I wanted to stress test my new Macbook Pro 14 with M1 Pro chip and 16GB of RAM, but I went into some strange behaviour - glitches, CPU spikes, you can hear and see it in the video below:

Granted, I have a fairly low buffer size on my LIne 6 Helix audio driver - 128 samples. But higher buffer sizes don't help much... I also tried it on Macbook's internal audio - same behaviour. I am using the newest Kontakt 6.7.
A friend of mine did the same test (I sent him a Cubase project with similar midi notes as those played in this video) on his i9, 128 GB RAM, Windows machine, with no glitches and with extremely low buffer sizes. I wouldn't take 128GB RAM into account, since this instrument is a very small pressure on the memory.
Any thoughts?
