Undocumented commands listed are not well understood; please document them if you know what they do
/dtoutline 0/1 renders all non-occluded triangles /testpvs <int> tests number of potentially viewable surfaces /wireframe 0/1 renders everything in wireframe, with wires the color of the texture inside the square /entediting 0/1 determines if entities get selected, useful to texture underneath/around mapmodels /showmat 0/1 shows materials if enabled, allows selection of geometry behind materials if disabled /maxmerge 0/1 sets the cube size where the remipper will end its geometry optimization; higher numbers lower the geometry quantity at the expense of poorer occlusion /floatspeed <int> sets the editing and spectating fly speed /lerpangle /lerpsubdiv /lerpsubdivsize /lerptjoins
/teamalphaname <string> sets team alpha's name to <string>; default is 'alpha' (of course) /teamomeganame <string> sets team omega's name to <string>; default is 'omega' /teamneutralname <string> sets team neutral's (ffa) name to <string>; default is 'neutral' /teamalphacolour <hex> sets alpha team colour to 0xRRGGBB /teamomegacolour <hex> sets omega team colour to 0xRRGGBB /teamneutralcolour <hex> sets neutral (ffa) team colour to 0xRRGGBB (this is what gives the ACE orange/green arenas their colours)
/gamepaused 0/1 determines if the game is currently paused; note that players can still rotate their FOV though their motion and ability to shoot are obviously disabled /gamespeed <int> determines pace of game; 100 is default
/ffa <map> starts a ffa-deathmatch on <map> /insta <map> | /instagib <map> starts an insta-deathmatch on <map> /duel <map> starts a ffa-duel-hard-basic deathmatch on <map> /ctf <map> starts a ctf match on <map> /bb <map> | /bomber <map> starts a bomber-ball match on <map> /dac <map> | /defend <map> starts a defend-and-control match on <map> /race <map> starts a race match on <map>
/gpuskel 0/1 appears to be a gpu compatibility setting; on HD 7570 (Terascale 2) on r600/ mesa 17 leaving it enabled led to 10% better fps than disabling it; YMMV
