Valve releases a new experimental feature for Dota 2 to speed up loading times

The “-prewarm” command can be included in the launch options to speed up the game, especially on lower-end systems.

On July 31st, Valve has shipped a new update to Dota 2 which aims to speed up the loading times of the game in lower-end systems. Lately, there has been a surge of people complaining about being stuck in black screens while loading which might be a consequence of all the new features from the TI10 Battle Pass.


From now on, players can use the “-prewarm” launch option to load up most of the in-game assets during the initial launch of the game. This means that players will have to face a bit more time during the initial launch to fully load up the game, but the loading times when connecting to a match will be much faster.

This command is especially aimed at players on lower-end systems, who were facing difficulties connecting to games and were often receiving abandons for not being able to connect to the game in the given time. Not to mention being stuck in a black screen was also annoying for the players which this launch option appears to fix.

To use this experimental feature, simply right click Dota 2 in your Steam Library and click on properties. Then go to “Set Launch Options” and type in “-prewarm” without the quotation marks, and that’s it. You’ll face a longer initial loading time but chances are, you’ll have a better gameplay experience after you sit through the initial launch.
