We don't know yet
- if the filter will stay for the western version (there is a possibility Ubi decides to take it out or make it optional if that is feasible technically)
- what is the real performance loss from this filter. Luthier said 10 fps on low end machines, but given the track record on communications, sorry, I have my doubt. some already report a loss of about 2-4 fps
http://forum.1cpublishing.eu/showthread.php?t=19604 , some say it's more (see mysticpuma thread)
There is obviously some work to be done about something else than the filter.
Oh, and I do not see what gain Ubi would have to trash the game. If it doesn't sell well, it's Ubi loss too.
