I too have 2 Gigabyte VRAM. Here is a short clip with some HUD graphs:

It's pretty clear that the stutters correlate with activity in "num bytes

I have also tried the native borderlands 2 for a few minutes today and I'm
seeing similar stuttering. It doesn't happen quite so often, but it's still
often enough to be an issue.
