Their GPU has three times the GPU cores I'm using too! The quadro has 1536 cores vs my AMD's 490 and it also has full PCI-E bandwidth, the apple GPU integration only has a couple of PCI-E express channels!
I've been doing some work on the Lanczos - specifically around upscaling into images as little as 60x60 pixels in association drizzling. I'll need to re-optimise after but it's still going fast enough

I've been dogfooding today - plenty of thoughts and ideas, however the testing of the focusing seems to be doing a good job. The green dots are the frame quality, the band of green marks the band between highest and lowest grades. Bottom is 0%, top being 100% fine detail - so in theory it will never get there
This was shot through the conservatory roof - the weather outside was very bad this morning and is still exceptionally windy (UK had national weather warning for heavy rain and winds!):

I have a couple more ideas on this - such as exposure adjustment to maximise detail - also I like the HDR idea however for now I need to get some heavy testing done as it works but not completely to my satisfaction (I had difficult conditions with clouds!).
Cropped screenshot - showing higher quality grading during a downpour (this was through the rain soaked conservatory window) - the titan is only 659x495 pixels:

Not bad.. so I may add gradient histograph too - but for now.. that works. Time to look at the app and get things tested to destruction - just waiting for the sun set - it's meant to be clear tonight
