I think we should include a section for frame rate limiting via Nvidia Control Panel/Nvidia Inspector and RivaTuner as the default and easier options rather than SpecialK which can be added as an advanced option.
The correct settings to use for SpecialK for this particular game at the moment is too hard to follow and trying to follow the discussion for it is very messy on the official forum. Kaldaien(mod creator) is an opinionated person and is pushing for using Borderless as better or equivalent to exclusive fullscreen.
Most people want to get better more consistent frametimes and not have to deal with waitable swapchains and flipmode and all the juggling between fullscreen and borderless between both the game's settings as well as the config file for SpecialK.
