Common causes & fixes
Outdated GPU drivers
Paralives uses Unity with DirectX 11. NVIDIA and AMD shipped Paralives-day-0 game-ready drivers; older drivers cause black screens on startup. Update from the official vendor (not Windows Update).
Source ↗Steam / Discord / GeForce overlay conflicts
Overlay injectors (Steam, Discord, MSI Afterburner, RTSS, Nvidia ShadowPlay) can prevent the first frame from rendering. Disable Steam Overlay for Paralives in Properties → General, and quit Discord before launching.
Source ↗Corrupted install / interrupted download
Verify integrity of game files in Steam. ~3-5% of day-0 installs hit a partial download because of Steam load.
Source ↗Antivirus quarantining UnityPlayer.dll
Windows Defender, Bitdefender, Norton occasionally flag UnityPlayer.dll as a heuristic false positive. Whitelist the Paralives install folder (Steam\steamapps\common\Paralives).
Source ↗Wrong GPU selected on laptops
Hybrid GPU laptops sometimes default to the integrated chip. Right-click the desktop → NVIDIA Control Panel → Manage 3D Settings → add Paralives.exe → set to High-performance NVIDIA processor.
Source ↗Sub-spec hardware
Minimum is 12 GB RAM, DX11 GPU at ~GTX 1060 / RX 6600 XT class. Lower than that and the game may load to a black screen and exit silently.
Source ↗Missing Visual C++ / .NET redistributables
Steam normally installs these on first launch, but failures happen. Reinstall the latest VC++ x64 redistributable from Microsoft.
Source ↗Audio device disconnected on startup
There's a known day-0 bug where the game can hang on a black screen if the default audio output disappears (Bluetooth headphones disconnecting mid-launch). Set a wired output as default and relaunch.
Source ↗Verify game files in Steam
Corrupted installs are the #2 cause of launch failure after driver issues. Steam can re-check every file and re-download anything broken.
- 1 Open Steam
Click Library, right-click Paralives.
- 2 Open Properties
Bottom of the right-click menu.
- 3 Installed Files tab
Then click "Verify integrity of game files".
- 4 Wait for completion
Steam will redownload any corrupted file. Takes 1-3 minutes on SSD.
- 5 Relaunch
If files were repaired, restart Steam fully before launching again.
Steam launch options
Right-click Paralives in your Library → Properties → General → "Launch Options". Paste one of these flags:
-force-d3d11- Force DirectX 11. Default on Windows, useful if a previous run left a stale D3D12 state.
-screen-fullscreen 0- Force windowed mode. Bypasses display-mode handshake issues on multi-monitor setups.
-screen-width 1280 -screen-height 720- Force a low safe resolution if a previous session saved an invalid one.
-logFile output.log- Write the Unity engine log next to the exe — paste it on Discord when asking for help.
