A better pitch would have been if you could test it on multiple platforms. For example, I have a Linux machine, so due to the relative lack of testers, I am more likely (statistically) of getting in.
Way to stay positive about your chances.
And I agree, I think they would indeed be selecting from a variety of testers. Your setup may not be as much the norm as mine likely is, so I am sure you would be near retroactively selected, just for that alone, if it is all that unique.
Me, I am sure I have a generic setup.
I am running on a (an old non VR ready) gaming laptop, running Windows 8.1, an older i7 and older Nivida chip. Other than not being VR ready, it can play many 3D games quite well. It has little trouble with most any 2014 game. No Man's Sky, is one It can't play, as a newer game.
So, I got something good (good enough to play this, I am sure), though not a stand-out setup.
Should be interesting to see if I get selected within the next few days. To those that do get in, cheers!
