Console spam doesn't cause lag and you can suppress console spam with a config command.

You should ask this on the DOTA 2 forums,
http://steamcommunity.com/app/570/discussions/

That being said, http://dev.dota2.com/showthread.php?t=179605
Someone said an old driver, such as WHQL 331.65 actually doesn't have this issue. Take it with a pinch of salt though.

Have a search for other filters to remove console spam.
