This morning I downloaded the free demo of X-Plane 11 and tried to fly it, but the response to the mouse was so "laggy" that it was unusable. I read the system requirements but really don't know how my system corresponds to the requirements. Here's what my System Information says:
System Type: x64-based PC
Processor: Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz, 2701 Mhz, 2 Core(s), 4 Logical Processor(s)
Installed Physical Memory (RAM): 8.00 GB
Total Physical Memory: 7.87 GB
Available Physical Memory: 4.09 GB
Total Virtual Memory: 9.82 GB
Available Virtual Memory: 5.89 GB
Is that just not sufficient, and would be expected to produce the (non) performance that I found with X-Plane?
