Performance Mode is the "default global" settings that the user sets in the GUI. A value of 0 means that it is custom. If you set "High" or Ultra High, and don't touch another slider, you will see Perf Mode be a non zero value.Auto_LOD is a throwback from Combat Flight Sim Pacific, in which the system would automatically "lower detail" to maintain a locked frame rate counter. LOD_Target_FPS is usually a value (80% of the set frame lock) that the system would use to automatically start degrading Level of Detail to maintain the desired frame rate. If the frame rate would drop below LOD_Target_FPS for an extended period of tiem, then the system would compensate by lowering LOD to boost frames.I don't know about the others, but it would be interesting to see what would occur if you locked the slider at say 24FPS, set Auto_LOD to 1 and then see what happens. LOD_Target_FPS should be automatically set to 19 or 20. LOD_Target_FPS can be manually edited, but is overwritten imediately upon setting the FPS lock.
