Suddenly, yesterday, the game filter no longer works. Instead of a drop down menu there is now a popup window with an error message that won't go away. This is with Internet Explorer.

You have to close the browser and restart.

Unity on Windows is unplayable from the testing I've done, unless I'm missing a special installation or configuration setup that improves performance dramatically.

Is there a better browser to use? FIrefox no longer works.

Very sad this game seems to be dying.

Filter works fine for me.

Since you are a member, download the standalone. See Fizzer's post here https://www.warzone.com/Forum/249786-warlight-unity-alpha-now-available for links.

The browser expirience seems to vary a bit from player to player. So I would just try diffrent things and see what works best.
