At this point, the game already runs quite well. We wouldn't say it runs at a rock-solid 60fps, but it's certainly smooth enough that no one will be complaining. Given the amount of detail and number of particle effects happening at any one time, this is fairly impressive, especially for a first-generation PS3 title.
Call of Duty 3 will make pretty good use of the PlayStation 3's SIXAXIS controller, allowing you to use the pad's 3D spatial recognition to perform a number of tasks. For instance, if you want to perform a melee attack and take out an enemy soldier with the butt of your rifle, you quickly twist the controller horizontally. At one point you'll need to use the controller like an oar to row a boat, and when you set an explosive on an object, you'll actually need to twist the controller to set it and quickly thrust it to ignite the detonator. Cool stuff, and we're pretty sure this isn't all that we'll see.
While most of what we saw looked pretty promising, it wasn't perfect. For one thing, texture detail in certain spots leaves a bit to be desired at this point. The ground, especially when rocky, looked a little more low-res than we'd expect from a next-gen title. Weapon textures weren't as detailed as we'd have liked either, and the ones with wooden components especially stood out.
