Some work some don't

I asked before what video card you have and other computer facts..
You chose not to answer so how can we help if we don't know what we are dealing with and only you know.

AMD Radeon HD8400...

Thank you

The only way around it is to lower or shut off some of the non essential slides.
Some aircraft are very graphic intensive and for that card to render them and have good ground graphics is too difficult.
It chooses to render the ground and not the aircraft.
Some will work, others not.
Not much you can do with an integrated card unless you have an empty slot on the motherboard for a new card to take over and do away with the integrated one.
If it's a Dell the chances are slim.

thanks!!

Well it looks like I need a better graphics card.. but I just don't understand why some developers planes work and others don't.. The piaggio is a huge file and it works fine with my graphics card.. There has to be something unique about some of the other creators files... Just my feeling....

Different programs are used to make an aircraft.
Some are more graphic intensive than other.
The stronger the card the easier time it has rendering it on your Sim.

You have to have an empty slot that can accept a new video card that will take over the integrated card.

Check the inside of your computer to see if you have one.
If you've never opened the computer before, don't touch anything, static electricity from your hand can burn out the computer.
