节选自： <Here’s how Intel doubled Arc GPUs’ performance with a simple driver update>
Originally, Intel used D3D9on12 for DX9, which is a translation layer that uses DirectX 12 to understand DirectX 9 instructions. Petersen said he believes Intel “did the right thing at the time,” but D3D9on12 proved to be too inefficient. Performance was left on the table, with less powerful GPUs sometimes offering twice the performance of Intel’s graphics cards in DX9 games.
最初，英特尔为DX9使用D3D9on12，这是一个翻译层，使用DirectX 12来理解DirectX 9指令。彼得森说他相信英特尔 "当时做了正确的事情"，但事实证明D3D9on12的效率太低。性能被搁置在桌面上，性能较差的GPU有时在DX9游戏中提供两倍于英特尔显卡的性能。
Intel essentially started from scratch, implementing native DX9 support and leverage translation tools like DXVK — a Vulkan-based translation layer for DX9. And it worked. In Counter-Strike Global Offensive, I measured around 190 frames per second (fps) with the launch driver and 395 fps with the latest driver; a 108% increase. Similarly, Payday 2 saw around a 45% boost going from the launch driver to the latest version with the Arc A750 based on my testing.
英特尔基本上从头开始，实施原生DX9支持，并利用DXVK等翻译工具--一个基于Vulkan的DX9翻译层。而这也是成功的。在《反恐精英全球攻势》中，我测得推出的驱动程序的帧数约为每秒190帧，而最新的驱动程序则为395帧；增幅为108%。同样，根据我的测试，《发薪日2》在使用Arc A750的情况下，从启动驱动到最新版本，大约提升了45%。
DX9 was the killer for Intel’s GPUs at launch, but there are still performance optimizations on the table. Petersen made that clear: “Compared to where we are and that theoretical peak, there’s still quite a big gap.”
DX9是英特尔GPU推出时的严重问题，但现在仍需要性能优化。彼得森明确表示："与我们现在的情况和理论上的峰值相比，仍有相当大的差距。"
The new frontier isn’t DX9, though. It’s DX11. “I do think, especially for DX11 titles, there’s more headroom out there and we’re going to continue to work on it,” Petersen said. “DX12 is going to be more like a labor of love for forever because it’s a little bit more fine-grained, and it’s going to be a per-title kind of slog to make all those wonderful. But I do think there’s still an uplift ahead of us, and it’s more than you’ll typically see with a driver.”
不过，新的领域不是DX9。它是DX11。"我确实认为，特别是对于DX11游戏，有更多的空间，我们将继续努力，"彼得森说。"DX12将更像一个永远的爱的劳动，因为它有一点更精细，这将是一个每个标题的一种努力，使所有这些精彩。但我确实认为在我们面前仍有一个提升，它比你通常看到的驱动程序要多"。
One example of that is Warframe, where Intel claims upwards of a 60% boost in its latest driver against the launch driver. Although there isn’t a broad stroke Intel could make to help all DX11 titles, Petersen explained that DX11 is still more high-level than DX12. “While DX11 is not as thick as DX9, it’s still got quite a bit of work to be done for that optimization.”
这方面的一个例子是Warframe，英特尔声称其最新的驱动程序比推出的驱动程序提高了60%以上。虽然英特尔没有一个广泛的笔触来帮助所有的DX11游戏，但彼得森解释说，DX11仍然比DX12更高级。"虽然DX11不像DX9那样厚重，但它仍然有相当多的工作要做，以进行这种优化。"
XeSS is a great tool, but it lacks in a couple areas: game support and sharpness. Intel has been adding support for new games like Hogwarts Legacy and Call of Duty: Modern Warfare 2, but it’s going up against the years of work Nvidia has had to add DLSS to hundreds of games. Intel hopes implementing XeSS in these games will be an easy road for developers, though.
XeSS是一个伟大的工具，但它在几个方面有所欠缺：游戏支持和清晰度。英特尔一直在增加对新游戏的支持，如《霍格沃茨传奇》和《使命召唤：现代战争2》，但它要面对的是Nvidia多年来为数百个游戏添加DLSS的工作。不过，英特尔希望在这些游戏中实施XeSS对开发者来说将是一条简单的道路。
As Petersen explained, “[DLSS and XeSS] both rely on, you know, effectively certain types of data coming from the game to a separate DLL file. Same as XeSS. And we’ve kind of got the advantage of being a fast follower because, obviousl,y they were there first. So we can make it very easy to integrate XeSS.” This backbone is what has enabled modders to splice AMD’s FidelityFX Super Resolution into games that only support DLSS. The same is theoretically possible with XeSS.
正如Petersen所解释的，"[DLSS和XeSS]都依赖于，你知道，有效地将某些类型的数据从游戏中传到一个单独的DLL文件。和XeSS一样。我们有一种成为快速追随者的优势，因为很明显，他们是第一个出现的。所以我们可以非常容易地整合XeSS。"这条主干线使修改者能够将AMD的FidelityFX超级分辨率拼接到只支持DLSS的游戏中。理论上，XeSS也可以做到这一点。
One area I pressed on was a driver-based upscaling tool, similar to Nvidia Image Scaling or AMD’s Radeon Super Resolution. Petersen and Faiz were again careful to not promise anything, but they noted that it’s “not technically impossible.” That would fill in the gaps Intel currently has in its lineup, but we might not see such a tool for a while (if at all).
我追问的一个领域是基于驱动的升分辨率工具，类似于Nvidia的NIS (Nvidia Image Scaling)或AMD的RSR (Radeon Super Resolution)。Petersen和Faiz再次小心翼翼地没有做出任何承诺，但他们指出，这 "在技术上并非不可能"。这将填补英特尔目前在其产品线上的空白，但我们可能在一段时间内不会看到这样的工具（如果有的话）。
The other area is softness. Compared to DLSS, XeSS is usually not as sharp. I assumed this just a difference in the amount of sharpening applied, but Petersen said that’s not the case. “I think it’s a common problem, and I attribute most of the softness that you see today in certain cases as being, you know, an art style that’s not accurately reflected in the training set that we’re using for our model,” Petersen said. “And that will obviously change over time in new versions of XeSS.”
另一个方面是锐度。与DLSS相比，XeSS通常没有那么尖锐。我以为这只是应用的锐化量的不同，但彼得森说情况并非如此。"我认为这是一个普遍的问题，我把你今天在某些情况下看到的大部分柔软性归结为，你知道，一种艺术风格没有准确地反映在我们用于模型的训练集中，"彼得森说。"而这显然会随着时间的推移在XeSS的新版本中发生变化。"

不过那时候vkd3d应该不成熟
