Cyberpunk 2 / Polaris confirmed for 2027 — inside the CDPR tech stack

Unreal 5.4 with custom RT pipeline, 520 engineers full-time, day-one Linux SKU. The handheld build is the engineering signal that matters most.

CD Projekt Red dropped the first real Cyberpunk 2 / Polaris technical details: Unreal Engine 5.4 with a custom path-traced GI pipeline, V returns as protagonist with a mid-campaign character handoff, 520 engineers full-time, and a confirmed 2027 ship window.

A native Linux SKU at launch is a structural commitment, not a marketing line. It signals that CDPR expects Steam Deck and Steam-OS handhelds to carry meaningful unit share across the title lifecycle. Vulkan-first rendering pipelines and Proton-aware shader caching are the engineering choices that cascade out of that decision.
