Capcom Unity offers side-by-side comparisons of the original Resident Evil 4 and Resident Evil 4 HD, the recently announced improved edition of the survival/horror sequel, which is coming to Windows PCs next month. They show the impact of the game's new high definition textures compared to the cruder look of the original, saying users can switch on the fly between SD and HD graphics via a menu toggle. They also note that for those with high-end systems, extreme resolutions are available, if not officially supported: "And while 1920x1080 is the official supported resolution, you can crank things up to 2560x1600 or 2560x1440 if ya like - though be aware these aren't formal suggestions so performance isn't assured. We've had it running great at those sizes, but stick to 1920x1080 for optimal Plagas punishment." They also offer links to this trailer of the HD edition, showing it cranking along at 60 frames per second.
