I get weird hitching/pauses while using this? What gives? 4750k, 8gb ram, 1080gtx. Could it be the hardrive is too slow to stream the data?

yay: new computer built in time for new preview video

boo: throw away most of my results because performance differences aren't as apparent anymore

Nintendo's design philosophy is so different that even when emulated, their games feel so out of place on Windows.

From color schemes to tutorials and gameplay, Nintendo looks like an alien world.

Wii had this too, but it reached a whole new level with Wii U.

While Wii U emulation is surely exciting, I feel more familiar with the more standardised Gamecube games. I'll skip this one.

Not to me, feels like a gift from the gods, I accept it with open arms ☺️. Heck you can stream cemu with Nvidia shield to your 4k TV at 60 fps. Perfect bliss ☺️

HOLY SHIT. Is Paper Mario actually playable?

👌

Character graphics when they're facing stage right is bugged, they look blank like Peach in the shot. Minor visual ambient bugs. Video cutscenes don't display (intro). Can generally run full speed though.

MK8 and Wind Waker don't crash when you increase their shadow resolution, but they don't scale up like SM3DW does, it's very difficult to notice anything.

Any improvement in XCX?

The performance improvements are pretty much down the line. I don't have an area that reliably runs under full speed, so I didn't have anything for the preview video.

Are you sure you're using the correct texture format to identify the shadow textures? What you're describing is no change, which sounds like you're, well, not changing, the shadow textures.

I didn't describe no change, I said it was difficult to notice anything which is implicitly saying something was noticed at all. Inclusion isn't necessary for graphic packs, the minimum is just specifying its resolution.

Well the newest build now fixes those issues with the shadow res upscaling. Doesn't crash like before when increasing the res.

Although with Wind Wakers case it still blurs the shadows while indoors and depending on the sun direction I believe while I messed with it.

The low res shadows definitely stick out in some places more than others, like the archway on Windfall Island. Maybe try grabbing some screens from there to see if there are more noticeable improvements.

One of these is default, the other is 8192 x 8192

The bigger issue is that it breaks character lighting

I meant the archway by the docks:

This is default. Do you mind testing with a higher res?

Recreating this angle to show the aliasing is near impossible and I only have a daytime Windfall save from the beginning of the game with a different TOD so that specific shadow extends inward.

The issue is that aliasing is contingent on the angle you're viewing the shadow at, so even with a clear example of aliasing, the other half the time the shadow will look normal (unlike usual shadows ala SM3DW). Both of these shadows are default.

Again, the bigger issue is that it's breaking character lighting and I suspect there's no distinction between the shadowmaps. Even if they were separate, since we can only exclude by format at the moment, this could need actual shader modification.

Does the character lighting still break if you isolate the shadow res overrides to affect only format 0x005?

Code:
[TextureRedefine] # shadows
width = 1024
height = 1024
formats = 0x005
overwriteWidth = 8192
overwriteHeight = 8192

Ah that fixed it. How did you go about isolating that?

I basically just used a binary search to narrow down the format. I started with a list of all formats between 0x000 and 0xFFF, and cut the list in half over and over again until I narrowed down the format for shadow textures to 0x005. Probably took between 30-45 min

How do you get past the xenochronicles main menu?
Since I just figured it out myself.. you have have to be on WiiU Gamepad mode in cemu controller config or it won't work.

I just got this emulator working perfectly for me with Steamlink and a DS3 controller. It took some perseverance but it is an awesome result. Dolphin setup instructions for SL helped a lot (disable full screen). I had to take the DS3 controller away from the SL to set it up on my computer. It was tedious but worth it.

As a quick followup to that question about XCX, has anyone figured out how to configure one controller in both Wii U Pro & Wii U Gamepad controller modes and have the settings stick? When I switch back and forth all of the button bindings are gone for one or the other. That makes it kind of tedious if you were playing XCX on Gamepad mode and then switch it to Pro for something else.

