视频说内置DX12 ,原来pc上要上千个指令去运行DX12 天蝎只要11个指令,在游戏内表现就是原生DX12游戏只消耗 ...
很可惜,不属实。这个技术只是节省cpu资源,后面gpu执行的真正的渲染部分该怎么样还是怎么样。
Processing draw calls - effectively telling the graphics hardware what to draw - is one of the most important tasks the CPU carries out. It can suck up a lot of processor resources, a pipeline that traditionally takes thousands - perhaps hundreds of thousands - of CPU instructions. With Scorpio's hardware offload, any draw call can be executed with just 11 instructions, and just nine for a state change.
"It's a massive win for us and for the developers who've adopted D3D12 on Xbox, they've told us they've been able to cut their CPU rendering overhead by half, which is pretty amazing because now the driver portion of that is such a tiny fraction," adds Goossen. |
