My textures and models are set at high and yet they appear as mush in the distance and some textures appear to incredibly low res even up close. Is there any autoexec or cfg that will set the texture quality over max, I want the best quality possible.
If their at high then that's as high as they go.
You can't get any higher res than what the developers made it.
There are multiple reskins of players and popular maps you can add which should do what you're thinking of
Set this to game startup settings
(Steam - my games - Counter-Strike source - mouse2 click and propeties - advanced options - type this: -dxlevel 95
Or go to console and type mat_dxlevel 95
Then set everything high and try. Maybe you need tweak some other settings if you already use theese settings..
