So I bought Arma 3 Alpha(which is awesome so far) and I get a steady 50-60 fps with all high settings. My only issue is I'm getting these weird small black boxes flashing everywhere. I have tried reducing all GX setting and maxing them as well and with both settings I get the same results. I should note that this isn't the first time I have seen this. This also happened when I tried to run Deus Ex:HR in DX11(or 10 I can't remember) but it would go away when I would use DX9(or 10, whatever was under the max DX version usable). This also happens in Crysis Warhead. Other games like Far Cry 3, Skyrim, and The Witcher 2 run flawlessly. I have run other games in DX11 and not had this happen. And yes my drivers are up to date.
Here is a video of it for your viewing pleasure:
