Walls Disappearing?

If you are playing the demo and the walls start disappearing, this is likely a known bug with GZDoom and we're doing everything on our power to fix it. In the meantime there are several workarounds you can try. We apologize for any inconvenience this may cause you. We strive to provide the highest-possible quality experience possible, and we know that this bug can render your game unplayable. Thanks for your patience and support!

If you have an NVIDIA graphics card:

• Press Esc to return to the main menu. Select Options.
• If the menu is not accessible, move into an area where the bug is not present and attempt to open the menu again.
• From the options menu select Graphics Options.
• From the Graphics Options menu, select Preferred Rendering API and choose OpenGL.
• Close out of your game and return to desktop. Once the application is closed, relaunch the game.
• Return to the Graphics Options menu to confirm the game is now set to OpenGL.

If the problem persists, please let us know immediately.

If you have an AMD graphics card:

• Press Esc to return to the main menu. Select Options.
• If the menu is not accessible, move into an area where the bug is not present and attempt to open the menu again.
• From the options menu select Graphics Options.
• From the Graphics Options menu, select Preferred Rendering API and choose GLES.
• Close out of your game and return to desktop. Once the application is closed, relaunch the game.
• Return to the Graphics Options menu to confirm the game is now set to GLES.

If the problem persists, please let us know immediately

If you are using an AMD graphics card, if your drivers are newer than Radeon 20.12.1 we recommend that you use the GLES renderer. If your drivers are 20.12.1 or lower, we recommend using the OpenGL renderer.

For the best possible experience on AMD cards, install Radeon 20.12.1 drivers. AMD's latest updates broke the OpenGL renderer and we are powerless to resolve this issue without direct support from AMD.
