Here is a link to a potentially very useful video by flightsim YouTube blogger Q8Pilot.
This is a video of 7 ways to improve your frame rate.
Not all his settings will necessarily apply to your setup, but it is worth watching his video, comparing his settings to yours, and listening to his reasons for applying certain values and switches.
Of course, when the next major X-Plane 12 update is released, some of these settings may be outdated (The video was released in September 2026), but that’s the reality of our ever-improving X-Plane 12. 😁
Please do not consider this a “one video fixes all” solution. No flight sim computer system is identical to another. Some of his ideas will not affect your system, or may even result in worse performance, but overall, this video is full of useful settings that are worth a look. Use what works and ignore what doesn’t.
If your system works fairly well, but you are looking for some tweaks to coax just that little bit more performance, make sure you make a note of your original settings before making alterations. I personally have to admit being very guilty of this mistake – you will never reliably remember what your original settings were after tweaking things a number of times. Ideally, simply make a second copy of your entire X-Plane 12 folder before making any changes. Ignore this paragraph at your peril!
