36 He111H's (4 groups of 9) intercepted by 12 Spitfire MkI's (2 groups of 6)
 

I created this mission in the FMB and ran it.. worked very well so I DL'd fraps.. the FPS with FRAPS are actually a little lower than they were without it..and the video ends right before my awesome guns pass <G> But you'll get the idea..

Resolution is 1920X1200 grass OFF, Filter OFF, roads OFF, building settings to lowest possible, both detail and number All other settings are HIGH

Alt is about 5500-6500M and when we flew over land the fps did not grop below the 29/30 bracket..

Watch it on you turb. full screen to get the idea.. the bombers are a little hard to see initially..they are stacked at 5500 6000 6500 and 5500 again.. all are visible as the video ends..

Why did you only show such a brief video?

because that's the amount of time you can capture with a free version of Fraps.

Sorry about the short video, its the free version of FRAPS and it just shot off.. I'm uploading another that I started recording AFTER the attack so it shows more of the combat and chaos...

Oh :)
