Marvel Rivals Best Settings & FPS Boost Guide

Marvel Rivals runs on Unreal Engine 5, and UE5's headline feature — Lumen Global Illumination — is also its biggest performance hog. Left at defaults, Marvel Rivals can run hot and slow on mid-range hardware that should easily hit high refresh rates.
The good news: a handful of targeted settings recover up to 30% FPS with nearly identical competitive visuals. This guide gives you the exact settings to use, breaks down the FPS-boosting toggle, and includes a complete settings table for low, mid, and high-end PCs.
The #1 FPS Fix: Disable Lumen Global Illumination
Lumen computes real-time global lighting, and it does so at a serious performance cost with UE5. In Marvel Rivals, this is the single largest frame-rate lever:
- Default: Lumen GI running in real-time — expensive on GPU and CPU.
- Fix: Set global illumination to SSGI Low (or Shaided settings as low as possible).
Switching from Lumen to SSGI Low Quality alone recovers roughly 24–30% FPS with negligible visual impact in most team-fight scenarios. This is the # try the toggle to start with.
Competitive Settings That Give You an Advantage
Beyond raw frames, you want low latency and high visibility for ranked play. Set these:
- Display Mode: Exclusive Fullscreen (stops Windows compositor overhead)
- Vertical Sync: Disabled (adds input lag)
- NVIDIA Reflex: Enabled On + Boost (or AMD Anti-Lag) — reduces system latency
- Frame Generation: OFF for ranked/competitive — it adds 10–20ms of input latency you don't want when you're aiming
The Frame Generation Question
- Frame Generation (DLSS FG / FSR 3 FG) multiplies display rate on the frame, but adds input latency. Optional for single-player, not recommended for competitive.
- Reflex On + Boost reduces render latency and is effectively free.
Marvel Rivals Settings Table (Low / Mid / High)
| Setting | Low-End PC | Mid-End PC | High-End PC | |---|---|---|---| | Display Mode | Fullscreen | Fullscreen | Fullscreen | | Resolution | 1080p/1280× | 1440p | 1440p/4K | | Global Illumination | SSGI Low | SSGI Low | SSGI Med/Lumen | | Shadows | Low | Low–Med | Medium | | Effects / Post | Low | Medium | High | | Model Detail | Low | Medium | High | | DLSS/FSR | Off/Per Quality | On Quality | On Quality | | Reflex/Anti-Lag | On+Boost | On+Boost | On+B | | Frame Gen | Off | Off | Off (competitive) |

The Built-in CPU Performance Toggle — What's for
NetEase slipped an experimental CPU rendering optimization into Marvel Rivals: Settings → Other → Enable In-Game Performance Optimization.
It requires accepting an opt-in privacy prompt, downloads a rendering patch, and forces a restart. On higher-end CPUs it can pegsus some off-loading gains; on lower-end machines it sometimes causes erratic stutter. If performance does not improve after it restarts, turn it off.
Background Process Cleanup (The Easy Frames)
Marvel Rivals benefits from a clean Windows backing. There are three near-free steps to get easy frames: close Chrome/Discord hardware acceleration, disable in-game overlays, and put the PC on the High Performance power plan. For a complete rundown, see our best Windows gaming settings guide.
The Full-Automation Chestcode
Rather than juggling settings across low / mid / high and re-tuning every update, SageTweaks can apply the Windows half of the battle plan — the power plan, background process trimming, and system latency settings — in one click. Time you spend tweaking is time not spent playing.
Bottom line: Flip Lumen off (SSGI Low), Prefer Reflex On + Boost, set Power Plan High Performance — you just recovered 24–30%+ FPS in Marvel Rivals. Applying these settings is the difference between a choppy hero shooter and a smooth, competitive one.
