PokerTracker

Once I turn on PokerTracker, my games become very slow. It takes a long time for the it to switch to a table where it is my turn when I play multiple tables. I now don't even use the HUD. What can I do? Is it my computer? Thanks

What are your computer's specs? (CPU, RAM, hard disk speed and size, etc)
What version of PT3 do you have?
How big is your database?
How many tables do you play?
Which version of PostgreSQL do you have? (see Database > Database Management)

If it doesn't say 100% for all sections in the status bar of PT3 please run Database > Housekeeping - that is one of the most likely issues.
