RISC-V Breakthrough: The Witcher 3 Running on RISC-V Architecture

In an impressive feat, developers have managed to run the popular AAA game, The Witcher 3: Wild Hunt, on a PC powered by RISC-V architecture. Although RISC-V is still in its early stages of development and adoption compared to mainstream CPUs like ARM and x86/x64, this achievement showcases the potential of open-source architecture.

The developers utilized a combination of Box64, Wine, and DXVK to emulate x86 instructions and bridge the gap between RISC-V and Linux. In a detailed blog post, they explained the challenges of translating x86/x64 CPU instructions into something that RISC-V could understand. This process consumed substantial hardware power, as RISC-V architecture complicated what used to be simple x86 instructions.

While the ability to run The Witcher 3 on RISC-V is a significant technical accomplishment, it is crucial to manage expectations. The game currently achieves only 15 FPS on RISC-V, making it semi-playable but far from an immersive experience. Nevertheless, this achievement paves the way for future advancements in open-source architecture.

Last year, the same developers successfully achieved fully playable 2D games on RISC-V, such as Stardew Valley and World of Goo. To bring The Witcher 3 to RISC-V, they required a Milk-V Pioneer, a RISC-V PC with a PCIe slot, along with an AMD Radeon RX 5500 XT installation. This limited form of gameplay shows that RISC-V architecture is capable of handling last-gen AAA titles with the right hardware configuration.

At present, this breakthrough may not have a significant impact on the gaming market; however, it highlights the ongoing efforts challenging the dominance of big tech companies. Similar to the advancements in Windows on Arm and Proton on Linux, the development of a capable RISC-V gaming PC could be a reality within the next decade, disrupting the current landscape controlled by Microsoft, Intel, and AMD.

As the RISC-V community continues to push the boundaries of what is possible, the future of open-source architecture in gaming looks promising. Stay informed with Tom’s Hardware for more news and in-depth reviews.
