Temporary workaround: Disable hands-free device in device manager or Sound Settings/Record Devices.
Some users are experiencing stuttering/low fps/freezes and Alt+Tab issues when using a combination of AMD FX Series CPU's and Realtek Audio sound, it has also been observed on other combinations, f.eks Intel and Realtek Audio.
If you are having issues as described above, please try this workaround and see if it helps.
Try going In the game, Press ESC and go to Options / Audio / Disable Master EQ.
If that doesnt work:

You may need to restart the game after setting this option. Please try either option and see if it works for you.
Try going to Control Panel, open Sound category/ recordings tab, select active recording device and open its properties, go to the advanced tab and uncheck boxes in the Exclusive Mode..
Completely disable/uninstall all Razer Synapse and Razer Kraken Drivers. Unfortunately, these can cause issues for some, and we are unable to help.
Right-click on the audio icon in the bottom-right tray.
