Fix: ERROR_GRAPHICS_CANT_RENDER_LOCKED_ALLOCATION (0xC0262111)

This error pops up when Windows can't render a video memory buffer that's locked. Usually it's a driver timeout or game bug. Here's how to squash it quickly.

This error is infuriating — I get it

You're in the middle of a game or a GPU-heavy app, and boom, the screen freezes or goes black, then you see the error: ERROR_GRAPHICS_CANT_RENDER_LOCKED_ALLOCATION (0xC0262111). The system says "A locked allocation cannot be used in the current command buffer." Sounds like gibberish, right? It's not your hardware dying. It's a driver timeout. Here's how to fix it in under 10 minutes.

The real fix: reset your graphics driver stack

Skip reinstalling Windows or buying a new GPU. This error almost always comes from a driver that got stuck waiting on the video memory. The quickest fix is a clean driver removal and reinstall. Not just a "repair" install — a full wipe.

  1. Download DDU (Display Driver Uninstaller) — head to Guru3D and grab the latest version. Do this in normal Windows, not Safe Mode yet.
  2. Boot into Safe Mode — press and hold Shift while clicking Restart. That gets you into the recovery menu. Go to Troubleshoot > Advanced Options > Startup Settings > Restart. Once the list pops up, press 4 or F4 for Safe Mode.
  3. Run DDU — open the tool. In the dropdown on the right, pick your GPU brand (NVIDIA, AMD, or Intel). Click "Clean and restart." Let it do its thing. Your screen will flicker a few times — that's normal. After it finishes, Windows will boot back normally without any graphics driver installed.
  4. Install the latest driver from your GPU maker's site — not from Windows Update. For NVIDIA, go to nvidia.com/drivers. For AMD, use amd.com/support. Download the full driver package, not the Express option — choose Custom Install and check "Clean Installation" if available.
  5. Reboot once more — after the driver installs, restart your PC. That's it. The error should be gone.

After you reboot, try launching whatever game or app was crashing. It'll likely work now. If it doesn't, move to the next section.

Why does this fix work?

The error code 0xC0262111 translates to a specific Windows graphics kernel behavior. The GPU's video memory (VRAM) has allocations — think of them as chunks of memory the GPU uses to render frames. Sometimes a chunk gets "locked" by the driver for a write operation, but then the next command buffer (the list of rendering instructions) tries to use that same chunk. The Windows Display Driver Model (WDDM) sees this as a conflict and throws the error.

This usually happens because an older, corrupted driver cache leaves stale memory locks behind. When you install a new driver on top, those locks might persist. DDU strips out every trace — registry keys, driver store files, everything. A clean driver install then starts fresh, with no lingering locked allocations.

I've seen this error on Windows 10 and 11 machines with both NVIDIA and AMD cards. It's not brand-specific. The trigger is almost always a driver that crashed during a previous session (maybe a game crashed, or Windows did a fast startup that left GPU state hanging).

Less common variations of the same issue

Sometimes the DDU method isn't enough. Here are three other scenarios and their fixes:

1. TDR timeout is too short

Windows has a built-in watchdog called TDR (Timeout, Detection, and Recovery). If the GPU takes more than 2 seconds to respond to a command, Windows assumes it's frozen and resets it. That reset can trigger 0xC0262111. You can extend the timeout:

  • Press Win + R, type regedit, hit Enter.
  • Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers.
  • Right-click on the right pane, choose New > DWORD (32-bit) Value. Name it TdrDelay.
  • Set the value to 8 (that's 8 seconds, decimal).
  • Also create a second DWORD named TdrDdiDelay with value 8.
  • Close regedit and restart your PC.

This won't fix the root cause, but it gives your GPU more breathing room so a slow frame doesn't trigger the error.

2. Overclocking instability

If you've overclocked your GPU or RAM, dial it back to stock speeds. I've seen this error pop up on cards that were stable for months but then started failing after a Windows update changed the power management timing. Use MSI Afterburner or your GPU's own tool to reset core clock, memory clock, and voltage to default. Test for 30 minutes. If the error stops, you found your culprit.

3. Corrupted Windows graphics stack

Rare, but possible. Run DISM and SFC from an admin command prompt. Open Command Prompt as admin, then: DISM /Online /Cleanup-Image /RestoreHealth and press Enter. After that finishes, run sfc /scannow. Reboot. This fixes corrupted system files that manage the graphics subsystem.

Prevention — keep this from coming back

Once you've fixed it, do these three things:

  • Always do a clean driver install — when you update your GPU driver, use the Custom Install option and check "Clean Installation." Don't let the installer keep old files.
  • Disable fast startup in Windows — that hybrid shutdown feature can leave GPU memory states locked. Go to Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable > uncheck "Turn on fast startup." Save changes.
  • Don't run GPU-intensive apps right after boot — give Windows 30 seconds to settle before launching a game. Sounds silly, but I've seen this error happen when the driver hasn't fully initialized.

That's it. The error 0xC0262111 is annoying but not dangerous. A clean driver install and a registry tweak for TDR will get you back to gaming without the headache.
