SuperSampling DSR

SuperSampling (DSR)

Render Valheim's world at a higher resolution, then downsample it for smoother distant edges while the HUD and menus keep their normal output resolution.

Client only. No server installation is needed. Requires BepInExPack Valheim. This release targets Valheim 1.0.16 with Unity 6000.0.75f1.

Quick start

• Import this ZIP into your mod manager, or copy its BepInEx folder into the game folder.
• Launch the modded game and press F8.
• Select In-Game, choose 150%, and apply.
• Lower the scale if performance drops. Select Off to return to the game's rendering settings.

Higher scales use more GPU time and memory. The scale applies to both dimensions: 150% renders 2.25 times as many pixels; 200% renders four times as many.

| Game output | Scale | World rendering | HUD and output |

| --- | --- | --- | --- |

| 1280 × 720 | 150% | 1920 × 1080 | 1280 × 720 |

| 1920 × 1080 | 200% | 3840 × 2160 | 1920 × 1080 |

| 3840 × 2160 | 200% | 7680 × 4320 | 3840 × 2160 |

Custom scales from 100% to 300% are supported, including decimals. Targets must fit the GPU's texture limit and the mod's 67,108,864-pixel cap. 4K at 200% fits that cap; 4K at 300% exceeds it. In-Game mode does not require an NVIDIA GPU.

Controls

| Shortcut | Action |

| --- | --- |

| F8 | Open or close settings |

| Left Ctrl + F8 | Emergency Off and display restoration |

| Escape in settings | Close settings and revert an unconfirmed display change |

Change shortcuts in BepInEx/config/mods.valheim.supersampling.cfg. AzuCraftyBoxes Fixes & Config also uses F8; remap one shortcut if both are installed.

Optional System DSR

Enable DSR/DLDSR in your driver's settings first, then select System DSR in the mod. Check the monitor's native reference, refresh the resolution list, and choose a higher mode. Select Keep within 15 seconds after it applies, or the mod requests the previous mode.

System DSR uses Windows exclusive fullscreen and resolutions the system already exposes. It cannot enable driver factors or identify whether a listed mode uses DSR, DLDSR or another driver feature. In-Game mode works without changing the display mode.

Keep UI at native size compensates Valheim's UI scaling during System DSR. Other mods with independent UI systems may need their own settings. Correct the native reference if your desktop already uses DSR or you change monitors.

Recovery and support

Display changes are saved to a recovery file before switching. Version 0.1.4 preserves the previous recovery file if a replacement write fails and improves cleanup when the plugin is disabled or display restoration fails. DSR is selected manually each launch; In-Game mode can resume automatically.

An unresponsive mode gets a 20-second application timeout. A saved recovery record remains until restoration is verified. After an interrupted DSR session, launch once with the mod still installed to restore the display before uninstalling.

In-Game rendering at 150% has been verified in a graphical client on Valheim 1.0.16. Driver DSR/DLDSR switching, VR, Vulkan and other framebuffer replacement mods have not been fully tested. Use the diagnostics panel to write a report if rendering fails, and include BepInEx/LogOutput.log when reporting a problem.

To update, close Valheim and replace BepInEx/plugins/ValheimSupersampling/ValheimSupersampling.dll; keep only one copy. Your configuration is retained. License and credits are included in LICENSE.
