I had to add two more processes to have a fully working pause button, that probably introduced some slowdown on some systems...
Did you try to use the /MIS1 mode as well? (check troubleshooting above)
Yes, it still runs slow on that mode.
I'll figure out a way to put an option to enable the old pause system in version 1.08.
You will be forced to un-pause with enter, but you will not have the slowdown caused by the new pause process.
Alright, thank you!
