I clearly understand that computer should do the processing, not the camera. But there might be something that could be done in-camera to improve image quality (such as "dark frame", "bias frame", maybe something else). Reduced FPS of 1D X for high ISO gave me the idea Canon might be using this technology in the camera.
Reduced FPS at very high ISOs may simply be because high ISO leads to noiser files which leads to lower compression ratios which leads to more data per frame => lower throughput.
I'm not familiar with the logic of A&D conversion, so correct me if I'm wrong.
It seems that more processing power is required for complex textures. From my experience scenes with lots of leaves on trees might be more capacity-consuming than other shots I normally take. More capacity required for a file could mean that more data should have been processed and more processing power required.
Interesting to see whether FPS depends on scene you're capturing, so we can identify whether complex textures affect FPS or some additional technique is applied to reduce noise in 1D X. Would be great if someone else can share his thoughts on this too.P.S. Sorry for off topic
