HL2 and HL2:DM

[XXzz-Trauma-zzXX]

I was wondering if anyone here had a good FPS config for Half Life 2:Lost Coast and Half Life2: Deathmatch. I wanna play them but Im on a low end computer so I would appreciate an FPS for both if any of you have one. If not can you guys teach me or tell me how I edit my default config to allow for higher FPS and Lower Pings.
