Frequently asked questions

Which GPU do I need for Demul?
The minimum GPU score for Demul is 900 (FPSHQ scale). The most affordable suitable card is Radeon RX 470; rendering at 2–3× resolution needs ×2.2 headroom — the Radeon Pro VII level and up. The project officially requires: Direct3D 11.
Which CPU do I need for Demul?
The minimum CPU score is 2,000: 409 of 456 catalogue CPUs pass it. Official requirements: x86-64, SSE4.1 · 2+ cores / 4 recommended. Emulation depends on per-core performance rather than the core count.
How much RAM does Demul need?
Per the Demul 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 Demul support?
Demul runs on: Windows. Graphics APIs: Direct3D 11. On Windows, Vulkan is usually faster (if your GPU supports it); on Linux it is Vulkan/OpenGL only.
Can my PC run Demul?
Pick your GPU and CPU in the "Can my PC run it" block above: the page compares their scores with the Demul minimum (GPU 900, CPU 2,000) and shows the headroom. ×1.4 or more means comfortable play at the console's native resolution.
Is Demul still updated?
No, Demul has "legacy" status: no new versions are released. Consider the active alternatives for Dreamcast / Naomi in the "Other Dreamcast / Naomi emulators" list above.

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 →
