Out of the box, Breakthrough will likely crash or display graphical glitches on Windows 10/11. To fix this, you need the MOHAA Revival Patch or the OpenGL fix. The community-developed "MOHAA Revival" suite automatically adjusts the renderer. Alternatively, manually edit the config.cfg file in the mainta folder (the Breakthrough specific directory) to set seta r_allowExtensions "0" and seta r_ext_texture_env_add "0". Additionally, set the executable (MOH_Breakthrough.exe) to run as Administrator and in Windows 7 Compatibility Mode.
