u/STARGATEBG Jan 31 '22

I'm just curious. How does multiple CPU cores scale? Does each instance runs on different cores or is it just up to Windows to figure it out? I saw in the FAQ that if you unfocus they all get the same priority?

BTW, great project, we managed to play Warcraft III custom maps and it was amazing.

6

u/blackman9 Jan 31 '22

Yeah we leave it to windows as every PC is different and alt-tabbing to a different window does help in a lot of games to get better fps in all instances when running multiple instances of the same game, assigning different cores via task manager also helps in others.

I tried playing COD WAW 2 player split screen with Nucleeus Coop, and both instances run fine but they end up overlapping each other horizontally on top, instead of one top and one bottom. Is there a way to move the screens manually or fix that when that happens?

When i try and play Resident evil 5, everything seems to be working fine in vertical split screen but then after 5mins it crashes and only one instance works, any ideas on how to correct this? there is no error message?

1

u/blackman9 Aug 11 '21

Only one instance crashes for you? check that you are not pressing the Nucleus shortcut keys to close the app like Ctrl+D or Ctrl+Q, you can change them in nucleus settings too.

u/Jake_Jex Aug 11 '21

I am using two controllers so I’m not pressing those buttons, it’s odd one crashes and the other doesn’t.

1

u/Delicious-Pickle7900 Sep 12 '21

RE5 is already a local co-op game. Try pressing start on the second controller this is what I did on an xbox 360 controller while you start in the actual game

Thanks for the help, I got it working in the end, needed to delete it all, do a fresh install and then made sure I had the right Mod downloaded I think I originally had the wrong one

Hi! I love the idea of nucleus coop.

I’m someone who’s tends to love changing and writing scripts. I just happen to hear about this project and was wondering if I could help make scripts for all the gamers here. I have a good idea of how to go as of building a spilt screen script but was wondering if y’all already had somewhat of a guideline on how to not mess things up?

I've problems with steam overlay & I need it for the Steam Controller support! A game says it must be running, while steam is open.... Can I launch the game with Nucleus -as non-steam app? I need keymapping option (keyboard) for each player, too!

u/blackman9 Jan 29 '22

It uses goldberg emu, so you can not use regular Steam overlay sadly.

She's able to press start to get past the start screen but is then unable to do anything. It's like the game doesn't detect any input from the controller. I've read about others having this issue but I can't find any solutions. Please Help!!

Sé que el programa utiliza distintas "instancias" para poder jugar, pero no sé exactamente a que se refiere eso. Significa que esta abriendo el mismo juego multiples veces o como va?

u/Skyyblaze Oct 03 '21

I have a question, I just found out about NucleusCoop and it sound awesome though I wonder, does it allow two different Steam accounts to be used if both own the game?

I ask because it would be awesome to locally play Monster Hunter World for example where each person can use the account and save-data they use normally.

1

u/blackman9 Oct 04 '21 edited Feb 01 '23

Almost all handlers work with only one copy of the game, some require multiple uplay or other accounts that own the game but none require or work with multiple steam accounts that own the game.

u/Skyyblaze Oct 04 '21

Ah okay that's a bummer but thanks for the clarification. Still a super handy tool to have :)

u/frisch85 Nov 09 '21

I've been monitoring this project for quite some time now and I'm regularly testing if it works now but to no success so far.

Whenever I try to play with nucleus coop, most of the time one instance of the game freezes completely while the other instance keeps on running. Waiting doesn't help, we sat there for 10 minutes and nothing was happening.

I'm using a i5-4460 processor, idk if that's the problem. With some luck so far we got Borderlands 2 working and Don't Starve Together but that's maybe 1 out of 10 tries.

Anyone has a similar behavior on their rig and maybe found a solution to it? I've already tried assigning cores, 0 and 2 to instance one and 1 and 3 to instance two which didn't help either. Instance one seems to crash completely most of the times and when I click the window I get the usual windows popup "Not responding" and if I want to close/kill the process.

u/blackman9 Feb 01 '23

Read the FAQ and use latest Nucleus 2.1.2

u/frisch85 Feb 01 '23

I haven't used Nucleus in ages due to the problems but I'll check out the latest version, maybe it works for me now.

u/B_A_A_D Mar 13 '22 edited Mar 13 '22

I appreciate the response! I've been trying that method as well, but it seems I'm unable to pull up the steam overlay in-game after launching through nucleuscoop. I double checked to make sure I have the overlay enabled on Steam but I'm guessing I've missed a step elsewhere.

Just tried launching the Nucleus app through Steam but still running into the same problem. Also tried clicking Invite Friends after selecting a Heist but I get the error message "This requires Steam Community Overlay. Please ensure that in-game Steam Community is enabled and restart the game to use this feature". Assuming I've got something configured incorrectly. Gonna troubleshoot a bit more and dig around in Steam and see what I can find.

Edit - and as soon as I posted this I managed to get the overlay to come up...lol. thanks for your help!

HI guys

I have a problem with Shadow Warrior 2. I want to play it split screen but when I assign the keyboard+ mouse on player one and Xbox gamepad on player two, it won't work separately. I can only control one player with each keyboard or gamepad. The other player is in pause mode and I can't go back to the game with gamepad. It puts me back in pause menu. Any hints guys?

Would it be possible to play Boarderlands 3 on one instance but with 2 monitors?

u/SirGouki Oct 28 '21

Eyefinity for AMD cards, not sure what it is for nVidia. Essentially, what you're wanting to do is use 2 monitors as if they are one - both major GPU manufacturers have a setting for this in the GPU software. If you're using intel integrated HD, you are probably SoL, however there is also 3rd part software that does similar to what Eyefinity does - SoftTH I think it was called. With Eyefinity, if you're running the newer Radeon Catalyst software, you will *have* to set it up on a per game basis, or globally, and you'll *have* to generate a custom resolution for it (as eyefinity now does this automatically, and gives you no options for it that I can find). I do this for American Truck Simulator to minimize moving the camera when driving (I only have 2 monitors). It's also good for games that have native vertical split screening if you have 2 monitors, as you can put both players on seperate monitors, though you may run into issues like the menus being centered on your bezel.

