Forums - Microsoft - Xbox One will Double Performance with DirectX12

I thought MS had the best software engineers in the world...

Double theoretical performance, maybe. In real life it won't come close to that.

In some ways they do and in some ways they do not.I prefer Linux to Windows, but I prefer Windows Phones to Android Phones. There is nothing wrong with the software on the XBOne now. DX12 will probably give it a 5-10% boost. The system is fine other than a few weird design choices

I will believe it when I see the performance double. But to be honest it doesn't really matter to me, I am quite happy with the X1 as it is. (minus a few bugs/annoyances with kinect.)

This x1000.  

Seems like a load of marketing to me too, but no doubt DX12 should bring some improvements.  Even if 10%, still better than 0.

Also, regarding the bold.  I love Titanfall, and despite the studdering and screen tearing, still think it looks great.  The explosion effects make me feel like I'm in a movie.  I just wish you could ram the titans through buildings and such.  That would be even better...

All these threads need to be immediately locked. The idea that software can boost fixed hardware by double is impossible. They say the same thing about DirectX on PC but DX9 still has better performance than any of the newer ones....


Hey I am tired of this crap from MS as much as the next guy, but actually DX11 is a lot more efficient than 9.

Define efficient. It looks better with a small performance loss

 

If a game gives you the choice of DX9 or DX11 the DX9 version will run at a higher FPS than the DX11 version (with some graphics loss)

I agree, Titanfall looks great! And is very fun to play also. Titans being able to ram thorugh buildings would have been amazing!

With the current directX, firing draw-calls from the CPU is single-threaded. The performance boost mostly comes from using the cpu in parallel to fire draw-calls to the gpu.
Draw-calls are a performance killer. The new directX 12 technology raises the amount of possible draw-calls drastically.
This + some other nice features are going to raise the performance for all directX12 graphics card excessively. (that is - if you split your draw-calls to multiple threads)

Read what I wrote a few pages before. The "Draw call hell" does NOT exist on the XBox One. Listen to the talk at the recent Build conference. The ms hw guy made it very clear. There will be <5% speed increase because this part of DX12 was in the sdk right from the start.

? that would only make a difference if the GPU had more power. You could put 50 threads on a Pentium processor but an i7 would still crush it.
