Controls
One of the big differences between PC and console gaming is the availability of a mouse and keyboard. You expect it, so we're happy to confirm that the PC options screens let you remap all the default action bindings, with both primary and alternate bindings available simultaneously. Speaking of mice, we've made sure not to alter the sensitivity of high-end gaming mice by applying artificial mouse smoothing, and you can control sensitivity or toggle mouse acceleration in the options screen.

What's that you're mumbling to yourself? You prefer a console controller? Don't worry, traitor, your secret is safe with us. There are three separate controller layouts (Default, Marksman, and Retro), each of which support loads of configuration options. You can tweak aim assist, sensitivity, vibration, and look inversion. Are you a left-handed player? Go ahead and revel in your genetic superiority because all controller layouts support multiple analog-stick configurations: Default (Look on right stick, Move on left), Southpaw (opposite of Default), Legacy (for those GoldenEye fans), and Legacy Southpaw. And for those who truly yearn for an old-school feel, or who use special controllers for medical reasons, we even let you swap the left or right analog stick with the D-pad.

All UI's in the game are controllable via either keyboard and mouse or the console controller, and you can switch back and forth between the two input paradigms without ever pausing the game.

Graphics
I know, I know. Why discuss Controls first when we all know that Graphics Options is the first place you'll be visiting? Because patience is a virtue. And it's worth the wait.

This time around, we've fully embraced widescreen gaming. With our implementation of “horizontal plus” widescreen support, the wider you go, the more you'll see of Columbia's gorgeous vistas. And for the true aficionado, we support multi-monitor gaming with AMD Eyefinity, NVIDIA Surround, and Matrox TripleHead2Go. You'll also have separate controls for aspect ratio, resolution, and display mode (fullscreen, windowed, and fullscreen windowed).

We have six different graphics presets, from “Very Low” to “Ultra,” providing a wide range of quality-versus-performance options. Gamers who want to tweak those further can switch to a Custom configuration, which gives you control over anti-aliasing, texture detail, texture filtering, dynamic shadows, post-processing, light shafts, ambient occlusion, and object level of detail. Many of these options have setting levels that are only available under DX11.

That's right-BioShock Infinite is a DX11 game. Though you only need DX10-compatible hardware to play, having a DX11 graphics card gives you access to contact-hardening dynamic shadows, diffusion depth of field, high definition ambient occlusion and optimized antialiasing. Each of these features was developed in close collaboration with AMD's graphics experts to take maximum advantage of modern DX11 hardware.

Finally, to show off all of that glorious PC pixel-pushing power, we're shipping with unadulterated, full-resolution textures right in the box. You may not enjoy the three-DVD install, but we hope you will appreciate the jaw-dropping detail our amazing team of artists lavished on the game.

Gaming Wherever, Whenever
So you have a sweet gaming rig at home, but what about when you're on the road for work, taking a break between classes, or visiting your relatives? We know that you appreciate being able to bring your gaming with you and may not always have a beefy machine available. We've worked hard to include graphics options that scale both up and down, so you can play BioShock Infinite even on less powerful setups with integrated graphics.

Speaking of bringing your gaming with you, did I mention that the game is on Steam, with Steam Cloud support? You'll be able to get your BioShock Infinite fix no matter where you are, and your saved progress travels with you.

Likewise, if you just bought an 80-inch TV and prefer to take your PC gaming to the couch (or is it a “love seat”?), we've got you covered with support for Steam's Big Picture mode. Heck, with a wireless controller and a good insurance plan, you can even play from your Jacuzzi.
