索尼将 AI 图形超分辨率技术引入普通版 PS5
Sony is launching a new AI upscaling technology specifically for the regular PS5. The new tech, called Quick Spectral Super Resolution (QSSR), is a “new performance tier of AI upscaling” that’s a result of Sony’s Project Amethyst work with AMD, according to a blog post.
索尼正在为普通版 PS5 推出一项全新的 AI 超分辨率技术。根据官方博客文章，这项名为“快速光谱超分辨率”（Quick Spectral Super Resolution，简称 QSSR）的新技术是索尼与 AMD 合作的“紫水晶计划”（Project Amethyst）的成果，被定位为“AI 超分辨率的新性能层级”。
Sony says that PlayStation Spectral Super Resolution (PSSR), which is available on the PS5 Pro, “remains the gold standard,” and in Digital Foundry’s early hands-on with the tech, it does seem that QSSR isn’t as fast as PSSR because the PS5 doesn’t have dedicated machine learning silicon. As a result, you should probably expect closer to an upscaled 1440p resolution on PS5 instead of the upscaled 4K on PS5 Pro.
索尼表示，目前应用于 PS5 Pro 的“PlayStation 光谱超分辨率”（PSSR）技术“依然是行业金标准”。据 Digital Foundry 对该技术的早期上手体验显示，由于普通版 PS5 缺乏专用的机器学习芯片，QSSR 的运行速度确实不如 PSSR。因此，在普通版 PS5 上，用户可能更多会体验到接近 1440p 的超分辨率效果，而非 PS5 Pro 上的 4K 超分辨率。
“On PS5 Pro, developers almost uniformly output to 4K and adjust render resolution beneath it,” Sony principal graphics R&D engineer Daniel Craig told Digital Foundry. “On PS5, teams have to be more flexible, tuning not just render resolution, but also their intermediate and final presentation targets depending on the graphics mode.”
“在 PS5 Pro 上，开发者几乎统一以 4K 分辨率输出，并在此基础上调整渲染分辨率，”索尼首席图形研发工程师 Daniel Craig 在接受 Digital Foundry 采访时表示，“而在 PS5 上，开发团队必须更加灵活，不仅要调整渲染分辨率，还要根据不同的图形模式调整中间及最终的呈现目标。”
But Craig also said that QSSR is “fundamentally a drop-in replacement for titles that already support PSSR” after only a few days of tuning, making it likelier that PS5 developers will take advantage. The tech will be “offered broadly to all PlayStation developers,” Sony says.
但 Craig 同时指出，对于已经支持 PSSR 的游戏来说，QSSR 在经过短短几天的调试后，基本上可以实现“即插即用”的替换，这使得 PS5 开发者更有可能采用该技术。索尼表示，这项技术将“向所有 PlayStation 开发者广泛提供”。
Marvel’s Wolverine and Ghost of Yōtei will be the first games to take advantage of QSSR, and are getting patches today to offer the tech as “an additional graphics option on PS5.” (Ghost of Yōtei Complete Edition also launches today.) Here are a couple videos from Sony showing off how QSSR looks in those games, and it appears to make graphics a little bit sharper.
《漫威金刚狼》（Marvel’s Wolverine）和《羊蹄战鬼》（Ghost of Yōtei）将成为首批采用 QSSR 的游戏，它们将于今日获得更新补丁，将该技术作为“PS5 上的额外图形选项”提供。（《羊蹄战鬼》完全版也于今日同步发售。）索尼发布了几段视频展示了 QSSR 在这些游戏中的表现，画面看起来确实更加锐利了一些。
Digital Foundry writes that “the potential here is remarkable: low resolution and poor upscaling have impacted so many titles in this generation, but QSSR could make a big difference.”
Digital Foundry 评论道：“这项技术的潜力令人瞩目：低分辨率和糟糕的超分辨率效果曾影响了本世代的许多游戏，但 QSSR 或许能带来巨大的改观。”
