Graphics acceleration can be disabled by going to File -> Options -> Advanced and checking the Disable Graphics Acceleration box. However, this feature is not compatible with all graphics cards and can actually degrade performance, cause blurry text, and cause Outlook to hang.

Outlook 2013 uses graphics acceleration to improve performance.You can do this within the Outlook 2013 client by going to File -> Options -> Add-Ins. Try disabling as many of the Outlook Add-ons as you feel comfortable disabling. For example, the iCloud add-on for Outlook 2013 has had many issues since its release and should be disabled if it is not needed. Outlook add-ins can be the cause of significant performance degradation.
