What are the exact specs? I've read the intel HD4000 as the minimum vid card for awhile now.
Part of the point of a beta is to determine stuff just like this... You played the beta, they collected statistics, decided your setup is too slow, and blocked it via install.
My video card: Intel(R) HD Graphics Family (I need 256mb dedicated RAM, I have a distant 64mb. Again, specs on paper, not in practice)
Everything else meets minimum specs.
My setup wasn't too slow, they game was never choppy, I never had an issue except maybe a drop to 25fps at some points(acceptable to me).
Either way, who are they to say whether or not I can play a game that I purchased? My computers performance affects no one else, but me. If it was a MMO of some kind, maybe a minor hit to everyone else (still haven't heard anything of that either). My performance affects only me, if this collected data determined if they think I can play it or not, then they should not have proceeded with the purchase, or notified me accordingly.
