What do I have to do if ACTWin 2.8 is too slow and doesn't allow me to do anything?
If the software is too slow, then there are a few things you can try to do to increase its processing power:
Install the application on a powerful computer, preferably on a computer dual core or quad core CPU.
Set the affinity of the application through Task Manager. Press CTRL + Shift + Escape, then switch to Processes, locate the executable for ACTWin and right click it. Choose Set Affinity and mark all the processors. Do the same for Set Priority, instead choose Above Normal or High.
