Make STK Look Beautiful Using Your Fancy Graphics Card

STK is one of the most advanced simulation and mission modeling applications on the planet. You can use STK to visualize those missions in the 3D Graphics Window. But, are you viewing STK’s visualizations as clearly as you could be?

When you install STK, Windows automatically configures STK to use the default graphics card that is associated with the computer. Obviously if you have multiple graphics cards, you will want to use the best one! A quick way to find out if STK is using the default graphics card is to zoom in and out of the 3D Graphics Window and look for random tiles of the wrong part of the globe blended in with the right parts. This will look like the image below:
