UT3 Beta Patch changelog:
http://forums.beyondunreal.com/showthread.php?p=2394220&posted=1#post2394220
Under the User Interface changes:
Added framerate smoothing and FOV options to the advanced video menu.
They do not give any kind of date for release. For now, I suggest the solution mentioned here. I'll continue to dedicate some time to fixing UT3 with my program, but I may be wary. If the solution they implement into the interface completely eliminates the need for a fix, then my time and effort will have been wasted, but I'll see.
I already posted this on the last page :) and you could download it from unrealnorth yesterday, not sure if the links are taken down. PW says to delete the .inis to get the slider working but you can still .ini/console the FOV command and it sticks though is limited to 100. A 'partial' fix/workaround for 16:10 but not for 16:9 or 3X users.
Oh and I think looking at it, your fix may still be needed so don't pack away those coding fins/flippers yet, limited to 100 isn't cool... even for 16:10 which puts you at 'almost standard' but some prefer higher anyway.
