Epic Citadel, a free tech demo, was an eye-opener that showcased what the Unreal Engine could pull on A4-enabled gadgets like iPad and iPhone 4. TouchArcade now uncovered Castlerama, another Unreal tech showcase that lets you explore lush environments with amazing detail. Developer Codenrama noted in the YouTube description that graphics could have been even better had they targeted the code for iPad 2 and iPhone 4 only. The reason? Those devices sport 512MB RAM, twice their predecessors:
While developing Castlerama, we had to face the fact that newer devices such as iPhone4s and iPad2s are very different from their predecessors, iPhone3GSs and iPads, in that the former have twice as much memory. In order to have the app run on all devices, we had to compromise quite a bit, pushing the old devices to their limits (risking crash if other applications are left running) while keeping the new devices well behind their capabilities. In the future we believe we will have to develop two versions for each application.
Castlerama can be downloaded for free from the App Store. The universal binary works on all iOS devices and weighs in at 244MB. If you ask me, it’s an exciting example of high-quality games powered by the Unreal Engine coming our way.
