Failed to lock index buffer in CMeshDX8::LockIndexBuffer

Failed to lock index buffer in CMeshDX8::LockIndexBuffer
Question

The game crashes and I get the error: 'Failed to lock index buffer in CMeshDX8::LockIndexBuffer'
Answer
Paged Pool Memory

The direct cause of this error is not having enough paged pool memory free for the game engine.

Please see the Games freeze or crash with looping sounds (paged pool memory issues) topic for more information.


Do Not Alt-Tab While In-game

The 'Failed to lock index buffer' error may also occur when you Alt+Tab to switch between windows while playing a game and your machine is unable to allocate sufficient memory to render graphics when you switch back to your game window.

The best solution for this behavior is to properly exit the game to return to your desktop so you may work with other applications.

This issue may also be related to an outdated driver for your video card. To address this issue, it is recommended that you uninstall your current Catalyst drivers, then install the latest drivers.
