Hi, I am a Computer Technician and I suggest you try to meet the minimums at least or don't waste your money on it until you can meet the min. specs as these types of software are demanding especially on the video card. If you don't meet the specs and are lucky enough to get the simulator to work, it may not accurately help you with your training and flight. But if you wish to try the most common things that happen are below. (These are not the only things but the most probable)

Usually one of two things will happen:

1. It will load and work but be really slow and jittery. Could possibly set all settings as low as possible and maybe get it to work.

2. It will not run at all and you will either need to upgrade your computer, purchase a new computer to meet the specs or try to sell the simulator on a forum or ebay because most places will not return opened software.

Hope this helps.