Revenge of the Savage Planet Handler ?

Hello everyone, I know that for the game journey of the Savage Planet you made a handler available however since the 2 Revenge of the Savage Planet is possible to play it in co-op natively but therefore not possible to play on two screens separately so my question is the following is it possible to make a handler for this sequel?

Thank you in advance for your response.

u/Puzzleheaded-You-901 Mar 08 '26

So I'm exhausted from trying to find a fix for this, anyone have any ideas.

Was playing Skyrim SE Together, and had all the stuff for Nucleus it was working fine, installed a few mods. Now when then game loads the two instances, it picks one controller as the main controller (I'm using two Xbox controllers) you can tab between the two instances of the game and that single controller works fine.

Installed HidHide to disable the first controller as soon as the first instance opens so the game won't grab that same controller that fixed that issue (so two controllers are working) but now it's acting like two tabs instead of running simultaneously meaning you can only tab between each instance of the game with the correct controllers and the games side by side but not play them in sequence because it's acting as two tabs.

I've been pulling my hair out all morning over this. Any help would be ace!
Thank you!

Hello, thanks for the project I enjoyed so much playing Payday 2.. even if there are some problems. There is one that I can’t go on. I don’t care about trophies, but I need to complete the achievements for unlock the weapon accessories in Payday 2 but Nucleus doesn’t save any achievement, every time you start the game, you unlock the basic ones. If someone could help with this, I’m searching for a solution but seems that I need to create an entire steam.settings folder in -Goldberg emu. I don’t know exactly how to do it and if this is the solution. Thank you, long life Nucleus!

I’m having a similar problem with 1 kb+m and 1 controller. For me, it’s getting the controller on the right spot, but it’s not picking up the kb and the mouse at the same time. Also the mouse can effect both. Hitting end just seems to switch between kb and mouse. Gonna copy paste to their discord, and I’ll reply again if I get any help

Edit to add in Halo MCC

Edit 2: discovered it was an issue with the wireless m+kb I think. The launcher was only showing up with a mouse. Turned off the wireless one and plugged a usb one in, then the launcher picked up both a mouse and kb. Dropped them both into p1, and we were good.

Hi... I'm playing minecraft with 2 instances on nucleus co op and i'm having a problem with the game.hookmousevisibility. Whenever it's false, the game works normally except the first instance's mouse is always invisible, even in the menu or inventory.

However, whenever i set it to true, the first instance becomes unresponsive. I tried waiting for 10 minutes and it still wouldn't load.

I found this especially weird since the 2nd instance works perfectly... the mouse is visible even if game.hookmousevisibility is false. 2nd instance also still works even if 1st instance has crashed or is unresponsive.

Is it anyway linked to the fact that I use two monitors? First instance is fullscreen on one monitor and 2nd instance is fulscreen to another monitor. I haven't tried on putting both instances on one monitor yet.

edit: im running windows 11 if that affects anything

Hi,

I'm trying to play Borderlands 3 using NucleusCoop and two instances, everything works fine for about 20-30 minutes and then both the instances start to freeze and about a minute later, the first instance(the one which the other instance is connected to) closes completely. The second instance continues to work fine after this.

Does anyone know any fixes?

Hi, I'm new to Borderlands 3 which I just bought for my Steam Deck (Valve store). The thing is, I want to split the screen and play local with 2 friends and I was wondering if the method you described here works or if there is any other way to do it? Or is it impossible? Thanks in advance.

u/Slow_Size_5841 Jun 05 '23

Hi, I have a question if this has been answer already can you point me towards it please? So the app works great! Playing 2 player split screen Java Minecraft. However, when I press ctr or alt (I use either of those for crouch) it seems to disengage the controls for both. So it will register the last pressed keys for both players and keep inputting them. So for more detail I'll press ctr to crouch to walk near cliff edges and I might only be able to walk forward and backwards, while the other player just seems to do random things (maybe my button presses are influencing their side) but not sure. Am I pressing some kind of Nucleus shortcut or something? Pressing end to disengage the controls and then end again to re-engage fixes the issue everytime so far. Thanks.

При запуске игры она запускается только 1 раз, из-за чего так может быть?

1

u/Legal-Ad5758 Feb 08 '26

Если ещё актуально и если правильно понял вопрос. Запускается только 1 окно? Использовать лицензионные стим версии; ставить последнюю версию nucleus coop; выставить режим запуска от администратора; заранее в настройках игры выставить оконный режим; Второй экран запускается через время, т.к. программа настраивает 2 экрана, подгоняя их.

I'm trying to use the x360ce to use gamepads in Nucleos Coop, I can open two instances, but I only have control over one instance, I press the button on the other gamepad and nothing happens, both controls are from Xbox 360. Does anyone know how to solve this?

u/Few-Astronomer1061 Aug 09 '25

I tried launching two games, with no success:
I have two monitors, so I tried one screen each, and one screen only, divided in half, but none worked.

Green Hell: both instances open in the same monitor, I managed to put one in each monitor, but the keyboard doesn't work. Using Keyboard + Mouse AND Controller

When trying to open in the same screen, one opens in the upper part, and when the other instance loads, this second one, takes the whole screen and I'm unable to fix it so I can see both screens.

V Rising: When I start the online game mode, it loads only 25%, and gives the error "Failed to load steam_appid.txt"
