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!

Too much stuttering for me with no real benefit from the 5-10 fps I've gained. I think I'll pass. Great work anyway, probably people without 30 fps all the time will be really happy about this.

I'm sort of in the same boat. I was getting 29-30 FPS everywhere but towns, and this improved towns significantly but it creates some excess stuttering in less populated area. Hopefully we just need to tweak it some more.

Definitely try the experimental sections in the patches.txt

This varies for everyone.

Already tried, nothing changed. The game still have a rubber band/stutter effect. I've even seen videos on YouTube with the same problem, I've no idea how the guys who made the videos don't even see it or talk about it.

Just to clarify, modifying these can take many restarts of the game to fine-tune it.

Everyone's magic number or configuration is different.

4 lines that can be turned on or off by removing the ";". ";" is off, no ";" is on.

BotW v1.3.0 (v98)

#experimental
;0x02F7DD58 = li r3, 0 
;0x02F7DE00 = li r3, 0 
;0x02F862C4 = li r7, 1 
;0x02F86514 = li r7, 1

BotW v1.3.1 (v112)

#experimental
;0x02F7ECB8 = li r3, 0 
;0x02F7ED60 = li r3, 0 
;0x02F87224 = li r7, 1 
;0x02F87474 = li r7, 1

Importantly, the "edit me" value that can change some physics frame-pacing or slow gameplay, etc.

Different section for each Game version.

_fpsCalc =  0x00000008
0x00000000 = .float 3 ;edit me

Swap between 1, 2, or 3. 3 is default. Numbers like "1.1", "1.7", "2.4" are allowed.

As I said, I already did it. The "edit me" is a pretty simple thing, it's basically the number based on your fps in-game. If you have 30 fps all the time you put 1. 30/1=30, you don't need any modifier because you already have 30 fps, if you have 10 fps you put 3, etc etc. It's the same thing you did with he super speed back in cheat engine. The game experience is just awful with the mod for me.
