Well, because some idiot triggered me, I have enough of doing more research. Project is officially dead from my side.
I'm releasing it here what I have found until now. It's for 1.1.4, I'm not planning to port it to 1.2.0.
Known issues:
- 2x speed movement of MC (I have found limiter, but it looks wanky and it would be better to find movement speed. I saw one cheat that was responsible for changing speed movement, but changing it to 0.5x doubled GPU usage, so it's not good)
- Every HUD element is 2x faster
- NPC speech is desynchronized with their mimics (audio is around 1.5x longer)
- Intro video is frameskipping because of no vsync detection
What has been done:
- Forcing nvnWindowSetPresentInterval to be always 1
- NOPed double buffer
- NOPed one condition just in case to not have issues with render vsync desynchronization
- Doubled some values that were shared also by BoTW that may be related to physics
- Changed global model animation speed to half
- Changed loading and saving icon speed to half
it didn't go any stability tests, so be aware that save can be corrupted, some events may not work, etc.
And absolutely don't go online with this mod.
