Game will run at correct pace on all clockspeeds. FPS counter added. Mods supported (both .pak and loose file types). Autoexec.cfg and other config file loading. – Configuration is saved when quitting through quit. Game saving/loading (current buggy – saved game list will disappear at random). Initial demo playback disabled but operational (On main Quake demos cause a crash when starting game, but on some mods they work fine). – Playdemo command renamed to gpplaydemo for those that really want to see demos. Added launcher app – Clockspeed (133-256mhz). – Graphic detail. – FPS counter toggle. – Mods selector. – Turbo mode toggle Changed menu to support A,B,START. New keymapping: – L: , (default strafe left) – R: . (default strafe right) – L+R: K_INS (+unpress L,R) (default keyboard look) Full chatboard support (can be used in game, not just console).
