It is pointless to post a 5 minutes video explaining the idea, that can be laid down in 5-7 words.
Besides, any kind of suggestion should be backed up with something other than personal experience.
- Do you happen to know any shipped titles, confirmed to utilize this method?
If above is no,
- Can you reference to a publication with above-mentioned method?
If above is no,
- Do you have some sort of reliable metrics to prove that suggestion is viable?
If above is no, you should go back to the drawing board and think of something better.
I state that from everything discussed in the thread, your suggestion delivers least performance gain while giving back the most noticeable visual deterioration.
