Quest: To Play TF2 Decently on a crap machine
Progress:
First FPS: 20 in spawn, 5 in midfights
Turn the Quality down
Quality Config: used m0res max frames, let my graphics card handle textures "mat_managedtextures 0", reduced particles effects "mat_reduced particles 1", Disabled HDR "mat_hdr_enabled 0" - added to config
Defragment
defrag windows and tf2 - improved fps by about 5%
Advanced Graphics Tweaking
Graphics BIOS Tweaking: Did the LOD texture trick and set it as low as possible using ATI Tray Tools, also overclocked my graphics from 200mhz core and memory to 250mhz - added 80mm fan in case over gpu to keep cool.
Further Progress
FPS are 60 in spawn, 30 with team mates, 25 midfights
Well that's bearable
LASER-FUCKING-WEAPONS: 5fps.
