Running the same process 3 times, looking to prevent throttling between them

[Thomas89]

I'm using Process Lasso as of today and I think I'm already noticing the difference!
I'm multiboxing a Game (which is allowed in it's ToS), and I'm trying to use Process Lasso (or is that ProBalance?) to more efficiently run multiple instances of this game on the same computer.
What I'm noticing is, performance-wise, my PC should be able to run 3 instances of this game without too much issue, however it seems to be that whatever instance is currently active is 'boosted', causing the other instances to drop to a very low Frames per Second.

I've played around with a couple of settings, and ended up with this list of Rules that seems to work best so far.
However I was wondering if there is a setting I can toggle to prevent it from switching 'Priority Class'? I would like to try and see what happens if the active instance is NOT prioritised over the others.

You're on the right track using Process Lasso—it's a great tool for managing CPU priorities when multiboxing. What you're experiencing is likely due to ProBalance dynamically adjusting priority to favor the active window. To prevent the active instance from being boosted, try this:

Go to Options > ProBalance Settings

Uncheck "Exclude foreground processes"

Also, you can manually set each game's CPU affinity and priority class under the 'Active Processes' tab to equalize performance across all instances.

This helped me when running similar setups.

I tried this but unfortunately the same problem keeps occuring. Focussing one window will visibly reduce FPS on the other 2 instances.
