I was wondering if it would be beneficial to be on the windows 10 insider build to test halo reach since I know beta graphics drivers are available through it. If so what branch should I choose.
As long as you sign up for halo insider here and fill out all info, dxdiag and link your steam you are good to go my friend.
I don’t think so, in fact I think it’d be better to be on a stable build of Windows.
They never mentioned that anywhere around the sign-up, so you don’t need it.
