STATUS_GRAPHICS_UNSWIZZLING_APERTURE_UNAVAILABLE Fix

1. Too Many Apps Hogging Apertures

The culprit here is almost always running multiple GPU-heavy apps at once. Unswizzling apertures are limited slots the GPU uses to handle texture data — think of them as parking spaces. When they're full, you get 0xC01E0107.

I've seen this most often when someone's got a game, a video renderer, and Chrome with hardware acceleration all fighting for the same apertures. On a system with 16GB RAM and a GTX 1080, three such apps can max it out.

What to do:

1. Open Task Manager (Ctrl+Shift+Esc). Go to the Performance tab, look at GPU usage. If it's pegged at 100%, that's your bottleneck.
2. Close anything you don't need: web browsers, Discord overlay, streaming software, game launchers in the background.
3. If you're in a game, drop the graphics settings — especially texture quality and anti-aliasing. Those eat aperture slots.
4. Reboot. A fresh start clears the aperture table. If the error comes back immediately after reopening one app, skip to cause #2.

2. Corrupt or Leaky GPU Driver

If closing apps doesn't help, the driver's probably leaking memory or aperture handles. This is classic with NVIDIA's Game Ready drivers on certain versions — I've fixed it on driver 536.67 and later on 546.17. AMD's Adrenalin drivers had a similar issue in 2023 versions.

The fix is a clean driver install. Don't bother with the "Express Install" — it leaves old files behind.

How to nuke it properly:

1. Download Display Driver Uninstaller (DDU) from the official site. Get the latest version.
2. Boot Windows into Safe Mode. Press Shift while clicking Restart, then Troubleshoot > Advanced Options > Startup Settings > Restart, then press 4 for Safe Mode.
3. Run DDU. Select your GPU vendor (NVIDIA or AMD). Click "Clean and restart (recommended)".
4. Once rebooted, Windows will install a basic driver. Download the latest driver from NVIDIA or AMD — but skip the "GeForce Experience" or "Adrenalin" companion apps. They're bloat.
5. Install the driver manually. Choose "Custom (Advanced)" and check "Perform a clean installation".
6. Reboot again. Test your app.

If the error persists, try rolling back to a driver from 3-6 months ago. Sometimes the newest drivers break things.

3. GPU Overlays and Third-Party Apps

Overlays are notorious for eating apertures. Discord, NVIDIA GeForce Experience, MSI Afterburner, RivaTuner — they all inject into the graphics pipeline and grab aperture slots.

I had a user last week with an RTX 4070 and 32GB RAM, couldn't run Unreal Engine 5 without hitting 0xC01E0107. Turned off Discord's overlay and the error vanished.

Disable overlays:

• Discord: User Settings > Game Overlay > Toggle off "Enable in-game overlay".
• NVIDIA GeForce Experience: Settings > General > Toggle off "In-Game Overlay".
• MSI Afterburner / RivaTuner: Uninstall them. They're not needed unless you're overclocking.
• Xbox Game Bar: Settings > Gaming > Game Bar > Turn off.

Also check for any app that shows FPS or captures video — those are prime suspects.

Quick-Reference Summary

If none of these work, you might be looking at a hardware issue — failing GPU or faulty VRAM. Run a tool like FurMark to stress test the card. But 90% of the time, it's one of the three above.
