Ensure the scaling is set to 100% and that you’re using a normal native resolution. In your in-game graphics settings, make sure to set the window mode to Fullscreen.

Close Resource-Intensive Applications
If the issue persists, open your Task Manager by searching for it in your start menu search. In the Processes tab, make sure to end the programs from running in the background, which could show an overlay while in-game. You should, in addition, end CPU-intensive processes, such as Shadowplay and Adobe Applications, but make sure to only end the processes from running that you know you won’t break your operating system.

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

Windows OS Update
Search for Update to open up your Check for updates system settings window. Click on Check for updates, and after downloading the latest OS update, restart your PC.

Enable NVIDIA Image Scaling (NIS)
If the problem is related to your system performance, you might need to lower your in-game graphics settings. If you’re using an NVIDIA graphics card, I suggest enabling NVIDIA Image Scaling, which will significantly increase your performance. To do so, you should use the GeForce Experience application. Ensure that the most recent GPU driver is installed in the Drivers tab. Navigate to your GeForce settings. Scroll down and enable the Image Scaling option. This will boost your overall frame rates when playing a game on your PC.
