REPOFidelity

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

Better than REPO HD. 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 aspect-ratio support, and an FOV slider.

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.

A note from Vippy

After way too long of a break, I'm finally back and working on these again:D Every one of my mods just got a full pass: bugs fixed, reports read, a few things I'd always meant to do. New builds and fixes land in Vippy's Discord before they hit, so come hang out. Thanks for sticking around.

v1.7.0: experimental RepoXR (VR) support. The HD upscaling pipeline used to break VR stereo rendering, each eye ended up looking the wrong way. REPOFidelity now detects a VR headset and stands its camera pipeline down (no upscaler, no FOV or ultrawide override). The performance optimizations keep running, so VR still gets the extra frames. Raise VR render resolution with RepoXR's own CameraResolution setting. This is new and only lightly tested; if something looks off in VR, open an issue.

Vanilla vs REPO Fidelity

Environment

VanillaREPO Fidelity

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

Up Close - Edges & Text

VanillaREPO Fidelity

VanillaREPO Fidelity

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

Lighting & Textures

VanillaREPO Fidelity

VanillaREPO Fidelity

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

Object Detail

VanillaREPO Fidelity

VanillaREPO 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

• Aspect-ratio support - 21:9, 32:9, 16:10: world view fills the full screen instead of being squashed into a centered 16:9 box; wider panels lose the side letterbox. 4:3 and 5:4 fall back to vanilla letterbox, the HUD is a fixed 16:9 layout a
