How CD Projekt Red Got Cyberpunk 2077 Running on Switch 2

Cyberpunk 2077 on Switch 2 – The Technical Hurdles

Bringing Cyberpunk 2077 to the Switch 2 posed a significant challenge, given the game’s demanding hardware requirements. CD Projekt Red (CDPR) faced the task of optimizing a title designed for high-end PCs and consoles to run on Nintendo’s more modest hardware. The initial hurdles included understanding the Switch 2’s architecture and translating Cyberpunk’s complex systems to a new platform.

• CDPR had to re-engineer key elements of the game.
• The Switch 2 features less computational power than other platforms Cyberpunk is on.
• The team worked closely with Nintendo to ensure a smooth transition.

Early Collaboration with Nintendo

The groundwork for the Switch 2 version of Cyberpunk 2077 was laid in summer 2023 through discussions with Nintendo, during which CDPR was introduced to the new hardware. A small team was assigned to work directly with Nintendo engineers, fostering a close collaboration. This hands-on approach allowed CDPR to quickly assess the potential of the hardware and begin experimenting with optimization techniques.

Working directly with Nintendo was crucial due to the top-secret nature of the Switch 2. This allowed the team to have a close end-to-end work with Nintendo.

Engine-Level Modifications

Cyberpunk 2077 was built primarily for x86 architecture, whereas the Switch 2 utilizes a different architecture, necessitating fundamental changes at the engine level. This involved converting shaders from HLSL to GLSL and adapting to the unique processing capabilities of the platform. CDPR’s expertise with the game’s engine proved crucial in efficiently making these modifications.

Resource Management and Optimization

The Switch 2 presents a more constrained resource environment than other platforms, with fewer computational cores and shared resources with the operating system. This necessitated careful resource management, with CDPR optimizing various aspects of the game, such as crowd density and character detail levels, to maintain performance within the platform’s limits.

Leveraging NVIDIA’s DLSS Technology

To enhance visual fidelity and frame rates on the Switch 2, CD Projekt Red utilized NVIDIA’s Deep Learning Super Sampling (DLSS) technology. DLSS uses artificial intelligence to upscale lower-resolution images and generate additional frames, resulting in sharper visuals and smoother gameplay, particularly in handheld mode. This proved to be a vital tool in achieving a playable experience.

Storage and Memory Advantages

The Switch 2 benefits from faster storage solutions compared to the previous generation of consoles, primarily utilizing microSD Express storage. These storage solutions translate to faster loading times and improved streaming capabilities, eliminating the bottlenecks of mechanical hard drives. The increased RAM on the Switch 2 also contributes to smoother performance.

• Faster storage solutions and more RAM are two advantages over last-gen consoles.
• This results in faster loading times and improved streaming capabilities.

Gameplay Experience and Unique Features

While visual compromises were necessary, CDPR focused on delivering a solid gameplay experience on the Switch 2, including the Phantom Liberty expansion. The team also embraced the unique features of the platform, such as motion controls via the Joy-Cons and optional mouse support, enhancing the overall experience. Cross-save functionality allows seamless transition between PC and Switch 2 gameplay.
