1) In mode 24 bpp, FlightGear ran faster than in 16 bpp (I also switched
the Xfree depth to 24 and 16 then). Is there any known explanation (I
haven't made benchmark, but judging by the eye I thought it was faster)
for this. I think it's the textures fault as they are in 32 bit palette
maybe? (including alpha channel) And FlightGear needs to calculate
approximates to 24 output palette then?
I wonder where the 16 bit dithering overhead comes in? Might this become a
CPU speed (as opposed to interface) issue if there was a lot of texture
swapping going on? I would think that any dithering would be cached...but...
Best,

My suspicions were not correct. I benchmarked the framerate again
yesterday and had 7 FPS in 24bpp mode and 9 FPS in 16bpp mode. I'm
pretty sure the 16bpp mode worked faster in all views and positions in
comparison to 24 bpp.
