3dmark Stuck On Starting Ui Instant

The Infinite Loading Screen: Why 3DMark Gets Stuck on "Starting UI" and How to Fix It For PC enthusiasts, overclockers, and hardware reviewers, 3DMark is the gold standard for benchmarking. It is the arena where silicon battles are fought. But before you can watch your graphics card flex its muscles, you have to get past the lobby. Lately, a silent killer of benchmarking sessions has emerged: the dreaded "Starting UI" loop. You click the icon. The splash screen appears. The progress bar twitches... and then nothing. The application hangs, sometimes for hours, sometimes indefinitely. You are not alone. This feature breaks down exactly why this happens and provides a surgical strike guide to getting back to benchmarking. Part 1: The Anatomy of the Glitch Unlike a crash that produces an error code, the "Starting UI" freeze is a soft lock . The process is running in Task Manager, consuming minimal CPU and RAM, but the graphical user interface refuses to materialize. What is actually happening? When 3DMark launches, it performs a handshake with its backend servers (owned by UL Solutions). It checks for:

User authentication (Steam or standalone license). DLC validation (Time Spy, Port Royal, Speed Way). Hardware database updates. System information (SysInfo) module compilation.

If any of these steps stall—specifically the SysInfo module or a web request —the UI logic waits forever. It does not time out. It does not error. It simply waits . Part 2: The Usual Suspects Through analyzing thousands of forum threads (Guru3D, Reddit, UL’s official community), three primary causes emerge: 1. The SysInfo Compilation Hell (80% of cases) 3DMark uses a low-level system information gatherer. On first launch (or after a Windows update), it must compile a kernel driver on-the-fly. Antivirus software (McAfee, Norton, even Windows Defender) often quarantines this compilation step because it looks like a rootkit installer. 2. The Network Timeout Loop The 3DMark client tries to fetch news banners, your Steam friends' scores, and the Hall of Fame leaderboards before rendering the UI. If you have a strict firewall, a VPN, or IPv6 misconfiguration, the HTTP request hangs. The UI waits for the network response that never comes. 3. Corrupted Local Storage Cache 3DMark saves your results and hardware profiles locally. If that database file gets corrupted (usually after a blue screen or forced shutdown), the application tries to read it, fails silently, and hangs on "Starting UI." Part 3: The Fixes (From Gentle to Nuclear) Do not reinstall Windows. Do not return your GPU. Follow this hierarchy of fixes. Level 1: The 5-Second Fix (Network Isolation) Before doing anything else, disconnect your internet. Unplug the Ethernet cable or turn off Wi-Fi. Then launch 3DMark.

If it works: Congratulations. Your firewall or ISP is blocking UL’s telemetry. Once the UI loads, you can plug the internet back in. To fix permanently, add 3dmark.exe and ul_futuremark_sysinfo.exe to your antivirus whitelist. If it doesn’t work: Move to Level 2. 3dmark stuck on starting ui

Level 2: The Steam Integrity Gambit (Steam users only) Corrupted manifests are common.

Right-click 3DMark in Steam > Properties . Click Installed Files . Click Verify integrity of game files . Wait for it to reacquire 2-3 files. Launch again.

Level 3: The Nuclear SysInfo Reset (The most effective) This targets the 80% cause. The Infinite Loading Screen: Why 3DMark Gets Stuck

Close 3DMark completely (check Task Manager). Navigate to: C:\Program Files (x86)\Steam\steamapps\common\3DMark\bin\x64 (or your custom install folder). Find the folder named SysInfo . Delete the entire SysInfo folder. Launch 3DMark. It will rebuild the SysInfo module from scratch, forcing a clean compilation. Your antivirus will likely pop up— allow it .

Level 4: The Config Purge (UI settings) If SysInfo isn't the issue, the UI config is.

Press Win + R , type %localappdata% , press Enter. Find the folder named UL_3DMark . Inside, delete config.bin and the cache folder. Restart 3DMark. Lately, a silent killer of benchmarking sessions has

Level 5: The Driver Dance (AMD/Intel specific) On systems with integrated graphics (laptops) or recent AMD GPUs, 3DMark gets confused about which GPU handles the UI rendering.

For laptops: Force 3DMark to run on the dedicated GPU via Windows Graphics Settings (High Performance). For AMD: Roll back to driver version 23.11.1 or newer. The 24.x series had a specific OpenGL UI hang.
