Building a PC to play S21 at its best
Meeting the S21 minimum requirements (a Intel HD 4400 or GTX-750-Class (1 GB VRAM)) is enough to launch the game, but it won't give you high frame rates at 1440p or 4K. The recommended NVIDIA GeForce GTX 1060 is a solid target, and stepping up to a GeForce RTX 5070 Ti, RTX 5080 or Radeon RX 9070 XT gives you the headroom for ultra settings, ray tracing and high-refresh play. On mid-range cards, DLSS 4 and FSR frame generation can lift S21's frame rate substantially, while a flagship RTX 5090 drives 4K at maximum settings.
The processor matters just as much: pairing your graphics card with a Ryzen 7 9800X3D or an Intel Core Ultra, at least 16GB (ideally 32GB) of DDR5 RAM and a fast Gen5 NVMe SSD removes the stutter and long load times that can hold S21 back. For modern textures at 4K, aim for a GPU with 12–16GB of VRAM so you never run short.
The same premium components also decide whether your rig is VR ready: if you game in virtual reality on a Meta Quest 3, Valve Index or PlayStation VR2, a strong GPU and CPU are what hold a steady 90 FPS.
