Marvel Rivals stuck at 99% is a frustrating bug that has plagued many players trying to launch the game or load into matches. The loading screen hangs at the final percentage mark-99%-and never progresses, leaving users unable to play despite meeting system requirements. Whether you’re using an SSD, playing from a secondary drive, or struggling with network inconsistencies, this issue can be stubborn and unpredictable. Fortunately, a variety of community-sourced solutions can help you troubleshoot and potentially fix the problem.
If you’re asking yourself why is Marvel Rivals stuck at 99%, you’re not alone. While no single root cause has been officially confirmed by the developers, players and technical users have identified a few common threads. The most reported triggers include drive installation type, internet routing problems, and game file integrity-but even players with ideal setups have encountered the bug. That’s why this guide doesn’t promise a silver bullet but instead offers a broad toolkit of strategies.
What May Cause Marvel Rivals to Get Stuck at 99%?
Before diving into the solutions, it’s crucial to understand what might be happening behind the scenes. While the exact technical explanation remains unconfirmed, anecdotal and pattern-based evidence suggests several potential culprits. Keep in mind that the issue may stem from a combination of these rather than a single cause.
Game Installed on HDD or External Drive
A recurring observation is that users who install Marvel Rivals on traditional hard drives (HDDs) or external USB drives are more likely to encounter the 99% freeze. These storage methods have slower read/write speeds and can lead to bottlenecks during intensive loading phases. Moving the game to a fast internal SSD, especially on the C: drive, has helped many users-but not all.
“I was stuck for hours until I reinstalled on my internal SSD. That fixed it instantly. But a friend of mine is still stuck even after doing the same.”
This anecdote underscores the variability of the issue: SSD installation may significantly reduce the chances of hitting the bug, but it’s not guaranteed.
Faulty Internet Routing or High Latency
Some users report that the game hangs due to poor connectivity between their ISP and the Marvel Rivals servers. Even if your internet seems fast, it might not be stable or correctly routed. This problem is especially common for players in certain regions or using ISPs with inefficient paths to the game servers.
Many users found temporary relief by routing their connection through VPNs or third-party network tools. These methods often work by providing a more direct or stable route to the game’s infrastructure.
Corrupted or Missing Game Files
Another common issue arises from faulty or incomplete installations. When critical game files are missing, corrupted, or misconfigured, the loading screen may freeze at specific stages. Steam’s file verification tool can help identify and fix such discrepancies, and in some cases, a complete reinstall on a clean drive may be necessary.
Other Possible Causes
There are additional possibilities worth considering:
- Background processes interfering with game initialization
- Outdated or incompatible GPU drivers
- Anti-virus or firewall software blocking essential game components
- Incompatibility with overlays like Steam, Discord, or GeForce Experience
- Server-side bugs or match queue glitches
Some users even speculate that shader caching or texture streaming issues could contribute, especially on systems with limited VRAM or hybrid GPU setups (e.g., laptops switching between integrated and dedicated graphics).
How to Fix Marvel Rivals Stuck at 99%
Now that we’ve outlined the common causes, let’s walk through solutions that have worked for many in the community. The goal is to rule out each possibility methodically.
1. Move the Game to an Internal SSD
- Open Steam Library
- Right-click Marvel Rivals > Properties > Installed Files > Move Install Folder
- Choose a fast SSD (preferably internal, ideally the C: drive)
This step alone has resolved the issue for numerous users. However, it’s important to note that it is not universally effective. Even with SSDs, some users remain affected-so proceed to additional steps if the problem persists.
2. Verify Game Integrity
- In Steam, go to Marvel Rivals > Right-click > Properties
- Click on Installed Files > Select “Verify Integrity of Game Files”
- Allow Steam to scan and re-download any missing or broken files
This process ensures that your installation isn’t suffering from hidden corruption.
3. Run as Administrator
- Navigate to your Marvel Rivals executable file
- Right-click > Properties > Compatibility tab
- Check “Run this program as an administrator”
- Click Apply
Some game launch issues are tied to permission errors, especially on systems with tight User Account Control (UAC) settings.
4. Disable Overlays and Background Apps
Overlays and recording software can interfere with game loading. Disable or close:
- Steam overlay (Steam > Settings > In-Game > Uncheck “Enable Steam Overlay”)
- Discord overlay
- NVIDIA/AMD software overlays
- Third-party FPS counters or boosters
Also, close any non-essential background applications. Tools like MSI Afterburner, Razer Synapse, or RGB controllers may conflict with game processes.
5. Check Network Connection and Routing
- Use a wired Ethernet connection for stability
- Reboot your router or modem
- Temporarily disable any firewall or antivirus to test connectivity
- Change DNS to Cloudflare (1.1.1.1) or Google DNS (8.8.8.8)
- Consider using a VPN if you’re stuck-some users report that it bypasses poor routing paths
Optional Network Optimization Tools
Players dealing with persistent loading bugs related to connection quality sometimes try network optimization tools. Services like ExitLag, WTFast, and NoPing aim to reroute your traffic through optimized servers. While these tools are not officially endorsed by the developers and results vary by location, they have helped some players get past the loading bug.
