Follow these steps in order. Each one is independent — skip any that don't apply to your setup.
In Marvel Rivals -> Settings -> Display -> Graphics, review Global Illumination. Lumen is Unreal Engine 5's real-time GI system and can be heavy on some GPUs, so test lower settings against your own visual-quality needs.
Open Settings -> Display -> Graphics Quality and test Low or Medium. Then selectively raise textures, effects, and post-processing until you find the best visibility and smoothness balance for your GPU.
In Display Settings -> Upscaling, test NVIDIA DLSS on supported RTX cards or AMD FSR on supported GPUs. Quality and Balanced modes can improve smoothness on many systems, but visual quality and latency tradeoffs vary.
Display Settings -> enable NVIDIA Reflex Low Latency if you have a supported NVIDIA GPU. It is intended to reduce render-queue latency in supported scenarios. AMD Anti-Lag is the comparable setting for supported AMD cards.
In Graphics, review Ray Tracing and Shadow Quality. Lower settings can reduce GPU load, especially in fast fights with many effects, but you should compare image clarity and performance on your own setup.
Display Settings -> Window Mode -> test Fullscreen and your preferred VSync behavior. VSync can add latency on some setups but may reduce tearing on others, so compare with your monitor and frame cap settings.
Review whether Balanced, High Performance, Ultimate Performance, or a custom profile makes sense for your PC. Power settings can affect CPU behavior during busy team fights, but laptops and desktops may need different choices.
For advanced gains, use SageTweaks for Unreal Engine 5-related Windows tuning, timer resolution, DPC latency reduction, GPU scheduling, and selected optimizations from the verified catalog with detected-game profile support.
Marvel Rivals runs on Unreal Engine 5 and can lean heavily on modern rendering features. Lowering Lumen/global illumination, shadows, effects, and upscaling settings can help some PCs. UE5 games can also stutter during shader compilation, so let the game finish first-run preparation before judging performance.
The right GPU depends on resolution, target refresh rate, upscaling mode, driver version, map, team fight intensity, and graphics settings. Start from the game publisher's current system requirements, then benchmark your own PC at your target resolution.
Frame Generation can improve visual smoothness but may add latency. For competitive play, compare Frame Generation against ordinary upscaling and native rendering to decide which tradeoff feels best on your setup.
Every optimization here operates at the Windows OS or in-game settings level. SageTweaks is designed for Windows-level optimizations and avoids game file modification, memory editing, and process injection, but anti-cheat policies can change, so review current game rules before applying any optimizer.
UE5 stutters are often related to shader compilation, traversal hitches, heavy effects, driver issues, or frame pacing. Try letting first-run shader work finish, lowering Lumen/global illumination, testing a frame cap, reviewing VBS/HVCI only if you understand the security tradeoff, and updating GPU drivers.
SageTweaks can organize selected Windows optimizations from 1,280+ verified tweak entries across 44 tweak catalogs, plus dedicated or detected-game profile support where available. Review changes before you apply them.
