Scalers and supported resolutions

Postby junglemontana » 2019-2-16 @ 19:20

Is there any documentation available about the resolutions that are supported by each scaler option?

As you may have noticed, the scalers are not always used and this apparently depends on the current resolution. Adding "forced" to the scaler option will enable the scaler for all supported resolutions, but some scalers only support certain resolutions. For example, the hq2x scaler does not seem to work with 800x600 resolution and Dosbox prints a message to the console: "Scaler can't handle this resolution, going back to normal".

Of course one can set the window or full screen resolution to a desired value and use output that supports hardware scaling, e.g. opengl. But I, for instance, like the visual quality provided by some of the scalers so I'd like to use them whenever possible. So having the supported resolutions listed would be helpful.
