The difference between what the game looks like when running in native 720p can be found below. It’s not rendering in bordered HD that’s for sure. Instead we can see that the game is actually rendering in 480p, and then being upscaled to 690p to form the final displayed frame.
Interestingly, the final output looks somewhat blurrier than what a 690p image would look like when occupying its space in a native 720p framebuffer. While the overall output resolution of the framebuffer is in fact 720p (1280x720) the gameplay segment itself is presented in 920圆90, being 1:1 mapped to ensure that the image isn’t being cut off.
The first thing you’ll notice, is that Sonic Adventure comes in a bordered 4:3 aspect ratio, with thick stripy bars on each side of the screen, and thin ones at the top and bottom. Unfortunately, the DX version also features far more in the way of potentially game-breaking collision glitches, and sloppy control issues, neither of which felt quite as bad in the standard DC game. And this is exactly what we get here, but with some additional tweaks and changes. However, on closer inspection it is clear that this re-release is a bizarre combination of the GCN version of the game (Sonic Adventure DX), minus the extra content, with the DC original’s title screen tagged onto the end of it.įor those of you who don’t know, Sonic Adventure DX featured a few graphical upgrades over the DC game, including specular highlighting on Sonic and the other main characters, reworked texturing, and a boost in overall framerate. On first impressions it looks like Sega has taken the liberty of porting and sprucing up the original DC version of the game. Although that fun quickly turned into investigating just how well this HD revision holds up for the latest IQGamer Tech Analysis. I have many fond memories of the original Sonic Adventure on the Dreamcast, so much so that I thought I’d invest in a copy of the recent PSN and XBL HD re-release of this Sega classic.
