It would be simple to write this app., which would be specific to the computer it was run on, provided SimConnect would make available the following variables:
- Readout of the current fps (taken over, say, a couple of seconds).
- The ability to set/read various graphic parameters (e.g. LOD, anti-aliasing, etc).
The user would set a minimum/desired fps goal. An enhancement would allow the user to specify minimum settings and priorities for some of the graphics parameters. She would then start MSFS in a “medium dense” or other “typical” scenery setting .
The program would do a systematic “search” of the graphics parameters, setting them, measuring the fps, setting them to other values, measuring the fps, etc. Such a systematic parameter search is a well known technique in machine learning.
At the end, the app. would suggest the best graphics settings given the user’s fps goal and the “typical” scenery density. It would thus be based on the specifics of the user’s machine and her fps goals.
I have written such an app in other contexts with similar goals.
