Low framerate due mostly, possibly entirely on choice of CPU and misunderstanding how multicore CPUs work, and not understanding how X-Plane works. Turbo CPU frequency for your is 3600MHz with 1 or 2 cores only! With 3 or more cores this drops to 3400MHz due to heat dissipation causing CPU throttling. X-Plane uses only 1 core for the flight model and is the greatest single hardware contribution to frame rate. All other aspects of X-Plane and handled by the other cores. Sometimes people look at the core loads and thing that the flight model is multi-threaded but it is not. What they are seeing is the flight model thread being moved from core to core, but the thread is still singular. The movement from core to core is not done by X-Plane, it is done by Windows scheduler and is done to spread heat evenly across all cores to prevent hot spots in the CPU die. I know it's often a difficult concept for many people (including myself) to understand at first but this is the way X-Plane works. The fastest CPU for X-Plane currently made is the i7-4790K, there is nothing faster at this point. Low frame rate not likely with your GPU. And tests done at Anandtech show almost no difference in graphics performance whether GPU card is installed in PCI-e ver. 2.x or ver. 3.x. What does impact graphics performance is whether card is getting 16 PCI lanes, 8 PCI lanes, or 4 PCI lanes- check your manual to see how your motherboard delegates PCI-e lanes for different combinations and slot locations of add-in cards. Cards in SLI usually don't detract from frame rate, they just don't add anything and are costly. Take one video card out and any other cards you have installed for troubleshooting purposes. To try to improve framerate somewhat, turn everything down to minimum settings or off, then turn each one up, one at a time, observe your framerate, turn it back down if eats too many frames. When you find a happy medium between framerate and eye candy and this will be the best you can do with your processor. Bottom line fastest CPU single core speed always wins with X-Plane.

Yes, I had to re-build my Saitek settings after last update.
