It's still the early version, so expect to see some minor issues.
Thanks to the brilliant work of DrDaxxy, we pretty much have 60 FPS working now. None of this speed doubling nonsense; animation speed is doubled, everything else runs at proper speed.
It is amazing how simple this fix actually is when applied, and I really, really hope that BANDAI Namco sees this and realizes it's perfectly reasonable to add an option for 60 FPS back into the game.
The only thing that remains to be fixed now is aspect ratio on menus, I have basic support for this but it's unpolished. Nevertheless, this is such a significant change that I'm prepared to bump the version up to 1.0.0!
I also integrated a few render tweaks from my Fallout 4 performance project in order to make it more likely for you to sustain 60 FPS. There are some visual issues if your framerate falls significantly below 60 FPS, so triple buffering, VSYNC override and pre-render limit options have been added to d3d9.ini. You can trade input latency for framerate as needed with those settings (-1 mean means driver/application default).
Additionally, there is a new MinimizeLatency setting in tzfix.ini. This setting is intended for people who for whatever reason need to run the game at 30 FPS but find the stutter fix increases input latency. If you set this with TargetFPS=60 I can guarantee you the experience will not be a pleasant one -- leave that off unless you're running at 30!
Kudos to the modding community, nonetheless.
