code is relatively short, very little RAM is required to store instructions. The emphasis is put on building complex instructions directly into the hardware.
RISC processors only use simple instructions that can be executed within one clock cycle. Thus, the "MULT" command described above could be divided into three separate commands: "LOAD," which moves data from the memory bank to a register, "PROD," which finds the product of two operands located within the registers, and "STORE," which moves data from a register to the memory banks. In order to perform the exact series of steps described in the CISC approach, a programmer would need to code four lines of assembly:
LOAD A, 2:3
LOAD B, 5:2
PROD A, B
STORE 2:3, A
At first, this may seem like a much less efficient way of completing the operation. Because there are more lines of code, more RAM is needed to store the assembly level instructions. The compiler must also perform more work to convert a high-level language statement into code of this form.
However, the RISC strategy also brings some very important advantages. Because each instruction requires only one clock cycle to execute, the entire program will execute in approximately the same amount of time as the multi-cycle "MULT" command. These RISC "reduced instructions" require less transistors of hardware space than the complex instructions, leaving more room for general purpose registers. Because all of the instructions execute in a uniform amount of time (i.e. one clock), pipelining is possible.
Separating the "LOAD" and "STORE" instructions actually reduces the amount of work that the computer must perform. After a CISC-style "MULT" command is executed, the processor automatically erases the registers. If one of the operands needs to be used for another computation, the processor must re-load the data from the memory bank into a register. In RISC, the operand will remain in the register until another value is loaded in its place.
I actually do understand all that too...
Also remember that the PS2 is only rendering out to 640x480 pixels. You can do all sorts of neato tricks to make stuff look amazing at lower resolutions without using too much computing power.
on this pic you can see how they're just splicing together pictures around a low polygon mountain shape: http://image.com.com/gamespot/images/2004/...1_screen003.jpg
pretty easy to make it look good when you're driving 100mph.

anyone see the toyota prius???
or the old school pulsar with the square rear hatch?
interesting...

Yea... I just want to see if the Gen2 GSR makes it... that'd be the shit if it did...
Oh yeah- easy as pie. Just throw up a bunch of random textures and the irregularities of a normal mountain show up on their own. You're not going to get many people pausing the game just to look at the background rendering.
