Many PS2 games render at 320x480 or 640x224 internally and only output at 640x480 (which explains the jaggies in DOA2 btw). So what people mistook for a lack of anti-aliasing in comparison to Dreamcast actually was a lower resolution. We recently had a PS2 developer here a year ago who confirmed this.
What's funny is that Dreamcast is capable of rendering at least 800x600 internally (Ikaruga uses this mode) but its output is limited to 640x480p60 max due to the VGA standard.
Thats friggen awesome. But I need documentation sources.Quote:

Yeah, the VGA output is locked to 640x480p60. Ikaruga displays at 640x480p60 but you can see that there's something strange going on with its resolution. The game was designed for 480x640.
During the Dreamcast's lifetime there were all kinds of claims of "supersampling" being easy and not a performance hit. I haven't ever even seen a list of Dreamcast games that definitely use AA, much less super sampling. With the other console's trend toward line doubling-as-upscaling the Dreamcast probably just looks a little sharper because it was more frequently actually rendering at 640x480 rather than some lower resolution to save VRAM. I wonder if some emulator will let us see the rendering resolution some day, probably not.
Not due to the VGA standard. A VGA signal can carry much higher resolutions than that.Quote:

Yea I wasn't sure what to think of that. I'm using VGA on my computer, at 1600x900.Quote:
