Dota 2 runs well on new ARM based MacBooks. By ToumaKazusa. Posted on Nov 20, 2020 2 7 Currently getting 60+ fps at medium settings at 1280.800 on the 7 core gpu MacBook Air (which is fanless), in case anyone was wondering about compatibility.

Open the Steam client

Command lines[edit]

Multiple command lines should be separated by a space.
Console commands can also be added to the launch options in order to activate it on startup. To do so, add a plus sign (+) before the command and include the parameters(if they exist) after a whitespace.
- Example:To set the attribute r_lod to 0, input +r_lod 0 in the launch options.
