Paul,
I did a complete UNinstall and then a reinstall...no problem as that still SAVES your flights, aircraft and scenery installations.
However, it does overwrite your old FS2002.cfg file.....hence that is the reason I had the question in this forum about how to enter the OLDMODULES entry into my new .cfg file.
I have found that the default selections of Medium or High for the Scenery sliders produces a better result than does a Custom slider arrangement....for frame rates and actual scenery clarity.....however you do have to select TriLinear functions manually.
I use the HIGH Scenery setting and Extreme Dense Scenery...and while I could use a higher frame rate speed...I use 30 fps...and FS2002 rarely dips below the 28fps range while flying.
The 30 fps setting really allows my server computer to "feed" 4 other computers that are running Project Magenta, FlightMax and Airplan....along with 18 USB inputs for GoFlight, Aerosoft MCP747 and the PFC center console hardware.
Regards,
Mel
