Not recently but yep, ED loves VRAM (and CPU).
Playing in 4k with DLDSR x2.25 (so 5760px resolution, which is the only effective way to get rid of the aliasing).
I am seeing 18GB (total, including about 2 GB for Windows) and noticed a couple of time that it did max out the 24GB of my RTX4090.
Even today, sitting in front of an on-foot terminal at a station (waiting for the mission board to refresh), I was super high in VRAM and GPU running almost constantly at 90-100% frequency, even reached max 87 degrees Celsius.
But guilty, DLDSR does not help
As for stuttering, it happens frequently but it seems related to communication with the FDev servers, since I have not observed any bottleneck when this occurs.
