• Set this to Standard Datastream (see below). Must be done each PRT session.
• Use V11.
• Use fewer Detailed Reports (no matter they don’t collect the data in real time (checkbox).
• Have more memory in the PC/Laptop.
• Set charts to rougher timeframes (I know, we don’t want this, but it helps). In the same realm : zoom *in* more (less data in the viewport).
• Restart PRT an hour or so before opening hours of US (read : have it all clean in there).

As you already noticed, it is all about volatility. Nasdaq is the worst regarding this, with ~10000 “ticks” per second at the opening on an average day. It could be sufficient to have the measure of what you see below only during the first ~30 minutes after the opening; don’t let it choke and be gentle with your PC during that period of time.

Have you ever run the “Computer Performance” test (under “Help”)? This scan is specifically designed for use with PRT and provides insight into how the different parts of your computer (CPU, memory, rendering) handle PRT.
Each component receives its own score (Processor score / Memory score / Rendering score), and together they form the total score:

• Less than 150 = insufficient

• Between 150 and 250 = sufficient

• More than 250 = excellent
  This test helps you identify the strengths and weaknesses of your computer when using PRT.
  In my case (see screenshot), the processor performs well, but both memory and graphics score moderately (built-in graphics card). The solution: install more memory and upgrade to a better graphics card…
