📋 About This Mod
Valheim Upscaler
DLSS · FSR · XeSS · Frame Generation · Reflex
Before jumping to conclusions: this mod is not "just OptiScaler."
The DLSS implementation, rendering hooks, resolution scaling logic, Unity integration, and the overall framework are all part of this mod. OptiScaler is completely optional — if you only want native NVIDIA DLSS, you do not need it at all.
OptiScaler is supported solely to provide compatibility with additional upscalers (FSR, XeSS, or other vendor-specific solutions) on hardware that doesn't support native DLSS. It works by hooking into the interfaces exposed by this mod; it does not replace or implement the core functionality. Without this mod's rendering pipeline and hooks, there is nothing for OptiScaler to attach to in Valheim.
Requirements
The mod DLLs in this package are already laid out in the correct folder structure. You only need to download the following:
-
[]BepInEx 5. 4.x (x64)[/]
[]Streamline v2. 12. 0 — everything needed is under bin/x64/: the sl. plugins, nvngx_dlss.dll, and nvngx_dlssg.dll[/]
[]OptiScaler (optional) — intercepts the mod's DLSS call; the backend (DLSS / FSR 3. 1 / XeSS / FSR4) is picked in its overlay[/]
[]nvngx_dlssnr.dll file from the mod page and choose either the Normal variant or the RTX 40 Series variant. RenoDX is not required, this step is completely optional and only needed if you want to test DLSS 5.[/]
⚠ Warning: RTX 40 / 50 series users: do not install OptiScaler for frame generation — it conflicts with this mod's native DLSS-G implementation. Use the native DLSS-G path (F11) instead. All other GPUs (RTX 20/30 series, AMD, Intel) still need OptiScaler for frame generation via OptiFG.Installation

This Valheim BepInEx mod replaces the game's render-scale bilinear upscaling with AI upscaling via NGX, using OptiScaler to support DLSS, FSR, XeSS, and FSR4, with optional frame generation. It's for players with compatible GPUs who want sharper visuals and better performance, though it's new and unendorsed.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Brings modern AI upscaling to Valheim, which can boost performance and image quality.
- Supports multiple upscaling techs (DLSS, FSR, XeSS, FSR4) so you can use what your GPU supports.
- Optional frame gen could smooth out high-refresh gameplay if you have the hardware.
⚠️ Cons
- Zero endorsements and only 196 downloads—this is a fresh mod with no community vetting yet.
- Requires BepInEx and OptiScaler setup, which adds complexity for non-technical players.
For Valheim players with RTX or recent AMD/Intel GPUs who want sharper visuals and better FPS without sacrificing quality. Skip if you're on older hardware or prefer vanilla graphics.
💡 Beginner Tips
- Make sure you have BepInEx installed and configured for Valheim before adding this mod.
- Check your GPU's supported upscaling tech (DLSS for Nvidia, FSR for AMD/Intel) and enable the corresponding option in OptiScaler.
- If you enable frame generation, verify your monitor's refresh rate and VRR support to avoid screen tearing.
