Cemu Thread: Emulating Wii U Games

What? there is a pre-cache system. You can even download "transferables" ready caches that other users sharing. I will take long to compile the first time tho.

What what? If you don't have any precompiled cache, it gets built thru time, as long as you play. Look you said it yourself: you can download premade caches.

And did you asked yourself how those premade caches are made? By playing the game.
 
6700K, 16GB, 1070.

and yep. got the hook installed, capped with inspector, set affinity, customised nvidia control panel, tried both my own shader cache and one i downloaded.

with my own cache the game constantly stutters. with a shader cache it won't even load the game because it crashes all the time.

It will stutter till you hit 8k+ in the cache. I'm at 7k+ and it's not stuttering as much. Some people say to play it with your own cache as they claim it's generated with your system specs in mind, but I can't confirm whether that is true or not.

Thanks.
When eventually i'll upgrade my PC, i'll try again i guess.
To upgrade CPU i have to upgrade MOBO, which will require DDR4 ram, which means upgrading that as well, which means i'll probably also have to upgrade my old ass PSU, too.
It's a lot of money for just one upgrade.

BOTW seems like the type of game that's gonna be just as fun in a couple of years, as it was this one anyway (it's not like it's on the bleeding edge of graphics or anything) so no rush.
Besides i did play about 10 hours on WiiU already, so i got my fill.

It really is a great game and while I have sunk maybe 90 hours into HZD, I already have 120+ hours on Wii U BOTW. While playing this, the thought of portability crossed my mind. This game is perfect for Switch and sells the system, IMO. Once MO drops, I'm getting that, Splat2 and BOTW in the same get.

Fuh.

I'm thinking of installing CEMU now, but I'll probably wait a while. Is it as easy as installing the emulator and configuring resolution and stuff, or is it more involved than that?

You can't configure anything in the same way you would in Dolphin. You instead have to use "graphics packs" (glorified text files) that allow you to alter the resolution/filtering/AA. You can find and download them online, but Cemu should come with a number of basic ones already included. So instead of just selecting your desired rendering resolution, you have to go into a graphics pack menu and check a box next to the pack that has the resolution you want (most packs are either 1440p or 4k). It's a little bit of a let down coming from the ease of use of Dolphin, but it works, and 4k is probably where you'll want to be at anyway due to the performance hit being relatively small compared to using native res.

so, building your own shader cache means the game will stutter all the time? i am playing BOTW so my query is about that game in particular.

my system

i7 2600k @4.5
16 gigs of ram
1080 ti
windows 10

I got Xenoblade Chronicles X running on cemu with high res and everything, and while the graphical glitches are minor and far outweighed by the resolution boost, the audio crackling is just absolutely unbearable. With XC2 coming out in months for the Switch I don't know if I'm ever going to get to this game...

A few seconds in most cases, depending on the caches. For example, when you run into the open world view at the first time, the game will be freezing for a while because Cemu is compiling them. Then you smack a bokoblin for the first time it'll freeze again for a second to compile the 'smack' cache. Then in another instance, you're pulling your fire arrow for the first time, and it freezes again to compile the effect. But after playing for a couple of hours or so it'll be mostly freeze-free in my experience. Of course it'll be compiling again when you reach a new zones with new buildings/enemies/etc.

I'd love to know what sorcery is this person doing, i have a 2600k @4.5 and with the patch the game never goes above 30 and runs at half the speed.
From what I've seen, all these emulators (cemu, dolphin, pcsx2) run much better on CPUs past ivybridge. Dolphin for instance benches just as good or better on my laptop (stock i7 6700hq) than on my desktop (4.6ghz 3570k)

Seeing this makes me want to double-dip even though I have the Switch version, wow o.o

I also wonder though, what OSD is used here with the framerate-graph?
I finished the game on switch, discovered all the shrines and unlocked all the slots for gear and i am replaying the game again on CEMU, even running the game at 1080p makes the game looks better and at 4k the art looks gorgeous, if you have a pc that can run this game i highly recommend you give it a go.

You have a 2nd generation intel (Sandy Bridge), but the CEMU works best with 4 - 7 generation (Haswell - Kaby Lake). Some new tech that 2nd generation dont have. More or less this.

Anyone knows what kind of performance I could expect with an i5-4690k (stock for now)?

I have a i7 4770k (so very similar I guess) and a 1070 OC card. I get ~25FPS when the processor is at stock. Varies from 22 to 30. I have applied all the FPS boosting tricks that were there. When I overclock the processor to 4.3GHz, its mostly locked 30FPS. very playable.

That's very good to hear, I'll definitely try it out once I get a cooler and (finally) overclock it :D

Alright thanks good to know! I'll put it on the list for next year then as I want to enjoy it with all bells and whistles then and my current 3570k @ 4.4ghz won't cut it.

Hey everyone, I just got a PC able to run this so been experimenting.

Got Mario 3D World and Mario Maker, and have gotten pretty decent performance on both, 3D World is running with a cache I found on reddit.

