From the Ready At Dawn website.

It seems like the recently released screenshots of God of War: Chains of Olympus have caused quite a stir on the various bulletin boards. First our banner shots got people wondering if a ‘wide screen’ PSP was in the works, then the highres screenshots got widely dismissed as ‘doctored’.

So, here’s the whole truth and nothing but the truth: NO those shots are not doctored in any way, shape or form. They are rendered on the PSP, using in-game geometry, in-game textures and in-game lighting. They actually all show real game locations that you will be able to play in the full game.

They are indeed rendered at super high resolution thanks to a feature of our engine allowing us to render up to 1080p using PSP hardware, on devkits only obviously. The reason the web site shots are wide is because these were made for our banners on the site. The reason those show practically no aliasing is because they are higher res than the PSP screen. Aliasing is there but is just using really small pixels, almost masking the problem. BTW, we also have 1080p movies of the gameplay, pretty cool stuff.

Rest assured that those locations do run at full frame rate when displayed at normal resolution on the PSP so we’re not cheating there either. What you might see is compression artifacts on the JPEG versions of the shots or sometime anti-aliasing if someone took the bigger shot and shrunked it using some art package (as these do anti-alias automatically sometime). But that’s not us cheating!

Why the highres shots you may ask? Because we can.

I'm really shocked at how much power the PSP actually has.

Then it IS cheating. Unless you render at a higher resolution on the PSP, then down-sample to the video buffer on the fly - the game will have a lot more jaggies, and will not look as smooth as this. MGS2 on the PS2 used this technique to great effect.

heh... "in game shots... we promise!" haven't heard THAT before...

They are upscaling the screens using the dev kit, also the PSP screen size and resolution of 480x272 will reduce the jaggies.  So yes, there will be some jaggies, but the graphics WILL be the same...ie. same textures and same complexity.

So they are not cheating. 

come on man he really doesn't want to admit that the PSP looks way better than the Wii let alone what the DS can do. Let the Nintendo guys have the "this isn't real" or "this is cheating" thing, after all we get Chains of Olympus. 

I wasn't aware people were saying these screens weren't real. The PSP is a watered down PS2, it should be able to produce screens that are almost as good, especially with a much smaller screen estate.

 lol, just lol.

 Please.

The PSP is a graphics mammoth...
