If your OpenBullet 2 uses a lot of CPU you can try decreasing the maximum amount of worker threads that can be spawned by the process. The default value is 1000, but after some testing we have seen that lower values tend to provide more stability on slower systems.
You can change this value in the appsettings.json file inside the root folder of OB2. FInd the line that says
"WorkerThreads": 1000,
and change it to a lower value like
"WorkerThreads": 700,
Finally save the file and restart OB2 for the changes to take effect.
The default for OB1 was twice the amount of bots being used, so try to use the same value if you’re trying to achieve similar stability.
