Fortunately there are a few things you can try before contacting the developers. The first thing we recommend you do is make sure you are running the game as administrator, so just close it and reopen it by running it this way.
Make sure that both the operating system and all drivers are updated to the latest version available.
We also recommend using the "Scan and Repair" option in the Battle.net Launcher in the Warzone menu.
Run the game at 30 FPS tops.
Delete the game data folder to force an update.
Try playing the game in the "Borderless Window" option.
Close applications that are running in the background and that may decrease game performance.
Lower the graphics settings and install the shaders in the graphics settings again.
And as a last option you can reinstall the game.
