My PC runs multiple games fine/ never has issues, however since running OSBOT whenever I open anything else,It randomly lags every 30seconds or so, freezes everything jilts for about 4 seconds then continues..? Any fix?

Are you running a script or just opening the client? Also, injection or mm?

How many clients are you running and if you’re running multiple instances make sure you run a new client for every instance instead of adding more to the first client. 

Only running 1, and its running a script -Injection

Does it freeze if you close the client?

No as soon as I stop running the client the freeze stops 

Which script do you run? If it has a lot of flaws it could spike your CPU usage

Also, specs of your machine'?

I have that issue happening to me on my raspberry pi 4 (I'm not joking)

I believe it has to do something with the paint scripters use. When ever I turn it off any script seems to run fine. If I have a paint on it tends to lag in spikes here and there.
