In the Device section is where you will find the information about your video card. Take a moment to look at the "Approx. Total Memory". This is how much memory DirectX thinks your video card has and should be 32.0MB or more.

The Drivers section will tell you what version of video card drivers you are running, along with the date of those drivers. Typically you want to keep this up to date, as video card manufacturers are always correcting and updating video card drivers.
If you think you need to update your drivers, then go to this page for information on how to do so.

In the DirectX Features you need to make sure all the options are enabled. If they cannot be enabled, your video card is not going to work properly in Aces High II. The two test buttons in this section perform very simple tests. As such, do not assume, if the tests run, everything will work.

The Notes section might have some hints to any potential issues.

If you are still having issues and find all this confusing, then simply use the Save All Information button to save the DXDIAG data to a text file and email that file, along with a description of your problem to support@hitechcreations.com
