大家好,欢迎收听我们的科技播客。今天,我们要聊聊一个非常有趣的话题:RISC-V架构在游戏领域的最新进展。你可能听说过RISC-V,这是一种开源的、免版税的CPU架构,与主流的ARM和x86/x64 CPU相比,它还处于早期开发和采用阶段。但尽管如此,开发者们还是成功地在RISC-V PC上运行了上一世代的AAA级游戏《巫师3:狂猎》。
首先,让我们来看看他们是如何做到的。开发者使用了Box64、Wine和DXVK这些工具,通过Linux系统而不是Windows来模拟x86指令。他们在博客中详细记录了这一过程,并在YouTube上上传了游戏运行的视频。虽然在这种条件下,《巫师3》只能达到可怜的15帧,但能够启动并运行在RISC-V上,已经是技术上的重大成就,预示着开源架构的美好未来。
然而,运行《巫师3》在RISC-V上还存在一些显著问题。主要挑战在于x86_x64 CPU指令的翻译。游戏和其他软件依赖特定的CPU指令,当这些软件必须在另一种硬件架构上运行时,新的架构需要能够替代或复制这些指令。在RISC-V架构上模拟x86的主要难题是将这些x86/x64 CPU指令翻译成RISC-V能够理解的东西。这导致大量的硬件能力被用于过度“翻译”原本简单的x86指令,这在RISC-V架构上变得复杂。
尽管如此,这一进展显示了未来可能的趋势:今天的科技巨头不会永远完全控制PC游戏市场。按照这种发展速度,一个有竞争力的RISC-V游戏PC可能在接下来的十年内,甚至更短的时间内上市。这不仅是对技术爱好者的鼓舞,也是对整个行业未来发展的一次重要预示。
