Turn Off Hardware Graphics Acceleration in Outlook

Ask a question

Hardware acceleration is a technique in which a computer's hardware is forced to perform faster than usual. This technique is used with computing tasks that require more power and processing, such as graphics or video processing.

Unfortunately, using the hardware graphics acceleration feature can sometimes slow down a program or your computer in general. If this happens, it's best to turn off the feature to get your computer running normally.
