Understanding OBS Black Screen Issues
OBS Game Capture black screens occur when the software cannot properly hook into the game's rendering process. Common causes include:
- Anti-cheat interference: Vanguard (Valorant) and VAC (CS2) blocking OBS hooks
- Graphics driver conflicts: Outdated or incompatible GPU drivers
- Game running as administrator: Permission mismatches between OBS and games
- Fullscreen optimizations: Windows display settings interfering with capture
- Hardware acceleration issues: Conflicts between OBS and GPU acceleration
Both CS2 and Valorant use robust anti-cheat systems that can interfere with screen capture software, making these games particularly challenging to stream.

Frequently Asked Questions
Why does Game Capture work sometimes but not others?
This usually indicates anti-cheat interference or permission conflicts. Try running OBS as administrator consistently and ensure games aren't running in exclusive fullscreen mode.
Does using Window Capture affect stream quality?
Window Capture can be slightly less efficient than Game Capture but quality difference is minimal. It's often more reliable for games with aggressive anti-cheat systems.
Can I stream CS2 and Valorant simultaneously?
No, both games use kernel-level anti-cheat that prevents running simultaneously. You'll need to close one game before launching the other.
Why does my OBS show black screen only in fullscreen games?
Fullscreen exclusive mode can block OBS hooks. Switch to borderless windowed mode or disable Windows fullscreen optimizations for the game.
Is it safe to disable Vanguard to fix OBS issues?
You cannot disable Vanguard while playing Valorant - it's required. Instead, use the workaround of restarting Vanguard after starting OBS, or use alternative capture methods.
Should I use GPU or CPU encoding while streaming these games?
Use GPU encoding (NVENC/AMD VCE) if available - it reduces CPU load, allowing better game performance. CPU encoding provides slightly better quality at higher bitrates.
Why does Display Capture work but Game Capture doesn't?
Display Capture bypasses game hooks entirely, while Game Capture requires direct access to the game's rendering. Anti-cheat software often blocks the latter but not the former.
Can outdated Windows versions cause OBS black screen?
Yes, Windows 10 version 1903+ or Windows 11 are recommended for best OBS compatibility. Older versions may have DirectX or graphics API conflicts.
How do I know if my graphics driver is causing the issue?
Try using Display Capture instead of Game Capture. If Display Capture works fine, the issue is likely driver-related or game-specific rather than a general system problem.
What's the difference between Game Capture modes in OBS?
"Capture any fullscreen application" automatically detects games but is less reliable. "Capture specific window" targets a particular game window and works better with modern anti-cheat systems.
💡 Pro Tip
Create multiple scenes in OBS: one with Game Capture for when it works, and another with Window/Display Capture as backup. This allows quick switching during stream without interruption.
