I've made a fix for the Tower of Judgement entrance stuttering. It is similar to my crystal room stuttering fix (which can befound here:
http://www.titanquest.net/forums/tec...tuttering.html), so I was able to reuse the thread starter message from there.
Get the attached zip and extract it to the Database dir in your TQ IT install dir. So, your Database dir should now contain an xpack\quests\scripted scene_pojandtoj.qst file as well.
The stuttering seems to be caused by the shades entering the tower. So, I simply removed them. Nothing else is affected (I hope).
If you have some problems with it, or a real patch from IL is finally out (...), simply delete xpack\quests\scripted scene_pojandtoj.qst.
