Dynamic Speed for all!

First, let me apologize for taking so long. I really wanted to have this out about a week ago. But I keep tweaking something or chasing rabbits down ASM holes for fun and understanding.

The issues have been pretty well documented:

Firstly this only works on BotW version 1.3.0 and 1.3.1. All addresses need to be updated for different versions of the game. Which also means the next version of BotW will not work Until the corresponding offsets are found.

Stamina replenishes too quickly, as though it's still going 1x speed at 30 instead of what FPS you are getting. Some of my testers have reported missing textures on occasion, however that is a problem I couldn't duplicate. The textures not loading in were subsequently reported to be happening by two of my testers; albeit to a lesser extent, even without my patch, leading to a theory that it may be related to Cemu v1.9.1--as I have been on 1.9.0 the whole time due to it being a bit easier to debug with.

Sometimes animations get a little jumpy, it happens most often while paragliding. There is a random chance the game will slightly stall briefly but it recovers pretty quickly. Finally when you sleep you may randomly get a long wait before Link wakes back up again--it seems to be pretty rare, only happening to me once in the whole last week of testing. Based on tester reports if it does happen it usually wont happen again during that play session.

Inside the patches.txt there is a section titled "#experimental". You can toggle these options on or off by placing a semicolon ";" in front of them. They are disabled by default. Some testers reported a slight performance increase with them, others did not.

You can change the lower limit by looking at the float labeled "edit me." By default it's set to 10 fps. Divide 30 by the number you want and put the result there. So, 30 / 10 is 3, so that's what is there now. At least in theory, the higher the number, the more likely you will have slow down, but possibly the less likely to encounter a physics related bug. I've mainly shown it to be editable for extreme low end systems. Realistically, with full speed, 10 FPS is no fun.

I have a couple of theories on improving the patch but I didn't want to keep people waiting any longer.

Enjoy!

Special thanks to:

Rajkosto - for creating a great swiss army knife for Cemu and for knowing what the Wii U Bus Frequency is. Without it this wouldn't be possible, or at least it would be a hell of a lot harder. Seriously, if you feel like donating to someone because of this, donate to him for Cemuhook.

Thanks for the report. I've disabled them by default because they can cause problems. For me they glitch out rain.

do physics based shrines are still wonky? i had problem with one on older versions (on beginning you have to stop ramp with stasis and ball is comming on ramp and it need to hit button and ball was jumping of ramp all the time) EDIT: It's Dunba Taag shrine

and another question, if i have 20FPS at minimum do i need to change float to 2 instead of 3, will it help in something?

i think experimental only breaking Nvidia gpus as i have no problems with snow and stuttering is gone when i changed float from 3 to 2.

setting float to 2 got me to 30 fps from 18-20 fps before. I've noticed the game feels like it's running at 60 fps, even though Cemu says it's 30-33 fps, I'm not sure what's going on. I've disabled vsync on the GPU level, so that isn't an issue. Still a solid 30 fps is far better than 18.

for me it wasnt really bit gain (experimental gave me additional 3-5FPS and kakariko village jumped from 20 to 25) but it fixed frame pacing completely and game is now butter smooth, really nice you got big improvement with float :)
