Well I think there is a disconnect between what we are talking about. Crysis 2 isn't coded to the metal, in fact I don't think any game on 360 is. Its built on high-level API's just like pc, although the 360's will be alot more specific and optimized.
AFAIK Sony is the only company that allows "to the metal" coding(IE, Assembly or Machine language that is barely readable by humans)
Heres an example:
A standard hello world in C looks rather simple
Code:
#include <stdio.h>
int main(void)
{
printf("Hello, world.\n");
return 0;
}
The same program in assembly is like this
Code:
.syntax unified
@ --------------------------------
.global main
main:
@ Stack the return address (lr) in addition to a dummy register (ip) to
@ keep the stack 8-byte aligned.
push {ip, lr}
@ Load the argument and perform the call. This is like 'printf("...")' in C.
ldr r0, =message
bl printf
@ Exit from 'main'. This is like 'return 0' in C.
mov r0, #0 @ Return 0.
@ Pop the dummy ip to reverse our alignment fix, and pop the original lr
@ value directly into pc the Program Counter to return.
pop {ip, pc}
@ --------------------------------
@ Data for the printf calls. The GNU assembler's ".asciz" directive
@ automatically adds a NULL character termination.
message:
.asciz "Hello, world.\n"
And thats simply to display "Hello, World". I can't imagine actual 3d in this shit. AFAIK SONY WWS is the only group that uses a significant amount of this code, due to their specialized ICE team.
So yeah you have basically Vanilla DX3D/OGL which the the vast majority of games are wrote on, you have subsets/supersets which consoles rely on, then you have the truly hardcore shit.
