Legend 👏
Glad you are following this development

Thank you Bilal, you are a wizard! Realtime preview without global draw it's crasy. You gave a big boost with sd overclock and now realtime preview!
You're welcome! , Thanks, I thought enhanced sd_uhs and real-time correct preview is the two last thing we could get on DIGIC 5 Canon cameras, a new ML decade has started for newer cameras, I don't think any of main Developers would work on DIGIC 5 cameras again, just a thought . .
Will it be possible to have good ratio for 1×3 mode too? Porting on EOS m should be easy but on 5diii and 5dii more work to do.
For 1x3 mode In theory it's possible, but more knowledge is required, I am working on it, EOS M shares identical registers and values, I sent same preset to @Danne and Confirmed it's working, 5D3 have different set of registers, it might be easy to port if we the effects of registers were the same, I don't have the camera I can't work on it, Sorry . . 5D2 is another story, and might be simpler.
How can I test this on the 5DIII ?
I have firmware 1.13 and I can compile ML myself, at least for 5DIII. Is there a repo somewhere where I can download a file, or did you just go with atgd gui ?
Well, all said: is there something implemented already ?
There is nothing for 5D3, Sorry, No one has worked on it yet, I can't work on it too because I don't have the camera.
Anything working on eos m? I think this is what I’ve been dreaming about for like 2 years... it’s real live view in real time right? The choppy preview live view that shows the framing is all we have now. Or real live view with the wrong framing. If this is real live view with correct framing you’ll be the hero of all time:)
Already working on EOS M, no available build yet, It's Real-Time Correct Framing, real-time as Canon Preview, correct Framing as ML Framing, both in one, you are welcome.
This is so exciting! Keep experimenting please!!!!
And it gets more and more exciting
