Hello, I was wondering how much video memory Chimera is capable of accessing.  I currently have a 898Mb videocard that begins to slow down with a 550x550x550 map (at step size 1).  This map is actually a downsample of the true 1100x1100x1100 map coming in at 5GB.  I was contemplating going for a much larger video card at 4GB, however I was curious to what extent I could expect to see acceleration using Chimera with such a massive dataset (600+MB) and video card.

Thank you,
