Yup, pretty much.
Not exacerbated, but also not better. It's about you'd expect from a one-size-fits-all approach, but I'm being told it's getting better. The world will be a better place once it is up there with the likes of RME, MOTU, Lynx etc.
At what buffers do you have them? Also, if memory serves, you mostly run Kontakt in Bidule? Kontakt is pretty efficient, although it is also library-dependent.
In my case, having layers of Keyscape/Omnisphere in combination with Zenology, HalionSonic, Kontakt and whatnot, 128 is too ambitious for many audio interfaces. When I use a Montage or Fantom as audio device, I'll keep GigPerformer's buffer at 256.
From the laptop's 3.5mm out, I'll leave it at 128, no problem. The internal audio is really pretty good with low buffers, and it doesn't sound terrible.
