oh yeah and GPU didn't matter at all. really nice graphics cards combined with 4GB ram had similar issues to on motherboard GPUs with 4GB ram. We really don't think that the GPU has anything to do with DF in 32x or 64x, that neither was designed to utilize the GPU of a computer system. One person conjectured that the size of the graphics, + the size of the raws, + the size of maps, was hitting the upper 2GB limits on the 32x DF and that was causing it to have to "switch" memory in the ram at a much faster rate then what a small ram was capable of. Add to that the ram needs for the operating system and anything else running and it was just an inevitable failure. once you got to 8GB medium size maps and most mods on had enough room for the DF to get from one end to the other of the data before it gave up. LAA made it be able to buffer more ram at a time so that fixed most of these problems. I had an 8GB system that couldn't do it without LAA and a 16GB and a 32 GB that had no problems(all windows 10 systems), so there was something odd going on there. the bad thing the 16 and 32 had only on motherboard GPUs ... laptops, which generally under performed on most games compared to the old desktop with low memory but better GPU.
