How does window size effect performance?
Larger windows take more processing time to draw or refresh images. Smaller windows will produce smoother graphics. In general, slower computers will require smaller windows. Experiment with different windows sizes until you find an optimal size for your hardware setup. You can see how fast your rendering speed is by looking at the frames per second (FPS) in the bottom right corner of the Traveler window. 12-15 FPS is average.
