Issues fixed[edit]

Blurry graphics[edit]

Set render quality to highest[5]

Missing health and mana bar[edit]

Console command: hud_sf_reload dota_sf_hud_actionpanel[6]

2D sprites and effects displaying over geometry [AMD 7000 series)[edit]

Do not override catalyst control center, turning it off or overriding it with programs like "Radeon Pro" will cause graphical issues in Dota due to poor AMD GPU support, re enabling it should fix this issue.

Pixelated shadows[edit]

  1. To make shadows smoother, go to <path-to-game>\dota\cfg\video.txt
  2. change "setting.cpu_level" "0" to "setting.cpu_level" "2".
