Minimum & recommended PC specifications
Hardware requirements published in the Simon3Sarkis/super-odyssey-pc-recomp documentation for Windows 10/11, Linux x86_64 and Steam Deck:
- Operating system
- Windows 10 or 11 (64-bit) or 64-bit Linux with
glibc 2.35+(Ubuntu 22.04+, Fedora, Arch, SteamOS). - Processor (CPU)
- 64-bit x86_64 processor with AVX2 support (Intel 4th-gen Haswell or newer; AMD Ryzen / Zen or newer).
- Graphics card (GPU)
- Vulkan 1.3 capable GPU with updated drivers (NVIDIA GeForce RTX/GTX, AMD Radeon RDNA/Polaris+, Intel Arc, Steam Deck APU). NVIDIA RTX required for DLSS/DLAA; FSR 1 and SMAA work on all Vulkan 1.3 GPUs.
- System memory (RAM)
- 8 GB RAM minimum; 16 GB RAM recommended (especially during parallel C compilation and shader precompilation).
- Storage space
- Around 12 GB of free space for the extracted game library (
extracted/), precompiled shader cache (cache/), and source dump. - Game files
- Your own extracted
exefsandromfsfolders from Super Mario Odyssey 1.0.0 or 1.4.1 (full merged RomFS).
Graphics, upscaling & framerate options (F1 > Graphics)
Open the Dear ImGui top menu bar at any time with F1, Esc, or the controller Guide button to configure rendering and presentation:
| Feature | Hardware Scope | Available Modes & Behavior |
|---|---|---|
| Internal Resolution Scale | 0.5x (960x540) to 4x (7680x4320) | Includes 0.75x (1440x810, or 960x600 on Steam Deck 16:10), 1x (1920x1080), 2x (4K), 3x and 4x (8K). |
| NVIDIA DLSS & DLAA | RTX GPUs (Windows/Linux) | Presets: Quality, Balanced, Performance, Ultra Performance, plus native-resolution DLAA. |
| AMD FSR 1 | All Vulkan 1.3 GPUs | Spatial upscaling presets: Ultra Quality, Quality, Balanced, and Performance (default on Steam Deck Battery Saver). |
| Anti-aliasing (SMAA) | All Vulkan 1.3 GPUs | Enhanced Subpixel Morphological Anti-Aliasing when not using DLSS/DLAA. |
| Aspect Ratio & Ultrawide | 16:9, 16:10, 21:9, 32:9 | Enable Fill window under F1 > Graphics to expand the viewport across ultrawide and 16:10 monitors. |
| High Frame Rate Modes | 60 FPS, 90 FPS, 120 FPS, 120 Hz Interp. | Standard 60 FPS cap, experimental native 90 / 120 FPS gameplay ticks, or 120 Hz frame interpolation. |
Measured Steam Deck LCD benchmarks (v0.2.0)
In v0.2.0, upstream added automatic Steam Deck hardware detection and benchmarked the Cap Kingdom on an LCD Steam Deck (docs/linux.md):
| Hardware & Preset | Internal Resolution & Upscaler | Target Mode | Measured Frame Rate |
|---|---|---|---|
| Steam Deck LCD (Battery Saver default) | 960x600 (75% of 1280x800) + FSR 1 | 60 FPS cap | 53–60 FPS across the Cap Kingdom |
| Steam Deck LCD (High Frame Rate test) | 960x600 (75% of 1280x800) + FSR 1 | 90 / 120 FPS mode | ~78 FPS walking in open areas · ~55 FPS in Cap Kingdom town |
On desktop PCs, you can toggle the on-screen Performance Overlay (F1 > Graphics) to monitor live FPS and frame time graphs, or press F9 to write detailed single-frame diagnostics to SuperOdysseyRecomp.log.

Common questions
Why does the CPU require AVX2 support?
Both the bundled Zig/LLVM compiler output (odyssey_game.dll / libodyssey_game.so) and the lifted AArch64 NEON vector instructions target x86-64 AVX2/FMA instructions available on Intel Haswell (2013+) and AMD Zen (2017+) processors.
Should I use native 90/120 FPS or 120 Hz frame interpolation?
Native 90/120 FPS runs the game loop at a higher tick rate (experimental; on Linux it can trigger an opening cinematic crash tracked in Issue #15/#18). 120 Hz frame interpolation keeps the underlying game logic at 60 Hz while presenting interpolated frames for 120 Hz displays.
Why is RAM usage high on some systems (Issue #7)?
Initial shader precompilation and large kingdom asset caches allocate significant host memory. Ensure at least 8 GB of physical RAM (16 GB recommended) and keep the Windows page file enabled.
