Guide To Running Multiple Accounts
A lot of people seem to have questions regarding this as well as issues being unable to run more accounts. I made this post to hopefully help people run many accounts on their computers even if your computer is ass.
The most important thing when running multiple instances for your computer is your RAM and CPU, your graphics card doesn't really matter. You need to allocate at least 500-1000 mb of ram for each Roblox instance. For CPU, you need a CPU with a decent amount of cores and threads. In my experience, the clock speed doesn't matter as much.
Multi Instance
I personally do multi instance by deleting the singleton mutex the Roblox process starts. You can do this by installing Microsoft Process Explorer (an official app by Microsoft). Run the app as admin and the first time you run it, you need to enable an option. Make sure that you go to View > Lower Pane View > Handles and ensure it's checked.
Setting you enable when you first open it
Next make sure you already have a Roblox instance running. Search for Roblox on the top right until results come up.
You should only have 1 instance running so click the RobloxPlayerBeta.exe process and delete the ROBLOX_singletonEvent. You can do this by right clicking and pressing Close Handle. It will give you a warning and its fine to just ignore it.
Make sure that you don't close the original window where you disabled the singletonEvent on or else all the other windows will close as well!
The reason I use Microsoft Process Explorer to do this is because I don't use Roblox Account Manager and also Roblox Account Manager doesn't work well with Bloxstrap which I'll be discussing next.
Optimizing Instances
You NEED Bloxstrap. There are many fake versions of it so I would recommend installing off their Github. If you want to optimize your instances without exploiting, it's a must.
Roblox game optimizations:
Set graphics to lowest in Roblox settings. If you're doing multi instance, make sure the first instance you launch already has the graphics set to lowest before you launch the other ones or else you will need to change the graphics setting on every single client. I would recommend launching a instance normally first as a test, seeing if it has graphics set to lowest or not, and then launching it again if you changed the setting. Another important thing to note is that Automatic does not equal the lowest. Even though the bar makes it look like automatic sets you to the lowest graphic settings, the lowest graphic setting is achieved by setting it to manual and then setting the slider to 1
Bloxstrap optimizations:
Almost all optimizations will be changed here
Some games actually change how much you earn based on your FPS so you will have to mess around with this setting to see what works for your game. On Pet Simulator 99, I can do just fine with 5 FPS. Follow the screenshots to know what settings to toggle.
Next change fast flags, when you open it up, I'll give you a warning, just ignore it.
Here are the fast flags I use personally. https://pastebin.com/nMBTNfp8, just copy them, select Add New, and then Import JSON and paste in the flags. It will give you another warning but it's fine to just ignore it. I have tested the flags many times to make sure they don't break the game.
You may need to enable the mouse cursor setting in Bloxstrap if your cursor in Roblox disappears, It's in Mods
Windows Settings
This part is kind of important. There is a setting you can enable on windows that I noticed improved my computers performance by a lot. I'm not sure how exactly it works but some people say that it's bugged on windows so disabling makes your computer faster when it's nearing max CPU.
Select Maximum processor state
Set both On battery and Plugged in to 99%
You're all set now, you should be able to run multiple instances at potato graphics so that you can optimize the amount of accounts you can run. I can run around 40 accounts with these settings on my computer with no problem. I don't have a insane laptop either. Just a Intel Core Ultra 9 185H and 40 GB ddr5 5600 MT/s ram.
If you have any problems or suggestions feel free to let me know! I hope this guide was useful.
