The settings that I use inside of the simulator can vary
depending on the type of flight I am doing. Generally, I have different
settings for each scenario. For example, in heavy weather and scenery
scenarios, I will generally tend to tone things down a little on the sim
sliders to gain better performance.
As a general guide, you can see the basic settings that I use in the simulator for most situations. I find that these settings give a good balance between visual quality and sim performance.
Please note, your system will be completely different to mine, and as such, you might need to adjust your settings even further to suit the limitations of your machine.
