I originally bought an edTracker for use with Elite Dangerous. It's a box about the size of a matchbox that you attach to the top of your headphones and uses an accelerometer/gyroscope to give 3 axis headtracking (pitch/yaw/roll). I paid £30 for my prebuilt one and it's worth every penny. If you're a bit handy with electronics you can just buy the parts off them and build one yourself. I however am not This works in conjunction with a piece of software called opentrack, which emulates trackIr calls meaning that with RF2 you simply have to assign the look directions to the device (by looking left/right etc). It's that simple to set up. EDIT - You don't need to use Opentrack at all for RF2, just assign look left and right bindings with the edTracker. Well I got on track and tried it. Wow, what a difference headtracking makes. I play on a single screen so sometimes seeing the apex of a tight corner is near impossible (Silverstone - The Loop for example), but with this I can hit the apex nearly every time, as well as get the power down a lot earlier than before. I wanted to try headtracking but for me TrackIR is just way too expensive. The only downsides I can think for this device are that you have to attach something to your headphones, so not wearing any can be an issue. It also needs to be plugged in via usb so if you hate cables it's probably not your thing. https://edtracker.org.uk/ is the place to go if you're interested.
