I have a project with 20 tracks so far. Pt. plays those tracks with hardly any CPU usage. I loaded the same project in cakewalk by band lab and got glitches, with audio with the buffer set at 256. No problems with pt. at this setting. I still had problems with cakewalk with a 512 buffer. Pt. is the main daw I use. I upgraded my pc(i7 processor 16GB ram 1TB SSD for windows and my projects are stored on a 4tb usb external drive. I was wanting to go for another daw, but I might be sticking with pt. Pt to me, does audio fine, but is a little weak with midi.
