Crispy Doom – a friendly fork of Chocolate Doom that provides a higher display resolution, removes the static limits of the Doom engine and offers further optional visual, tactical and physical enhancements while remaining entirely config file, savegame, netplay and demo compatible with the original.
Its name means that its internal 640×400 resolution looks “crisp” and is also a slight reference to its origin.
Its core features are:
– Enhanced 640×400 display resolution, with the original 320×200 resolution still available in the “High Resolution Rendering: Off” mode.
– Widescreen rendering for using all the available horizontal space of screens with aspect ratios up to 24:9.
– Uncapped rendering framerate with interpolation and optional vertical synchronization (VSync) with the screen refresh rate.
– Intermediate gamma correction levels (0.5, 1.5, 2.5 and 3.5).
– Removal of all static engine limits, or at least raising of the less crucial ones.
– Full support for the “Doom Classic” WADs shipped with the “Doom 3: BFG Edition”, especially the “No Rest For The Living” episode shipped in the NERVE.WAD file.
– Support for all versions of John Romero’s Episode 5: Sigil for Ultimate Doom.
