|---------|----------------|
| Ultra‑Sharp Terrain | No extra steps – all terrain tiles (soil, stone, sand, water) are automatically rendered at 4K. |
| High‑Resolution UI | UI scaling is handled by RimWorld; the icons simply look crisper. |
| Customizable Texture Packs | The Textures/Overrides sub‑folder allows you to drop your own PNGs (named exactly as the original) to create personal variants. |
| Dynamic Weather Particles | No toggle needed; the mod replaces the particle sprites used by the built‑in weather system. |
| HD Portraits | Colonist and animal portrait frames are now 4K; you can still use the “Portrait Editor” mod to replace them manually. |
| Performance Options | In the Options → Graphics menu you can set “Texture Quality” to High (default) or Ultra (forces the engine to keep the full 4K mip‑level, useful on high‑VRAM GPUs). |
Cause: Your GPU lacks VRAM. 4K requires 6GB+ VRAM for gaming.
Fix: Use in-game resolution scaling (e.g., 50% of 4K = 1080p rendered, 4K output). This gives you a sharper UI without the rendering cost. rim4k full
To achieve "Rim4K Full" status, a dash cam must contain specific hardware. You cannot software-patch poor optics. Here is what the ideal "Full" spec looks like: | Feature | How to Access | |---------|----------------|
Here is the reality check. Recording at "Full" bitrate (60-100 Mbps) eats storage for breakfast. Cause: Your GPU lacks VRAM
Cause: Windows is actually rendering at 4K but the monitor is scaling it down to 1080p internally.
Fix: Disable GPU scaling and enable "Integer Scaling" if available. Or check your monitor's OSD for "1:1" pixel mapping.
Cause: Windows replaced the modified driver.
Fix: Re-run CRU or re-apply the custom resolution in NVIDIA/AMD settings. Do not re-download random patches.
Most budget "4K" cameras use a 5MP sensor that interpolates up to 8MP. A true Full 4K camera uses a native 8MP sensor.
