4.1. Resolution
By default Exult runs at 320x200 (which is the resolution the original Ultima VII used). Exult can use different scaling engines to double the size to 640x400 and increase the quality of the graphics.
Using higher resolutions is considered cheating as you can see too much of the surrounding area. Since the game was designed to be played at a specific size, this can actually lead to plot-stopping problems; hence we will not fix any problem caused by your cheating! Don't say we didn't warn you
Actually being able to play in higher resolutions is one of the big advantages of Exult but as mentioned above it comes with a price.
Within the game you can use the 'Alt +' and 'Alt -' to switch resolution..
4.2. Scaler
The scalers also work with higher resolutions than 320x200. To change the scaling method either use the Exult menu or change your exult.cfg - see 2.2..
Scale2x by Andrea Mazzoleni. This is a non-blurring scaler that looks good without soaking up a lot of CPU sycles. Get more information on this scaler at
http://scale2x.sf.net.
SuperEagle by Derek Liauw. Only 2x.
Super2xSai by Derek Liauw. Only 2x.
2xSaI by Derek Liauw. Only 2x.
BilinearPlus same as Bilinear and it may even be a bit faster..
Bilinear bilinear interpolation to smooth the result. Slower, but looks better. Only 2x.
Point simple but very fast scaler. Only duplicates pixels, no fancy interpolation. Can be used for arbitrary integer scales (2x, 3x, 4x...).
Interlaced identical to point except that it skips every other line to be even faster
The scalers by Derek Liauw are slower but look much better. Try out yourself which one you like most.
