It might be worth checking with the dealer that it has the latest software patches applied (assuming it's not a new M3). I last had the DCT software updated on my M3 18months ago and it did make an improvement. If you're car is older than that and not had the update, then I'd push the dealer for it to be applied.
I've become lazy and I usually drive it in the default D2 mode, and it's certainly not jerky.
