I can confirm that. I lowered all the settings but the lag persists. Didn't know about the workaround. Will try it now, @natewiebe13 thanks for the tip.
The Workaround solves this issue. Maxed all settings up and the game is still very responsive.
The next client will have a fix for this.
Did this improve with today's update?
for me it's fixed, anomaly works with overlay now.
Thanks, closing.
Nothing extracted yet.
In Anomaly Warzone Earth. You get 2+ seconds of mouse lag in the menu and ingame.
A current workaround is to disable Steam Community In-Game through the game's properties.
