Verify the Integrity of Apex Legends Files
Close your file explorer, and in your Apex Legends properties, navigate to the General tab, and select Verify integrity of game files. Redownloading and replacing any missing or corrupted game files will take a minute.

Close 3rd-Party Applications
In case the error persists, then open up your Task Manager, by right-clicking your taskbar and selecting it. End all programs from running in the background which could show an overlay while playing the game, such as Discord, Steam, or your browser running in the background. You should prevent programs from running that could use up your available RAM and VRAM.

Update Graphics Card Driver
Ensure your graphics card driver and operating system is up to date. We suggest using the GeForce Experience application for an NVIDIA GPU, but you can also use the AMD driver suite. Depending on how frequently you update your GPU, this tweak can make the most significant difference. In the Drivers tab, simply click on Download and the application will automatically download and install the latest driver.

Update Operating System
When done, search for Update to open your Check for updates system settings window. Click on Check for updates, and after downloading the latest OS update, restart your PC.
