My issue with win 10 is the possibility that they will require all software to be purchased from Microsoft in the future. ie "Its a one fit all solution, therefore we need control of the software to make sure it fits".
I would like to know that Steam has a future with Win 10, however I am not confident it will.
To to summarize:
DirectX 11: Your CPU communicates to the GPU 1 core to 1 core at a time. It is still a big boost over DirectX 9 where only 1 dedicated thread was allowed to talk to the GPU but it’s still only scratching the surface.
DirectX 12: Every core can talk to the GPU at the same time and, depending on the driver, I could theoretically start taking control and talking to all those cores.
That’s basically the difference. Oversimplified to be sure but it’s why everyone is so excited about this.
The GPU wars will really take off as each vendor will now be able to come up with some amazing tools to offload work onto GPUs.
Assuming you’re remotely technical, the change from DirectX 11 to DirectX 12/Mantle changes are obvious enough that you should be able to imagine the benefits. If before only 1 core could send jobs to your GPU but now you could have all your cores send jobs at the same time, you can imagine what kinds of things can become possible. Your theoretical improvement in performance is (N-1)X100% where N is how many cores you have. That’s not what you’ll really get. No one writes perfect parallelized code and no GPU is at 0% saturation. But you get the idea.
Did you make it full screen? Doesn't look much different to me...
Possiblity of stacked VRAM with Mantle/DX12 in the future.
