Marvel Rivals Windows Optimizations: 14 Reversible Tweaks
Windows Optimizations is a tab in RIVALSFPS.GG with 14 Windows settings that sit outside Marvel Rivals, in five groups: network, system, GPU, power and input. Each one is applied on its own, the ones that need a restart are marked, and each comes off again with Revert.
None of them touches the game's files or its graphics settings. They change how Windows treats your network adapters, power plan, graphics card choice, display and input while you play. No FPS, ping or latency figure is published for any of them, so treat each one as a setting to check rather than a promised gain. The window below shows the tab with one tweak applied.
Two to check first
Most of the list is about how Windows behaves in the background. Two rows are different: each one fixes a PC that is set up wrong, so check them before the rest.
Max Refresh Rate
Windows does not always run a monitor at its highest refresh rate, so a 144Hz or 240Hz panel can sit at 60Hz without you noticing. This row sets the top rate your display offers at its current resolution.
Prefer High-Performance GPU
A laptop with integrated and dedicated graphics can run the game on the integrated chip. If the game runs far worse than your hardware should allow, check this row first.
Which tweaks need a restart or a Windows prompt
A Requires Restart chip means Windows only reads the new value after a reboot; the app reminds you once per session after you apply one. The prompt column marks the system-wide tweaks. Applying or reverting them usually raises a Windows permission (UAC) prompt, and the app shows a short notice before it does.
| Tweak | Group | Requires Restart | Windows prompt |
|---|---|---|---|
| TCPNoDelay | Network | Yes | Usually |
| Network Throttling Off | Network | Yes | Usually |
| Update Seeding Off | Network | No | Usually |
| Network Adapter Full Power | Network | No | Usually |
| Windows Game Mode On | System | No | No |
| Background Recording Off | System | Yes | No |
| Hardware GPU Scheduling | GPU | Yes | Usually |
| Prefer High-Performance GPU | GPU | No | No |
| Max Refresh Rate | GPU | No | No |
| Ultimate Performance Plan | Power | No | Usually |
| Power Throttling Off | Power | Yes | Usually |
| Mouse Acceleration Off | Input | No | No |
| Accessibility Popups Off | Input | No | No |
| Xbox Button Popup Off | Input | No | No |
What each tweak changes
Each entry says what the tweak does, then where it writes in Windows, taken from the app's own catalog.
Network
- TCPNoDelay Turns off Nagle's algorithm, which holds small packets back so it can send them together, and turns off delayed acknowledgments as well. The app sets both on every network interface that has an IP address. Where: TCPNoDelay and TcpAckFrequency under HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces. Revert deletes both values again.
- Network Throttling Off Removes the cap that Windows' multimedia scheduler (MMCSS) places on network traffic. Where: NetworkThrottlingIndex under HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile.
- Update Seeding Off Stops Delivery Optimization trading Windows Update pieces with other PCs, in both directions. Updates still download straight from Microsoft. If your organization manages this setting, the row reads "Managed by your organization's policy." and cannot be applied. Where: The DownloadMode value behind Windows' Delivery Optimization setting.
- Network Adapter Full Power Stops Windows switching your network adapters off to save power, and sets the power plan's wireless adapter setting to Maximum Performance. If an adapter's driver does not support the change, the app skips it and tells you. Where: The power management option Device Manager shows for each adapter, plus the power plan's wireless adapter setting.
System
- Windows Game Mode On Switches on Windows Game Mode. Windows ships with it on, so this row can already show Applied. Where: AutoGameModeEnabled under HKCU\Software\Microsoft\GameBar.
- Background Recording Off Turns off Windows' background game capture, which keeps a rolling recording of recent gameplay and uses the GPU's video encoder to do it. Where: GameDVR_Enabled under HKCU\System\GameConfigStore and AppCaptureEnabled under HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\GameDVR.
GPU
- Hardware GPU Scheduling Turns on hardware-accelerated GPU scheduling, so the graphics card manages its own queue of work. It depends on a card and driver that support it. Where: HwSchMode under HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers. Revert deletes the value, which leaves the choice to the driver.
- Prefer High-Performance GPU Sets the per-app graphics preference for Marvel-Win64-Shipping.exe to your high-performance GPU, the same preference Windows Settings keeps for each app. The row needs your game folder located in the app first. Where: The game exe's entry under HKCU\Software\Microsoft\DirectX\UserGpuPreferences. Other preferences in that entry are left as they were.
