I use X-Plane 11 (also used to use version 10) with a 3 monitor setup along with the Logitech yoke, pedals, radio stack, and throttle quadrants. Running on a Linux machine with a Nvidia gtx1070 card, it is plenty smooth and has a great frame rate. Increasing the RAM from 8 GB to 32 last year had a good effect on the sim rate, and even with a 5 year old CPU it works great.
The throttle quadrants (I have two for simulating twins) are a bit touchy and it is tough to set a consistent power setting. I am going to have to see if I can mess with dead zones or if there is some damping setting I am missing.
Overall, I am pleased with the setup. I have had the yoke, pedals, etc. for about 10 years now and they still work fine.
I have a couple of older RV-10 models that were made years ago for older versions of x-plane and they definitely need updating but are decent enough. It would be great to have a professionally made RV-10 model available.
The only thing about X-plane is while they do graphics and visuals very well, the flight models are entirely up to the airplane plugin developer. I was surprised to find that the one Piper Cherokee model I got required significant LEFT rudder on takeoff! Other models suffer from stability problems in pitch but that may also be partly a controls issue.
If you are using a sim for IFR training or currency, I recommend PilotEdge (
