Frequently asked questions

Which GPU do I need for Redream?
The minimum GPU score for Redream is 600 (FPSHQ scale). The most affordable suitable card is Zotac Trinity GeForce GTX 950; rendering at 2–3× resolution needs ×2.2 headroom — the Palit GameRock GeForce GTX 980 level and up. The project officially requires: OpenGL 3.1.
Which CPU do I need for Redream?
The minimum CPU score is 1,500: 438 of 456 catalogue CPUs pass it. Official requirements: x86-64 / ARM64 · 2+ cores / 4 recommended. Emulation depends on per-core performance rather than the core count.
How much RAM does Redream need?
Per the Redream documentation: minimum 2 GB, recommended 4 GB. The emulator keeps the game image and shader cache in memory, so a RAM shortage causes stutter during shader compilation.
Which operating systems does Redream support?
Redream runs on: Windows, Linux, macOS, Android, Raspberry Pi. Graphics APIs: OpenGL. On Windows, Vulkan is usually faster (if your GPU supports it); on Linux it is Vulkan/OpenGL only.
Can my PC run Redream?
Pick your GPU and CPU in the "Can my PC run it" block above: the page compares their scores with the Redream minimum (GPU 600, CPU 1,500) and shows the headroom. ×1.4 or more means comfortable play at the console's native resolution.
Is Redream still updated?
Yes, Redream is an active project; status last checked Oct 4, 2026. Official site: https://redream.io/.

Methodology and sources

This page uses the FPSHQ database: the GPU and CPU catalogue with synthetic benchmark scores, official game system requirements, FPS measurements from users of the FPSHQ app and the FPSHQ performance model. Calculated values are estimates, not a measurement of your exact configuration: the real result depends on drivers, settings and the rest of the hardware. More about the methodology →