- Max Refresh Rate Switches your main display to the highest refresh rate it offers at your current resolution. It refuses while Stretched Resolution is on, because changing the rate then would make the 4:3 desktop permanent. Where: The display mode itself, not the registry.
Power
- Ultimate Performance Plan Makes a copy of Windows' hidden Ultimate Performance power plan and selects it. PCs that use Modern Standby cannot run that plan, and there the row reads "Not available on this PC (Modern Standby)." Where: Windows power plans, through powercfg. Revert selects Balanced and deletes the copy.
- Power Throttling Off Turns off Power Throttling, the Windows feature that slows background apps down to save energy, so apps such as Discord or capture software run at full speed. On a laptop it costs battery. Where: PowerThrottlingOff under HKLM\SYSTEM\CurrentControlSet\Control\Power\PowerThrottling.
Input
- Mouse Acceleration Off Turns off Enhance Pointer Precision, so the cursor moves the same distance for the same mouse movement at any speed. It takes effect right away. Where: MouseSpeed, MouseThreshold1 and MouseThreshold2 under HKCU\Control Panel\Mouse.
- Accessibility Popups Off Turns off the keyboard shortcuts that pop up the Sticky Keys, Filter Keys and Toggle Keys prompts. A feature you have switched on is skipped and keeps working. Where: The StickyKeys, Keyboard Response and ToggleKeys keys under HKCU\Control Panel\Accessibility. Only the shortcut flag changes.
- Xbox Button Popup Off Stops the Xbox button on a controller opening the Game Bar. Win+G still opens it, and capture still works. Where: UseNexusForGameBarEnabled under HKCU\Software\Microsoft\GameBar.
The 14 tweaks above are on the Windows Optimizations tab of RIVALSFPS.GG, a free Windows app. Apply the ones you want; Revert All undoes the set.
Free for Windows 10 and 11.
Download for WindowsReverting
Before a tweak first changes anything, the app records what was there, including when a setting did not exist at all. How Revert uses that record depends on the kind of tweak. The seven tweaks without a Windows prompt put back the recorded value. The seven system-wide tweaks restore the Windows default, which is what the app's footnote means by "Revert restores the Windows default." Two of those work a little differently: Network Adapter Full Power puts back each adapter's recorded setting, and Ultimate Performance Plan selects Balanced and deletes its copy of the plan.
Revert All undoes every applied tweak, with a single Windows prompt for all the system-wide ones. Apply and Revert both refuse while Marvel Rivals is running and ask you to close the game first. Revert All Changes, in Settings under Diagnostics, also takes the Windows optimizations off along with everything else the app changed, and the uninstaller's "Also undo every change made to Marvel Rivals" option covers Windows tweaks too.
What this will not fix
These settings change Windows, not the game's render load. If your problem is stutter rather than input feel, start with the Marvel Rivals stuttering fix. If you want each frame to cost less, the changes are in the game's menu and in the app's other tabs: read how to increase FPS in Marvel Rivals and the best settings for a low-end PC. In the app, the Quality tab has Lower Render Resolution on any graphics card and Quality presets for NVIDIA cards only.
Common questions
Do Windows optimizations increase FPS in Marvel Rivals?
No FPS figure is published for any of the 14. Two of them matter when a PC is set up wrong: Max Refresh Rate, if the monitor runs below its top rate, and Prefer High-Performance GPU, if a laptop runs the game on its integrated graphics. The rest change how Windows handles networking, power, background recording and input.
Can I undo the Windows optimizations?
Yes. Each tweak has its own Revert, and Revert All undoes every applied tweak at once. The seven tweaks without a Windows prompt put back the value the app recorded before its first change. The seven system-wide tweaks restore the Windows default, except Network Adapter Full Power, which puts back each adapter's recorded setting.
Do I need to restart after applying them?
Five of them need a restart before Windows uses the new value: TCPNoDelay, Network Throttling Off, Background Recording Off, Hardware GPU Scheduling and Power Throttling Off. Their rows carry a Requires Restart chip.
Which tweaks ask for Windows permission?
The seven system-wide ones usually raise a Windows permission (UAC) prompt: TCPNoDelay, Network Throttling Off, Update Seeding Off, Network Adapter Full Power, Hardware GPU Scheduling, Ultimate Performance Plan and Power Throttling Off. Before the prompt, the app shows a short notice saying Windows will ask.
Can I apply just one?
Yes. Every row has its own Apply and Revert, and nothing is bundled.
