Nvidia announced the Tegra 4 mobile processor here at CES this week, and they were using a name game called Blood Sword to show it off. With this kind of power under the hood it's easy to forget you're playing a mobile game.
I played an early demo of hacky-slashy Diablo clone Blood Sword on a Tegra 4-powered mystery tablet. It's a fun game, though nothing to write home to the folks about. What was notable was the lighting and particle effects coming off of my spells, or from fire pits. Lighting effects were on par with some console games, though it didn't hit the mark of some of the big franchise stuff. But overall: very nice.
This tablet was docked and connected via HDMI to a television, letting me play Blood Sword with an Xbox 360 controller. After getting into some nasty messes and boss fights, I found myself forgetting that I was playing a tablet. The framerate and resolution were there for sure. If this early game demo is any indication, the Tegra 4 is a very capable processor.
