This is taken from recent post in 2+2 software forums.
I am trying it and will let you know how it goes as I've been getting a little stutter on B2B recently when PT loads up files.
I notice a lot of posts about computer slowdown when playing poker, so I felt i would offer a suggestion for those of you reporting problems when using PT. This should only be considered if your CPU usage ever spikes to 100% (which mine is at pretty much constantly).
In Windows, there are six priority levels which programs run on. Most, but not all, programs default to normal priority. All programs running at normal are treated with the same priority. That is, as far as your computer is concerned, running Party smoothly is equally important as completing PT database functions. Since I consider PT to be a background application, I always start it in "Below Normal" priority.
To set this up, there are a few options. The first, which you will need to do every time you run the program, is via the task manager. In it, go to the processes tab, locate "ptrack2.exe." Right click on it, and you can set the priority of your choosing.
I prefer another option. That is, by setting up a shortcut that starts PT in "Below Normal" priority by default. To do this, you first need to find the file "ptrack2.exe". By default, this is placed here:
C:\Program Files\Poker Tracker V2
Once you locate this file, right click on it and select create shortcut. Find this shortcut, which is what you will be using to start the program from now on, and move it to the desktop or whatever location you prefer.
To set up this shortcut to start PT in below normal priority, right click on it, and select "Properties". For Target, change the code to the following:
C:\WINDOWS\system32\cmd.exe /c START "Pokertracker" /belownormal "C:\Program Files\Poker Tracker V2\ptrack2.exe"
Apply your changes, and you're all set. This shortuct will now always start PT in "Below Normal" priority.
I highly recommend reading up on changing prorities for other purposes. For instance, I always run video/audio at higher prorities so there's no lag. I always run video/audio encoding, database functions, and compression utilities at the lower priorities. Doing this, you can run pretty much as many programs as you want without slowdown, provided there's enough memory.
