But can anyone show me a PS2 game which actually looks better than RE 4, at least to PS2 RE 4?
I don't think RE4 PS2 is a good example of good port and here's why..
1st : The release date, the game was originaly developped for GameCube, the PS2 was never considered until end of 2004 when they announced the port of the game because Capcom know it was flopping on GameCube (and because cost many money).
2nd : The PS2 port was never dev by Capcom Studio 4, but by Inafune team (wich they developped Seperate Ways too)
3rd : One of main curious thing is RE4 PS2 port running 480i 24 bits color instead of 16bits colors with gradient. Prooving that the PS2 have enough bandwitch for running better fx / texture / lightning at 480i. (PS: 480p running indeed on 16 bits color with gradient, but this isn't a big deal bc even the 480i version was enough clean).
4th : The PS2 version have better resolution than the GameCube version. GameCube version running at "640x360" resolution style (or maybe lower, so with black bars cutting resolution), no widescreen support.
Instead, the PS2 version running at 512x448 stretched and widescreen support (then flattened for 4/3 screen). Once again, the PS2 have more pixel on the screen than the GC version for some reason.
5th : Texture was never converted in a good way. Maybe bc memory issue and needed released the game in a short time. The devs needed more time for optimise the engine for the PS2 architechture. But this is basic texture conversion than you can cleary see in bad port at 2000.
6th : Another curious thing is the cut-scene. We all know cut-scene was in real-time on GameCube and not on PS2. Why ? Because more faster way and no difference ? Yes, this is one of reason. The PS2 was a MPEG2 Decoder can be used in a game, and this is one of reason why FMV looks better on PS2 than a GameCube / Xbox in so many games.
But for Resident Evil 4, even if the FMV looks pretty ok on CRT (and way better than the trash PC 2007 version), if you remove the FMV from the PS2 Data disc, curiously, the game still running the cut-scene. Of course with no characters models and no sound. But area and camera works is still there with PS2 assets. So this prooving cut-scene are still hardcoded on the PS2 version. The FMV technique is just a way to render faster for the release time and no needed optimisation models / texture works.
So no, RE4 is not a perfect port and if you know a bit the PS2 hardware, you wondering why devs not push PS2 to limit...
For me, this is purely timing question.
I'm still pretty sure PS2 can do much more on RE4 instead what we've got (not a perfect 1:1, bc you can't with the hardware difference, even a game like Crash Wrath of Cortex run like shit on GameCube, but a least a more impressive port)
Still RE4 PS2 port is impressive, but is not as polished like other Capcom title in the same support (or other AAA PS2 title)
This, is Haunting Ground on PS2 a Capcom title
This one is God Hand, still Capcom
Devil May Cry 3, still Capcom + 60fps (so if you cut framerate, you can push more)
Resident Evil Outbreak is not bad at all too for a "low budget" Resident Evil and all background is full 3D (Wich is clearly better than Code Veronica)
Even Resident Evil Dead Aim is a curious thing (Gun Survivor 4), have some interesting visual and it's running at 60fps.
This prove PS2 can handle way more better thing than people suppose
