So in russian version you can disable epileptic filter..

[Devastat]

I think that in the russian version it is already possible to disable the filter by editing some file like config.ini (this was in the sukhoi forum earlier today). Also Nike-It confimed in another post here that it is possible to disable it in russian version already.

He did not know if it will ever be able to disable it in the western version. So it might be that Western version will just be optimized to work with the filter (offcourse we will lose on something, less graphics etc..)

Another important question is will the russian version work outside russia, as it also has english language, probably no because Steam is region based.
