What's New in RIVALSFPS.GG 5.3.0

RIVALSFPS.GG 5.3.0 came out on October 14, 2026. Voice mods that stopped working after recent game updates play again, the app checks for the Unmount Blocker plugin and offers to remove it before you launch, and Stretched Resolution adds 16:10 options with no black bars and a normal HUD.

The app checks for updates by itself and, by default, installs this one the next time it starts. If you chose Ask before updating in Settings, it shows Update available and Restart & Update installs it. The What's New bell in the titlebar lists the same changes, each with a button that opens the tab it is about.

Remove the Unmount Blocker

The Unmount Blocker is a plugin that patches the running game so it keeps old-style .pak mods open, and players running it have been reporting warnings and bans. RIVALSFPS.GG does not need it. 5.3.0 looks for it when the app starts, under any file name, and asks "Remove the Unmount Blocker?". If it is still there when you press Launch, the app asks again, and Remove and launch takes it out and starts the game in one click. The file is moved to a quarantine folder, not deleted. What it does and how to remove it by hand is in the Unmount Blocker and the ban reports.

Voice mods play again

Since a September 2026 update the game closes plain .pak mods shortly after it starts, before a hero's voice lines load, so ult line and other voice mods went quiet. In the Mod Manager, sound mods now have their own Sound Mods section, and any that stopped playing are marked Outdated. Fix, or Tools, then Fix Mods for Game Update, converts each one so its lines play from sound files the game loads at startup. The original is backed up first, and Restore original puts it back.

Each sound mod has its own switch and several play together. When two change the same sound, the one listed first plays and the other gets a Conflict badge naming it. Sound mods you built in the Sounds tab are listed there too, and the gear on their row opens them in the Sounds tab to edit. The badges, and the few kinds of mod Fix cannot convert yet, are covered in Marvel Rivals voice mods not working.

Stretched Resolution at 16:10

Stretched Resolution, in Settings under Display, has four new Wide (16:10) resolutions: 1920x1200, 1680x1050, 1440x900 and 1280x800. Marvel Rivals fills a 16:10 frame by itself, so these stretch about 11% wider on a 16:9 monitor with no black bars, a normal HUD and nothing installed. The Classic (4:3) resolutions are still there for the widest look, with their black bars choice.

Two reliability changes came with it. If the game switches to Fullscreen and the stretch drops, it comes back by itself once the game is back in Borderless. And your display and the game's settings are now put back only after the game has closed. The setup and the trade-offs are in stretched resolution with no black bars.

Where to go next

If you are new to the app, how to install Marvel Rivals mods covers the Mod Manager, and Marvel Rivals sound mods covers building your own hit, kill and announcer sounds in the Sounds tab. For the graphics side, the Max FPS preset covers the layers that 5.2.0 added.

The button on the download page fetches the current release from GitHub, and by default the app keeps itself up to date after that.
