I've been holding off mentioning this until I got a more official reply.
Widescreen Fixer
I wrote this program awhile ago. All it really does is fix the field of view for those of us with widescreen monitors.
I'm posting it now because I've gotten a couple replies regarding its status.
Glenn from EvenBalance said it's not doing anything to trigger a kick/ban from PunkBuster. He said they're going to look into it some more to make sure the program itself couldn't be exploited. This is an unofficial response from Glenn.
EA replied and said that they discussed it with DICE and they gave an unofficial approval of it. They said there's no reason people shouldn't use it. But keep in mind that this is also an unofficial response and their stance on it is subject to change.
For not it appears, unofficially, that is is okay to use this on PunkBuster-enabled servers. Just keep in mind that things may change in the future. When I get some form of official reply, I'll update here.
