How come when I change hl2 to directx 9 mode (mat_dxlevel 90) it sets all the settings on low, and after you change them and use them, then restart, it all goes back to low? Ive tried mat_dxlevel 0 and it set all the options to medium but no AA and reflections to only world, and it always goes back to this everytime I open hl2 as well. Anyone know how to fix this?
