Cemu Thread: Emulating Wii U Games

If it's crashing, you are almost certainly running out of memory while compiling. Restarting did not help in my case, as the RAM usage shoots up very very fast. This is all due to the NVIDIA driver bug.

Seems to be on a case-by-case basis. I'm on a 1070, but with a 17k + shader cache, Cemu is only using 4GB max while running Breath of the Wild. I'm still on 8GB RAM, but compiling never results in crashes.

They really nailed the grass in it not looking odd that it doesn't cast shadow even though so much other stuff does

Yeah, the grass adds fine rather subtle details which makes the grounds look much more lively. If it were casting shadows the result may well look cluttered instead.

Would there be no way to split the workload into smaller parts? Having to compile all shaders at once with such RAM requirement (whether due to driver bug or not) is insane.
 
On Reddit I saw a post and made these changes in the NVCP

Threaded optimisation on
Shader cache off
Performance Maximum performance
Single Display something

I haven't had it crash loading 17k shaders with 16gb ram even once.
 
Someone from the Cemu Reddit posted this:

Nvidia card? Try this:
Recompile all your shader cache data. First delete the shader cache of the game you want to run from the "Precompiled" folder, then delete the Nvidia cache folder under:
C:\Users\YOURUSER\AppData\Roaming\NVIDIA\GLCache folder
Launch a game, let it compile, and ram usage should be under check. Worked for me.

Could be helpful to those with this issue.
 
even with the 19k shader cache my game hangs often for like 1-2 sec just freezing, fps is a mess too. and flicker everywhere. does this only run good with a nvidia card?

Try rivatuner, just add cemu.exe, set 'framerate limit' to 30 and hit enter.
Click to expand...

Did that and it's still speeding up/slowing down. Maybe I missed a setting somewhere? Certainly isn't behaving like it's being frame limited

EDIT: well RTSS is def limiting the frame rate, so it has to be something else causing the speed up

EDIT2: damn looks like it was gpu buffer cache - medium and low both cause rubber banding speeds, but high works fine. Too bad because I lose about 5fps on high
 
Can anyone recommend me a good control setup for this game using a 360 pad? I feel like the buttons I have mapped for other games (mario kart, mario 3d world, etc) are not great for this game at all.

so did 1.7.4c break the hook? should i just roll back for BotW?
Click to expand...

What's the hook? Is that the "video" hack that increased framerates?
 
Hey all, a few weeks ago I installed an update for ZBoW on Cemu using the new method that lets you place the update files in the cemu folders (same method for DLC using that aoc folder). Now that there is another update, do I just replace those or is there something else that I have to do?

Yeap, couple users up mentioned I was just using the wrong version though. After a night of testing, my speed up/slowdown problems might just be that I can't run the game fast enough, consistently enough. Gonna recheck my overclock (i7 4790k) when I get home and see what else I can do.
 
Given the progress this is making, I'm tempted to stop Zelda for a while and continue when it's fully playable on CEMU. I'm about 1/2 way through based on my
Divine Beast completion
and I know I won't go back to the game once finished.

Anyone else going to wait?

Yeah, that's what he's talking about. The vsync disabling thing that's now rolled into Cemu proper

I'm waiting now, but after messing around with it last night, I might only give it another revision or two before I cave. I need some better performance or else I can't hang.

The performance I'm getting right now with all tweaks\hacks\etc is just borderline playable, but not very enjoyable. Getting freezes\hitches, as well as moments of sub 20 FPS gameplay. I rarely hit 30.

So yeah, I'll chip away at it while I play other games and hope that CEMU gets some performance optimizations. I'm not going to be able to get a new CPU\mobo anytime soon....

I'm also hoping that someone manages to mod away the weapon durability.

I get 30fps the vast majority of the time (6700k@4.2/1070) and I still, as of now, would rather play it on my Wii U than on Cemu
Even at 30 locked, it doesn't feel as smooth as the Wii U (when @30 also of course), and I pretty much tried everything (1.7.4c+cemuhook 3.0.1+17k shader cache, vsync off/on, via driver, triple buffering, half vsync, capped @30 with RTSS etc)
Frametimes are not consistent
Add to that the different glitches, freezes, stuck camera etc

This feels like a game that NEEDS to be played at a locked 30 for max enjoyment. After seeing it firsthand in 4K, I wouldn't be able to go back. So I'll wait patiently.... occasionally opening it up and tackling some of the easier content.

This most recent version of CEMU mainly fixed bugs in BotW. I feel like the next big hurdle is performance, and I'm confident that this will be ironed out in a month's time.

Yeeeeeeesssss. This is the best reason to play this game on PC =)
 
Is there a way to confirm the game is actually running at 4K with the graphics pack? It doesn't look clear to me when I do full screen. Took a couple screenshots and they're just 1080p like my monitor.

Are you actually playing on a 4K monitor? If not, it's downsampling and a simple PrintScr will only output your monitors native resolution. Use Shift + PrtScr in Cemu to do a full resolution screenshot. Also, the games ugly post AA might look irritating, use the modded shader posted somewhere on the last pages to disable it.

Good to know someone with a newer CPU feels this way.

Just 1080p monitor. Thanks, I tried Shift + PrtScr though and still only got 1080p.

I really wish emulators could be coded to take more advantage of multithreaded processors but alas..
Click to expand...

RPCS3 (a PS3 emulator) takes advantage of 8+ threads.

Is RPCS3 designed for single-core performance or multi-threaded performance?
RPCS3 is designed to make use of as many threads as possible. This means that processors such as Intel's 8 core, 16 thread 6900K or AMD's 8 core, 16 thread Ryzen 7 1700X will benefit greatly for emulating games at higher speeds. CPUs such as the Intel Core i7-7700K and the AMD FX 8320 will suffice but will not perform equally as well as a processor with more cores and threads.

Nothing like breaking the game by making it easier.

You could say that about any cheat. And that's what this would be, a cheat. Many cheats bypass certain game mechanics in order to make the game more enjoyable.

Would you believe that there is actually a cheat out there called "god mode" that bypasses the DEATH mechanic? I know. Crazy. But people do it.

There are a ton of people that would have more fun in Zelda BotW if weapons did not break. That's the joy of PC Gaming.
 
I tried all the tweaks and i get massive stutter every few seconds. GPU usage drops to 0 and goes back up to 30-40%, 30fps to 4 fps. I just don't understand it.

My specs

i7 6700k , 16GB RAM, GTX 1080