Important: There is no independent confirmation that any one tool can universally fix this problem. Use these as experimental solutions rather than guaranteed fixes.
What ExitLag Can (and Can’t) Do
ExitLag is designed to:
- Reroute traffic through better-performing paths
- Lower ping and jitter
- Reduce packet loss in unstable regions
However, ExitLag:
- Does not fix corrupted game files
- Won’t help if the issue lies in local hardware or storage
- Might not affect anything if your connection is already stable
Use it if you’re seeing symptoms of poor routing or server mismatch, but don’t expect it to resolve all possible causes of the 99% bug.
Additional Troubleshooting Tips
- Reinstall the game on an SSD if file verification doesn’t help
- Update GPU and motherboard drivers through manufacturer websites
- Check Event Viewer in Windows for crash logs or blocked processes
- Allow Marvel Rivals through Firewall in Windows Defender and any third-party antivirus
- Restart your PC after applying each fix to ensure changes take effect
When All Else Fails
If you’ve tried everything and are still stuck:
- Uninstall Marvel Rivals completely
- Delete leftover files in %localappdata%, %appdata%, and Program Files
- Reinstall the game on your primary SSD
- Launch with no overlays and a clean boot setup
- Monitor game forums or support pages for hotfixes and patches
The Marvel Rivals dev team may address this issue in upcoming patches, so always keep your game up to date. In the meantime, troubleshooting thoroughly can increase your chances of a successful launch.
Advanced Fixes and Diagnostics
If you’ve exhausted basic fixes like SSD migration, verifying files, and disabling overlays, it’s time to try more advanced techniques that target edge-case issues.
1. Reinstall Visual C++ Redistributables
Although there’s no direct evidence linking Visual C++ packages to the 99% bug in Marvel Rivals specifically, some users have reported that reinstalling Windows runtimes resolved similar loading issues in other modern games.
- Visit Microsoft’s official website
- Download and install both x86 and x64 versions for 2013 and 2015–2022
- Reboot your PC afterward
This step is not guaranteed but can help eliminate conflicts tied to runtime dependencies.
2. Use Clean Boot Mode
Conflicts from third-party services can prevent Marvel Rivals from initializing properly.
- Open msconfig > Services tab > Check “Hide all Microsoft services” > Click “Disable all”
- Go to Startup tab > Open Task Manager > Disable all startup items
- Restart your system and try launching the game
This creates a minimal system environment, helping to isolate potential interference from background software.
3. Reset Network Settings
Some loading hangs may occur due to incomplete or failed server handshake processes. Resetting your network stack can help eliminate residual configuration errors that don’t appear in standard settings.
- Open Command Prompt (Admin)
- Run the following commands one at a time:
- netsh winsock reset
- netsh int ip reset
- ipconfig /flushdns
- Restart your PC
4. Check Game Log Files
Marvel Rivals may generate crash or debug logs in its installation folder or %appdata%.
- Look for files named output_log.txt, error.log, or crash.dmp
- If you find messages like “failed to load DLL” or “read/write error,” these likely indicate file corruption or permission issues
- Use this information to guide reinstallation, permissions fixes, or driver rollbacks
Not all users will find logs-or know how to read them-but scanning for basic error phrases can still offer guidance.
5. Test with a New Windows User Profile
Profile-specific bugs or permission restrictions may prevent full loading.
- Create a new local user account with admin privileges
- Reinstall Marvel Rivals under this profile and test loading behavior
This helps identify if the issue is tied to corrupted profile data or retained settings.
Community Reports: What’s Working?
While there’s no universal fix, many Reddit users and Steam forum members have reported varying degrees of success using the following:
- Installing on C:\SSD even if a game SSD already exists (Marvel Rivals seems to prefer primary disk)
- Using VPN temporarily to bypass regional issues with matchmaking or game state sync
- Removing USB peripherals (some obscure bugs stem from gamepad or USB controller conflicts)
- Waiting 5–7 minutes at the 99% screen – in rare cases, it eventually loads
Why This Bug Remains Unresolved
There’s growing consensus that the 99% bug in Marvel Rivals is caused by a combination of:
- Slow or delayed server authentication
- Local file access conflicts or permission blocks
- Inefficient error handling in the loading process
Because multiple weak links can trigger it, many users are affected inconsistently.
When to Contact Support
If you’ve tried everything listed in both parts of this guide and are still stuck:
- Collect your log files and system specs
- Note your install location, network provider, and any overlays used
- Contact NetEase or Marvel Rivals support through official channels
Although the developers have acknowledged the bug and stated they’re working on a fix, as of now, no documented patch fully resolves the 99% loading issue for all users. Providing detailed info may help the support team diagnose new variations.
Final Thoughts: A Layered Problem With Layered Fixes
The Marvel Rivals 99% loading bug is a perfect example of a layered technical issue. Some players fix it by simply switching drives; others need to rebuild their software environments entirely. While no fix is guaranteed, approaching the issue methodically increases your odds.
If you’re using any network optimization software, remember: these tools may assist with connectivity but won’t solve local file or system conflicts.
Lastly, keep your system updated and monitor community spaces like Reddit, Discord, and Steam forums for new hotfixes or developer statements.
Stay informed, stay patient, and may your next launch reach 100%.