EDIT: Or is it just better to bind everything around the Wii U Gamepad input? I'm using a DS3 Bluetooth to the SteamLink.
 
Hi guys, a few questions:

Does Bayonetta2 make a bipping sound really often for you guys? It makes it imposible to play for me =( (gtx 1070, i7 6th, 8gb ram).
And the sound is extremely low, I have to put everything at 100% and I can barely hear it, is
it also normal for you?

And the last one, the options for 1080 o 4K graphics, do I simply need to check it, or do I have to download a texture pack from somewhere else?

I don't know if it's when you shoot or what, has that been fixed in 1.7.1?
 
So what GPU would I need to run pretty much any game at 1600p?

Your GPU largely doesn't matter here. I've seen 760 run games at max. They have maximum GPU usage, but it doesn't hang the CPU. For reference the 1070 I have doesn't even hit 30% usage. It's doing so little work that the fans never start spinning.

It's been said before and it will not change. Your CPU is what matters here, all other components are of marginal importance.


As for XCX improvements, 1.7.1 has made the game stable and full speed for me. I get very few dips in that performance even when action is at it's peak in 4 Skells fighting huge Tyrants. I was not able to do that in any other build. The game still crashes with Host based CPU timer, but it is what it is. In addition to that, with Cheat Engine you don't miss out on being offline and you can play the game completely uncensored. Technically you can play it completely uncensored even without cheat engine, but Cheat Engine just makes it a bit easier.

Man, give this emulator 6 months more and it's going to be really great. It helps that there are not that many games you have to care about emulating.

Yeah, I've got an i5 6600k that runs everything really well. 970 barely notices.

Alright thanks. So what level CPU then do you need? I have an i7 870. Should that be sufficient for most things?

Has there been a mod yet to increase the font size in Xenoblade X? I haven't went through the trouble of installing and configuring Cemu yet but would definitely hop onboard if I could finally read what's happening in this game

To be straight up? Doubtful. Even my i7-3770k was struggling before this latest patch, I have it overclocked to 5Ghz. You might be able to do some of the less processor intensive games like the Mario's, but even then you might not maintain consistent framerates. I mean, worst thing that can happen is you try it and it's not functional right? At the very least then you would know. To be frank though, the 870 is old enough that even a modest upgrade to any of the latest i3's or i5's would be a significant improvement. Even the i7 920 and 930 wouldn't really compete against anything new and both of those blow your cpu out of the water.

Didn't realize there was a problem with fonts in XCX, never been a problem for me. I play with the 4k pack on a 3440x1440 monitor. Latest patch even includes handy black bars on the side. I assume only for Ultrawide monitors, kinda offsets the position of the gamepad screen, but it's a minor inconvenience.
 
Man, 1.7.1 has really smoothed out XCX performance a lot. It's basically running at locked 30 fps now, excepting occasional hitches while assets load in. The bloom issue isn't fixed but the graphics pack workaround someone made for it is fine. The audio is much better now and much less glitchy too. XCX is really completely playable now, the Skell entry/exit bug is fixed too.

The only really obvious unfixed issue is the strange problem of the invisible probe list on the Gamepad screen but that's such a minor thing really.

A quick run-around on Outset Island shows that framerate seems to be much better in Wind Waker HD too, though I'm not really interested in playing through that one again right now.

Minor framerate drops in MK8 and SM3DW seem to be completely gone now and those games easily hold a locked 60 fps with no exceptions that I noticed.

I think next on the list of games that Exzap should work on include Smash and Pokken, and I guess Paper Mario is close to being playable now.

The good news for Cemu is there aren't really that many Wii U games which people will care about being emulated well. This emulator keeps improving by leaps and bounds, soon it will be able to run all the really important games very well and it's only been like a year and a half!
 
I'm not sure if this is the case for all games, but using someone else's complete Wind Waker shader cache causes poor performance. I get a stable 30 starting fresh with my own but experience severe drops into the teens when using the cache.
