Here's a little command line program which will basically try to keep your r_DrawNearFov value locked to a specified value, a value between 60 and 80.
By default it will check for the current value every second, and if it's not your targetFov, it will change it.
Usage:
Start the game first then execute the program as follows:
DrawnearFovFix
Binary is here and source is here.
Warning: I don't know if using this will get you banned, so use it at your own risk. Would be nice if Fellblade responded about this
P.S
If you get an error like "Could not read process memory." try to run the program as Administrator.
