PC system requirements
115 GB on an SSD. TPM 2.0 and Secure Boot are required. One GPU line conflicts between the blog and Steam.
From my notes. I put the September PC blog next to Steam app 4435490. RAM tiers match: 8 GB minimum, 16 GB recommended, 32 GB for the ray-traced ultra list. The NVIDIA recommended card does not match, so I am printing both names instead of picking a winner.
Minimum and recommended
Minimum: Windows 10, Ryzen 5 1400 or Core i5-6600, 8 GB RAM, and a Radeon RX 470, GeForce GTX 970, GTX 1060 or Arc A580 with 3 GB of VRAM. The CPU needs AVX.
Recommended: Windows 11, Ryzen 5 3600 or Core i7-8700K, 16 GB RAM, and a Radeon RX 6600 XT, GeForce RTX 3060 Ti or Arc B580 with 8 GB of VRAM. Steam's page says RTX 3060, without the Ti. That conflict was still there on 23 October 2026.
Ray-traced ultra: Ryzen 7 3700X or Core i7-10700K, 32 GB RAM, and a Radeon RX 9070 XT or GeForce RTX 5070 Ti with 16 GB of VRAM. Intel Arc also wants Resizable BAR.
Security and upscalers
TPM 2.0 and Secure Boot are mandatory, and RICOCHET is the anti-cheat. A phone number may be required. DLSS, FSR and XeSS are the upscalers named in the PC blog.
Install timing is on preload and size.
Questions
How much space does the PC version need?
About 115 GB on an SSD.
Is a GTX 970 enough?
It is in the published minimum list, with 8 GB of system RAM.
3060 or 3060 Ti?
The official blog says RTX 3060 Ti. Steam says RTX 3060. Both lines were live on 23 October 2026.
