Building a PC to play Undertale at its best

Meeting the Undertale minimum requirements (a 128MB) is enough to launch the game, but it won't give you high frame rates at 1440p or 4K. The recommended 512MB 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 Undertale'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 3GB (ideally 32GB) of DDR5 RAM and a fast Gen5 NVMe SSD removes the stutter and long load times that can hold Undertale 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.
