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, 21:9 / 32:9 / 16:10 / 4:3 aspect-ratio support, FOV slider, the works.

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

v1.6.3 — 16:10 / 4:3 / 5:4 aspect support. The same un-squashed world-view path that's been there for 21:9 / 32:9 since 1.6.0 now also kicks in for narrower-than-16:9 panels. If your monitor is 1920×1200, 1680×1050, or any 4:3 / 5:4 mode and the game was letterboxing top and bottom, that's gone. Plus a fix for the < > arrows on the in-game graphics sliders — clicks now register, they were silently dead before.

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

Ultrawide & Field of View

• Full aspect-ratio support — 21:9, 32:9, 16:10, 4:3, 5:4 — world view fills the full screen instead of being squashed into a centered 16:9 box. Wider panels lose the side letterbox; narrower panels lose the top/bottom letterbox. Post-processing (vignette, bloom, screen flashes) extends across the full aspect, HUD positioning untouched so other mods that hook the UI hierarchy still work
• Aspect-aware default FOV — 16:9 stays at vanilla, 21:9 lerps up to ~80°, 32:9 hits 90°. 16:10 and narrower keep vanilla FOV (already covers what HOR+ shows). Slider override (0–110°) wins when set
• Vertical FOV slider with smooth animation between values
• Title-screen polish on ultrawide — menu camera narrows to hide the world edge past the truck, fog tightens to keep distant scene assets fading inside fog rather than popping at the rolling-treadmill despawn line
• F10 vanilla 16:9 compare view for side-by-side comparison without losing your saved resolution
• Resolution dropdown lists native-aspect modes plus synthesized 50/67/75/83% downscales so 21:9 / 32:9 panels aren't stuck with two or three Windows-reported entries

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.

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.

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

F11 toggles the performance optimization layer on and off. Unlike F10, the visual layer (upscaler, AA, shadow quality) stays active — only the per-frame hacks (tiny renderer culls, shadow budget, CPU patches, etc.) revert to vanilla.

F9 runs the cost probe — a ~90s sweep that measures per-marker frame cost, per-camera render time, scene composition, and a preset × fog × upscaler comparison matrix normalized to Ultra + DLAA + fog 1.0×. Writes frame_cost.txt and copies the report to the clipboard. Off by default — enable F9 Cost Probe in the Graphics menu to arm it.

Installation

1. Install BepInEx 5
2. Install MenuLib for the settings UI
3. Drop this mod in BepInEx/plugins/
4. 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
