" In the current issue of the Japanese magazine CG world a few details on
the Biohazard 4 porting on the PS2 are revealed.
They say that in the Gamecube version Capacom used 24bit textures.
On the PS2 they have to use 4-8 bit textures.
The Leon model in the GC version is made of 10.000 polygons.In the PS2
version that number is halved.So 5000 polygons (for a comparison the same
magazine affirms Solid Snake in MGS3 is made of 4000 polygons).
Thanks to the higher bandwidth of PS2 they can use more textures than in the
Cube version but they have to balance quantity with quality to avoid
problems with frame rate."

" I think it's going to look noticeably uglier. The problem for me is that
it's basically one of my very favorite games this gen, and if they add a
bunch of content, I'm going to have to buy the damn thing again to play it
and see all the differences"

" According to a japanese publication (CG World), the Capcom team working on
the PS2 version of RE4 are facing a very difficult time porting the game to
Sony's console.

Here are some few points they mentioned in the article:

------------------------------------

1). The original team headed by Shinji Mikami was able to incorporate 24-bit
textures into the GameCube edition of RE4.

However the team working on the port of RE4 will have to incorporate
downsampled 4- and 8-bit textures into the PS2 version, whose texture memory
capacity is far smaller than that of the Nintendo console.

------------------------------------

2). The polygon count used for the main protagonist (Leon) will have to drop
down from 10.000 seen in the GC version, to half that amount in order to
perform well on the PS2 version.

The magazine mentions that Leon has almost 3 times the amount of polygons
than the Solid Snake character featured in Metal Gear Solid 3 for the PS2.
Snake is made up of only 4000 polygons.

(As a side note, according to Factor 5, the pilots from Rogue Squadron were
comprised of 4000 polygons. The X-Wings themselves, were made up of 30,000
polygons!)

------------------------------------

3). Due to the PS2's huge Direct Memory Access bandwidth, the team working
on the RE4 version will be able to provide an exceptionally high number of
textures into the game.

However, adding such textures to the polygons will slow down the frame rate
of the game, even more so than it occasionally happens in the GC version.
This due to the PS2's limited texture memory capacity.

The PS2 version will have dramatic frame-rate problems if they try to
include all the texture layers and polygonal lighting featured in the GC
version. Some major adjustments will have to be made.

------------------------------------

4). The GC graphics engine can produce 50 percent more polygons to all the
characters than the PS2. The PS2's graphics engine can draw 10 million
triangles per second, but after adding gameplay, collision, logic, sound,
and so forth, the PS2 edition of RE4 ultimately will move around 30,000 to
50,000 triangles per frame, at an average rate of 30 frames per second.

The GameCube also has a faster CPU that can boost the frame rate to 60
frames per second (twice that of the PS2), and utilizes its texture
compression ability to deliver high-resolution textures with improved color
variance. "
