Yes. Save it, then re-open the sim and the altered preference(s) should now apply.

Found a solution, which does not require the user to update the graphics processor! Follow this simple process: 1. Go to your X-Plane 10 Folder 2. Access the 'Aircraft' folder 3. Enter the 'X-Aviation' folder 4. Enter the ''IXEG 737 Classic' folder 5. Scroll down and open the 'IXEG_user_prefs' text document 6. Within those preferences, you can alter settings that you couldn't have previously adjusted in the sim, by simply changing the '= number' alongside that command, e.g., 'steam gauges=0' is the default setting, however, if you change that to 'steam gauges=1', and save those preferences, the next time you open X-Plane, the steam gauges will appear in place of the modernised centre instrument panel. NOTE: For this to work, you must re-open X-PLANE subsequent to adjusting these settings.
