I will 100% do this in the future. It seems that it requires about 50% more processing power but I think it will be worth it. However, I will have to create by hand thousands of examples with precise contour so it will take me some time.
By the way, I had one more quick question:
Is it possible to increase the maximum limit for the "screen latency to correct delay" setting?
In some cases, the current upper bound doesn’t give enough delay for proper sync, especially when working with certain videos or display setups.
