quick question: Minimum requirements WOFF vs. ROF

[Fielder 3,669]

The latest editions of Wings over Flanders Fields...... vs. ......Rise of Flight.

 

My question is in general, which one of these two World War I combat sims is easier to run without stutters on a system that runs FSX at 15 to 25 FPS (FSX runing stock scenery files with most FSX graphics enhancements turned on, but not using 3rd party airports and such).

 

Thank you.
