REPO Fidelity — HD Graphics & Performance Mod for R.E.P.O.

Better than REPO HD. Better than vanilla. Graphics overhaul that goes both ways — squeeze more FPS on potato PCs or push visuals on high-end rigs. Auto-detects your hardware and picks the best settings. Full in-game settings menu. DLSS, FSR, SMAA, shadow control, the works.

Replaces REPO HD. Everything it does, plus DLSS, auto-benchmark, CPU/GPU-aware tuning, performance optimizations, and way more control. If you have REPO HD installed, remove it.

Vanilla vs REPO Fidelity

Environment

Vanilla	REPO Fidelity

Cleaner edges, better shadow quality, no more pixelated mess. Notice the grating detail and wall panels.

Up Close — Edges & Text

Vanilla	REPO Fidelity

Vanilla	REPO Fidelity

Hazard stripes, text, and fine geometry all render without the jagged staircase edges.

Lighting & Textures

Vanilla	REPO Fidelity

Vanilla	REPO Fidelity

Brickwork, candlelight, and shadow edges all sharpen up. Look at the wall texture and the base of the candle.

Object Detail

Vanilla	REPO Fidelity

Vanilla	REPO Fidelity

Surface detail on the vase and sharper edges on the clown figure. Shadows render properly instead of blocky artifacts.

Features

Upscaling & Anti-Aliasing

DLSS — NVIDIA AI upscaling. At 100% render scale, runs as DLAA (native-res AA)
FSR — AMD temporal upscaling, works on any GPU including Linux/Proton
SMAA — sharp edge-based AA, no ghosting, works everywhere
CAS sharpening — adjustable post-upscale sharpening

Quality Settings

Shadow quality (Low through Ultra) and shadow distance (5–200m)
Light render distance (vanilla caps around 30m)
LOD bias, anisotropic filtering, texture quality
Pixel light count (1–16 per object)
Fog distance, draw distance
Post-processing toggles (motion blur, chromatic aberration, lens distortion, film grain, bloom)

Performance Optimizations

Shadow budget — limits nearby shadow casters by distance, with smooth fade transitions. Prevents item-heavy scenes from tanking FPS
Tiered shadow resolution — scales shadow map size by light importance instead of one-size-fits-all 4K maps
Shadow cascades for directional lights — proper cascade distribution instead of a single shadow map stretched over the full distance
Kills shadows on zero-intensity lights (free FPS, zero visual impact)
GPU instancing on all materials (fewer draw calls)
Cached physics queries (less garbage collection pressure)
Disables unnecessary shadows on explosions, particle effects, animated lights
CPU patches: EnemyDirector loop throttling, NonAlloc physics replacements, SemiFunc result caching, PhysGrabObject iteration fix, LightManager allocation-free cleanup
CPU patches auto-enable based on frame time — active when your system needs them, dormant when it doesn't
All optimizations scale with preset — Ultra keeps full visual quality

Smart Auto-Benchmark

Runs on first launch, stores results in autotune.json — separate from your settings
Re-runs automatically when the mod updates or your hardware/resolution changes
Detects CPU vs GPU bottleneck — won't waste visual quality on settings that can't help
"Auto" preset uses the benchmarked profile. Other presets are never touched by auto-tune.
Re-run manually anytime from the settings menu

Presets

All presets adapt to your hardware. CPU-bound machines keep 100% render scale since dropping resolution wouldn't help FPS anyway. Potato through Medium use the game's native render system with zero pipeline overhead — upscalers only activate at High and above.

Preset	Render Scale	AA	Shadows	Target
Auto	Benchmarked	Benchmarked	Benchmarked	Auto-tuned for your hardware. Re-runs on mod update or hardware change
Potato	50%	Off	Low / 10m	Faster than vanilla. Cuts everything for max FPS
Low	50%	SMAA	Low / 20m	Near-vanilla FPS with cleaner image
Medium	75%	SMAA	Med / 30m	Big visual upgrade, no upscaler overhead
High	75–100%	DLSS/FSR	High / 85m	Premium. Upscaler handles AA
Ultra	100%	DLAA/FSR	Ultra / 150m	Maxed everything
Custom	Any	Any	Any	Tweak individually. Per-setting perf toggles

Settings

Replaces the game's Graphics page. All vanilla display settings (window mode, VSync, max FPS, gamma) plus every mod setting. Preset selector or go Custom.

Setting	Range	Default	Description
Preset	Auto–Custom	Auto	Quality level. Auto uses benchmarked profile
Upscaler	DLSS / FSR / Off	Auto	DLSS on NVIDIA, FSR on AMD/Intel, Off if CPU-bound
Resolution	Monitor-specific	Native	Output resolution. Filtered to your aspect ratio
Render Scale	33–100%	100%	Internal resolution before upscaling to selected resolution
Anti-Aliasing	SMAA / FXAA / Off	SMAA	Post-process AA (disabled when upscaler provides AA)
Shadow Quality	Off / Low / Med / High / Ultra	Varies	Shadow map resolution
Shadow Distance	5–200m	Varies	Max shadow render distance
Shadow Limit	0–50	Varies	Max nearby shadows. 0 = unlimited. Closest lights get priority
Pixel Lights	1–16	Varies	Per-object dynamic lights
LOD Bias	0.5–4.0	Varies	Level of detail distance
Texture Quality	Full	Full	Locked to full — R.E.P.O.'s textures are too small for mip reduction to matter
Anisotropic Filtering	Off / 4x / 8x / 16x	8x	Texture sharpness at angles
Light Distance	10–100m	50m	Max light render range
Fog Distance	1.0–1.1x	1.0x	Fog end distance multiplier
Mod Toggle Key	F5–F10	F10	Disables mod entirely for vanilla comparison

F10 (configurable) toggles the entire mod off for vanilla comparison — everything reverts including performance optimizations.

F11 runs the optimizer benchmark — measures vanilla vs GPU/GC optimizations vs full (GPU/GC + CPU patches). Results saved to optimizer_benchmark.txt.

Installation

Install BepInEx 5
Install MenuLib for the settings UI
Drop this mod in BepInEx/plugins/
Launch — benchmark runs automatically on first level

DLSS DLL is bundled. No extra downloads.

Coming from REPO HD?

Remove it. REPO Fidelity does everything REPO HD does:

Removes pixelation / upscales to native
Anti-aliasing (SMAA, plus DLSS/DLAA for NVIDIA)
Extraction point flicker fix
Plus: DLSS upscaling, auto-benchmark, CPU-aware tuning, shadow optimization, full settings menu, performance presets, 15+ configurable quality settings

Compatibility

Works alongside most mods — only conflicts with other render pipeline mods
MenuLib required for settings UI (soft dependency — mod works without it)
Singleplayer and multiplayer
Windows and Linux (Proton)

Known Issues

Switching presets rapidly can briefly flash a black frame
Tiny object shadow removal can't be restored mid-level (requires level reload)
