As good as a mouse, same precision but it does take a lot of practice and a strong arm because of the physical feedback it can give. so yeah that + a rift for total immersion is very tempting.
the issue is a rift will want you to turn 360 and that's a fixed device, something more like that floaty set of controls (razer is it) is more like what you need.
ah yeah, well i am going to get a rift, buuuut i will wait for a couple of revisions anyway, and read/watch plenty of reviews. Thanks for your input though
