Citra-CC-Mingw_2_18_01_2018 stay more stable for me some games crash

you use cinebench multi performance mode to compare the 2? don't make me laugh lol.

citra use multicore too it give performance boost with hyperthreading, some games as dragon age inquisition are 30 % more faster with 8 sections ,
on cemu a i5 7600 k do really better because cemu don"t use all core . okay the new are maybe as 35 % more faster with same speed

Cemu can use 1, 2 and 3 cores but it's not relevant to this thread.
Dragon Age Inquisition is a PC Game and it's not relevant to this thread.
Citra does not use multiple cores, it uses only 1. With a dual core, the CPU Utilization stays at around 50% which translates to it using only 1 of the 2 cores.

but the core are used . .

cemu can use up to 3 cores for the recompiler, but it probably uses more cores for other tasks.

The Wii U had a CPU with 3 cores, so they were probably able to split the tasks, because they ran on different cores on the Wii U as well.

citra uses one core (?) for the recompiler and some extra stuff can run on the other cores. Splitting the recompiling up would probably be very difficult, because on the original 3DS only one core was used for the game itself.

But, I'm just speculating and could be entirely wrong. To answer why one does something seemingly better is sort of impossible anyway, since both are far from "finished".

As someone who've messed around in citra's source code i feel like i should chime in. Essentially everything in citra runs on 1 core except from a few things but most of the processing is done in 1 core. What you are seeing when its using all your cores is because of the "threaded vertex processing" added on unofficial builds and is the current bottleneck for a lot of 3D heavy games. Its still not JITted and no vertex cache has been implemented (yet).

I wonder if you ever try playing Citra on one core. As what I've seen from some Citra contributors on their Twitter posts, deactivating most of their cores and only one left will double the speed on Citra.

mine was that build

And the commits used had his "vtx"

For cores, it only helped Nintendo Minecraft Load as far as I know, But think it Should be "Core-1" the 2 ?..

Are maybe ticks used at the time was

No citra runs on 1 core only, those commits does not matter. Those are the simulated 3ds cpu threads which in citra is still managed by 1 core only.

the console may use a cpu core but the loads calculations on cpu multi core before sending data is done

Let me clarify what miguel gomez said

Try playing the official canary release and not the unnoficial one it only uses 1 core. For info why read some of my previous reply

radmaruto · Jan 26, 2018

yes this build use multi core 2 core vs 2 core + hyperthreading

Slidingbass · Jan 26, 2018

defook? he said to test with canary build not the unofficial builds

Sorry if this question comes up so suddenly since i'm always a lurker here and never to bother posting until now,
but are there any builds that actually fixes USUM's Alola Photo Club mode? No i'm not talking about bypassing the black screen.
The Alola Photo Club is a really neat fun feature and i'd like to screenshot them on Citra in HD with the outlines x10 resolution.
If there aren't any then you can ignore my post. I do wonder if its related to QR Scanning camera.

Ah so this is what the actual alola problem is drwhojan asked me to take a look. I never encountered the problem so i didnt know what he was talking about lol.
I'll put up my fix in the next build

radmaruto · Jan 26, 2018

Citra-CC-Mingw_2_18_01_2018 is better in all games for me

Miguel Gomez · Jan 27, 2018

That reminds me to mod the Alolan Photo Club's textures in a "dankier" and "beautiful" way. Too boring to see the same shenanigans over and over again and I'm planning to research about the camera's limits for it too because I'm tired on trying to get my pokemon closer to the trainer and trying to make lewd images of it.

Anyways, some big news for Citra if you thought that they've abandoned Citra for Yuzu Switch Emulator.

@radmaruto @Miguel Gomez @Senjosei @drwhojan What's the currently fastest Citra build, official or unofficial, any kind? I know this question is asked a lot but, I haven't been keeping up and I'd just like to get a simple answer from those who have, being you guys.

If ur not playing 3D heavy games, games that need the software keyboard, doesnt require tick speed hack & would like a texture upscaler try mine

also your profpict isnt yandere enuf

For some reason, Senjosei's recent build makes Smash Bros faster. I don't play Pokemon on Citra anymore since I'm already done playing that game 100% before Christmas.

Out of the box sickc's latest build (20180118) is the fastest for me. Maybe valentinvanelslande's build could be faster if I would fiddle more with the settings.
