Fix Marvel Rivals FPS Drops and Packet Loss on PC

Quick answer: Treat low FPS and packet loss as two different problems. For FPS drops, assign Marvel Rivals to the high-performance GPU in Windows, update the graphics driver, and lower the heaviest graphics options. For packet loss, check game-service status, test a wired connection, and troubleshoot the local network.

Before you start

• Install current Marvel Rivals updates.
• Restart the PC once and close overlays or downloads you do not need.
• Watch the in-game indicators: uneven animation with stable latency suggests FPS trouble; rubber-banding or delayed actions with packet-loss warnings suggests a network problem.

Fix FPS drops on Windows

1. Open Settings > System > Display > Graphics.
2. Add or select the Marvel Rivals executable. If it is not listed, choose the desktop-app option, browse to the game folder, and select Marvel.exe.
3. Open Options, choose High performance, and save. This step is also documented in the official Marvel Rivals launch FAQ.
4. Install the latest stable graphics driver from NVIDIA, AMD, or Intel, then restart Windows.
5. In Marvel Rivals, reduce shadows, effects, reflections, and render resolution one setting at a time. Keep the frame-rate cap at a value the PC can hold consistently.
6. If available in your current client, run the official in-game performance optimization/test tool under Settings > Other and review its recommendations.

Fix packet loss

1. Check Marvel Rivals announcements and platform service status for maintenance.
2. Pause cloud sync, streaming, or large downloads on the same network.
3. Test with Ethernet. If the loss disappears, improve Wi-Fi signal, use the 5 GHz or 6 GHz band at short range, or move closer to the router.
4. Restart the modem/router and PC. Do not factory-reset the router.
5. Compare another online game or a continuous network test. If multiple services lose packets, contact the ISP with the test time and result.

Why these fixes work

The Windows graphics preference prevents a laptop or multi-GPU PC from choosing a slower adapter. Driver and graphics changes reduce rendering workload and frame-time spikes. Packet loss occurs outside the rendering pipeline, so it needs a network path fix; lowering graphics settings cannot repair dropped network packets.

What the source video leaves out

The video shows a Steam launch-options field but does not narrate or clearly reproduce the exact command. This guide intentionally does not copy that unknown command. Unverified launch flags can reduce stability or stop the game from starting. The video also groups FPS drops and packet loss together; this guide separates them because they have different causes.

Warnings and undo

Changing the Windows GPU preference is reversible: return to Graphics settings and choose Let Windows decide. Reset in-game graphics to defaults if visual quality or stability worsens. Avoid registry cleaners, “FPS boost” executables, and disabling Windows security.

FAQ

Can high ping cause low FPS?

It can make actions feel delayed, but it normally does not lower the rate at which the GPU draws frames. Measure both separately.

Should I use every Steam launch option I find?

No. Use only documented options you can identify and undo. The source video does not provide enough information to verify its field.

Is High performance always the best choice?

It is appropriate while plugged in for gaming, but it can increase power use and heat on a laptop.
