Hi, I have just upgraded from X-plane 9 to X-plane 11 and am having trouble with low frame rates. |Getting 5 - 9 fps (with absolutely everything turned off or to minimums) typically and so very delayed flight time. The only deficiency of my system against your requirements spec is I only have 4GB RAM. processor is a 4 core i3. Question is, if I upgrade the RAM is that likely to fix the issue or is this machine not really up to it. I am trying to fly GA planes (eg the Cessna 172) for instrument flight practice, so scenery rendering is not an issue but the slow flight time is.