So I got some issues, I got Mario Kart too, but I can't get the cache to load, it freezes at 8801, tried with two caches but the same happens with both. I've read that this has to do with RAM, but also that it doesn't, I have 8GB.

Second is a more general glitch or sorts, the screen just freezes but the game keeps going, this has happened with all of my games, to varying degrees, on Mario Maker it happened the one time, maybe a handful or so in 3D World, I've seen it constantly on Mario Kart.

While the PC is good I don't have a dedicated graphic card just yet, so I'm using the built in Intel GPU, which is not officially supported, I know, but still would like to know if anyone can help out.

I'm running the latest public version of Cemu, with an Intel i5 7700k and 8GB of DDR4, I also have 16GB of Octane memory, but not sure how that helps.

Dude's running it at 4K, though, so these videos aren't exactly helpful. Wish he'd just run it at 1080p so the vast majority of us could get an idea what to expect with this patch.

Dolphin runs great on Sandy Bridge no problem. You can do 4K with extras in a lot of games. Ishiiruka takes care of the rest. Ubershaders are there if you have a lot of power.

On a modern system Cemu is completely CPU limited at those resolutions, so it doesn't really make a difference.

Well I mean you need to overclock an i7-7700K to 5 ghz to get actual 60 fps with the patch.

I think most of us aren't working with overclocks like that, so the 60 fps dream is still a distant one.
Well, unlike the previous patch this one allows arbitrary framerates, so even if you just get e.g. ~45 FPS (which seems viable at ~4 GHz) you benefit from it. (Especially if you are on a VRR monitor)

Are they straight-forward to understand? I guess I should look into it eventually.

Impressive
He's got a beastly CPU though (7600k @5.3GHz)
Doesn't get any better than that for emulators like CEMU

Edit: he also has a CPU speed comparison

Yeah I sold my Wii u and moved my Zelda game to CEMU. Looks so much better. Even though my machine is middling it’s still 30fps for the most part and certainly not worse than Wii U wrt frame rate. Then add higher res and its sweet. Still the odd glitch of course and motion stuff doesn’t work (I play with Wii U pro controller) but great.

I hadn't played BoTW for some time on CEMU and it looks like things have changed.
First time I'm seeing my GTX 1080 with 90%+ GPU usage (playing at 5k but still, it was never that high before, far from it)

I'm getting 40-50fps on average with a 6700k @4.2GHz but it can go in the 30s in some demanding situations

GPU buffer accuracy not set on low?

Isn't medium recommended?

Low is recommended for Zelda and one of the updates to Cemu a while back fixed a lot of smaller graphical issues at the expense if more GPU power which is probably what you're seeing.

Trying to figure out why the pack isn't working for me. I'm stuck at 15fps. :(

Game, decrytped, updated through maple seed, copied all folders from the updates to the game folder. Using latest cemuhook, and enabled to new patch in graphics pack option.

Not sure where I've gone wrong.

Medium. Low does not do much compared to Med? I think the problem was I had it at 8K and something about cemuhook. Now mostly 30-40 in Kakariko, dipping to high 20's.

F34R: If fenceskip is making it better, then it's not working. I copied all elements of Cemuhook folder into the 1.9.1 folder, instead of only dbghelp.dll. Then it worked for me. Also make sure you don't run it at 8k or something.

Did you copy everything from CemuHook 5.3.2 into your main Cemu directory? If the graphics pack isn't work, it's likely a problem with CemuHook files.

When the game is running, Options -> GX2SetGPUFence skip

Isn't medium recommended?

Realistically as a rule of thumb, medium may as well not exist. You're basically only ever switching between low and high.

The Fence Skip option actually doesn't need to be enabled in order to make use of Xaliphenos's framerate patch.

Ah, I've never used a patch that enabled gpufenceskip. Low performance/15 fps is just something I automatically associate with it being disabled.

Yeah, you'd be exactly right. With part of X's patch being to remove any sort of framerate caps (at least up to 60 fps?), the fact that he's still hitting that 10-20 fps wall is indication enough that the patch simply isn't being applied. I had a similar problem, which came down to a fresh install of CemuHook 0.5.2 and making sure that all of the necessary files from there were copied over to the Cemu directory.

HOLY FUCK THIS PATCH

1 month ago I tried dabbling with CEMU and was only getting around 20 fps in BOTW. Run a Ryzen 1700@3.9, 1080ti, 16GM RAM. This god damn patch man. I'm getting around 38-50 FPS in the overworld. Now I am able to truly appreciate Zelda BOTW @4k, high res shadows and removal of the in-game AA. Started my cache from scratch.

I'm obviously late to the party here but what a game changer. So much of the art is held back by the low res on Switch. What a beautiful game. Hoping performance will be better/more consistent than the Switch though, noticed a few slow downs when my daughter was playing the game. I've mostly just screwed around in the Switch version, but with this level of performance on PC, it's time for my first play through! So hyped!

This is the first time I've come to regret my Ryzen purchase... if I had the 7700k I would have tried to at least clock it 5ghz+. That would have got me closer to 60 FPS Zelda. Ah well. I am going to disable weapon durability I think, just am not a fan of it.
