DF:PS5没有RDNA2硬件特性之一VRS功能
It's also interesting to note that Xbox Series consoles use the hardware-based tier two VRS feature of the RDNA2 hardware, which is not present on PlayStation 5. VRS stands for variable rate shading, adjusting the precision of pixel shading based on factors such as contrast and motion. Pre-launch there was plenty of discussion about whether PS5 had the feature or not and the truth is, it doesn't have any hardware-based VRS support at all. However, developers can tap into the MSAA anti-aliasing hardware and exploit it to deliver something very similar to a tier one VRS solution. Metro Exodus does this on PlayStation 5, while Call of Duty Warzone does something similar on all consoles. In combination with Series X's extra GPU grunt, the use of variable rate shading may explain why the Microsoft console achieves higher resolutions overall. |
