How to fix Dev Error 6068 [Overclock, DirectX, Warzone]

How can I fix Dev Error 6068?

1. Update your GPU’s driver with DriverFix

First, check if you need to update your graphics card driver.

You can do that with the DriverFix Pro software for Windows that quickly scans for outdated drivers and automatically updates (installs) them for users.

Its scan will show you if there’s a more update driver available for your GPU.

This software compares current user driver versions with those in its own driver database, which gets updated daily.

That database includes more than 18 million drivers. So, DriverFix will save you manually searching through a website to find and download the latest graphics card driver.

If you are a gamer, photo/video producer, or you deal daily with any kind of intensive visual workflows then you already know the importance of your graphics card (GPU). An outdated GPU driver can lead to massive slowdowns, lag, and fatal errors.
Your system won’t always choose the latest manufacturer driver for your graphics card. To make sure that everything goes smoothly and avoid any kind of GPU driver errors, be sure to use a complete driver update assistant that will solve your problems in just a couple of clicks.


We strongly recommend DriverFix. This is a safe and resource-saving tool that will be your best advisor for this type of operations.
Follow these easy steps to safely update your drivers:

1. Download and install DriverFix
2. Launch DriverFix
3. Wait for DriverFix to detect all your faulty drivers

4. DriverFix will now show you all the drivers that have issues, and you just need to select the ones you’d liked fixed.

5. Wait for DriverFix to download and install the newest drivers
