Chocorenderlimits is a fork of Chocolate Doom by RestlessRodent, it is designed for playtesting levels for vanilla Doom. It displays counters for visplanes, drawsegs, etc. to help determine the location and the time that a static limit was exceeded. It was initially created for Sarah Mancuso (esselfortium)'s project which recreated Knee-Deep in ZDoom for vanilla (Knee-Deep In KDiZD).


Chocorenderlimits is able to display the following information:

Along with that, you are also able to:

  • Teleport to the location where the visplane count maximized.
  • Draw the visplanes in view with either a border or a solid fill.
  • Brute force the level and show locations where overflows are the most likely to occur.


RestlessRodent has retired from maintaining Chocorenderlimits. The state of the project has been preserved in a render-limits branch within the Chocolate Doom source code repository, but is still in need of maintainer(s). The latest version is based on Chocolate Doom 1.5.0.

Julia Nechaevskaya ported Chocorenderlimits to SDL2 in a fork, based off Chocolate Doom 3.0.0 which later became a base for CRL, a continuation source port.
