Horizon: Zero Dawn PS4 Pro enhancements detailed
《地平线:期待黎明(Horizon:Zero Dawn)》官方发布 PS4 Pro 版优化细节
作为明年年初发售的大作,《地平线:期待黎明》自然也针对PS4 Pro 作出了大量的优化。今天游戏官方与Sony 联合公布了关于这款的作品在PS4 Pro 上的优化细节。
《地平线:期待黎明》主要使用了更高的抗锯齿技术,这将让PS4 Pro 用户在1080P 的显示器上得到接近4K 级别的画面质量。其次开发商还对作品的阴影质量、贴图质量进行了相应的优化,以便于让本作的画面表现更加优秀。事实上在PS4 的演示画面来看,《地平线:期待黎明》的画质就已经是高级精英级别,而本次针对 PS4 Pro 的优化将让本作的画质更加逼真。而使用4K 电视的玩家,则可以配合PS4 Pro 得到更惊艳的画质体验。
因为目前所有的PS4 都已经通过固件升级支持HDR,所以普通PS4 用户也可以得到更好的游戏体验(需根据电视机的需求)。《地平线:期待黎明》为PS4 独占游戏,预计发售时间为 2017 年 2 月 28 日。
How PS4 Pro Enhances Horizon Zero Dawn
Horizon Zero Dawn is an action RPG set in a lush, post-post-apocalyptic open world in which humanity is no longer the dominant species. Machines, not mankind, rule the Earth.
We’re very excited about HDR, 4K TVs, and PS4 Pro in general, but to be clear, the game we demonstrated at the past two E3s was running on standard PS4 hardware. We’re dedicated to making a game that looks great regardless of the model it’s played on; it will look beautiful on PS4, and will look even better on PS4 Pro — particularly if you own an HDR-compatible 4K TV.
As we showed at the PS4 Pro reveal event last September in New York City, the extra power of the new hardware allows us to get even closer to our vision for a lush and vibrant living world. The extra detail in the natural environment and the enhanced colors really add to the experience.
We’ve used the enhanced hardware of PS4 Pro to do some exciting things for Horizon Zero Dawn’s art style. In the end, it’s up to each developer to make its own decisions that align with the priorities of the title.
For us, Horizon Zero Dawn is all about scope, scale, and visual splendor. Though the game is technically post apocalyptic (or perhaps more accurately, post-post apocalyptic) we wanted to create a vision of nature reclaiming the Earth. PS4 Pro’s power afforded us a number of interesting possibilities to expand this vision even further.
For starters, for players who still possess standard 1080p HDTVs, we’re able to offer far better image quality. We’ve got a number of techniques at our disposal. The most logical one is supersampling. This is a very high-quality anti-aliasing technique, which basically means we internally render at a higher resolution (close to 4K) before shrinking it down to the final 1080p resolution. As our internal calculations are done at a resolution much higher than 1080p, more detail survives before we shrink it down to 1080p, resulting in smoother edges — virtually no jaggies — and a more stable image.
We’re also looking at enhancing the quality of our shadow maps and increasing the quality of our anisotropic filtering. This is a technique which increases the quality of texture sampling, resulting in more detailed environment textures. We still have to tweak these elements of the 1080p output quality for the final game, but we have quite a bit of power yet to play with.
In addition, Horizon Zero Dawn on PS4 Pro will fully support users with 4K TVs, outputting at a much higher resolution. We’re rendering 2160p checkerboard, which is a special technique that looks incredible on a 4K TV. You’re going to notice a ton of subtle details, from stitching on Aloy’s outfit, individual leaves and branches swaying in the wind, kilometers away in the distance, and more detail in all the machines and NPCs in the world.
Then there’s HDR, or high dynamic range, which is a brand-new feature that enhances the range of colors we can display. It’s very exciting and hard to explain as it’s something which most people haven’t seen before, so they don’t know what to expect. You can’t print it, it’s not in cinemas, your phone’s screen can’t do it. The only thing that you can compare HDR with is reality. We normally have to do a lot of work in the engine to take an internal high dynamic range image and then make it suitable to be displayed on a normal TV. A lot of color fidelity gets lost in the process. If you own an HDR-enabled TV, we don’t have to lose that data and you’re looking at the image in its full glory, with brighter and deeper colors, more contrast and vibrancy, in its pristine state. The benefits are truly awesome.
For me as a developer, the most exciting thing about PS4 Pro is that it provides a lot of extra processing power. It will be interesting to come up with different ways to put that additional horsepower to use — from finding more efficient ways to output at high resolution, to giving non-4K players more display options, and much more.
