The massive 1GB+ monster-sized tactics RPG by HyperDevBox called Spectral Souls has been updated with support for the nVidia Tegra 2 chipset now. This means that if you are lucky enough to have a Tegra 2 device already, and happen to own Spectral Souls, then you'll be seeing quite the performance boost.
While this game will run pretty good on non-Tegra devices, having Spectral Souls on a dual-core Android tablet and running optimized for dual-cores is going to make this game look and perform on a whole new level. If you haven't tried Spectral Souls yet and you do have a dual-core Android device, you might want to consider checking it out now. You can pick it up off the market for $14.47 which, if you've dropped the money on a Tegra 2 device already, isn't a whole lot to drop on a game.
