1) direct RGB 0 lag its the reference actually ... 2) i wouldnt know i dont have it but i assume its close to 0 or around 10 really dont know? on low lag RGB2RTG does 7-9 at the top of the picture 10-14 at the bottom more or less. Turning it off gives you 23-33ms . Emulators tho interestingly give you 40-100ms for sure so you'd feel that
Look "Sharp" is already bilinear =>Each HDMI pixel takes the amiga pixels it covers, in proportion, so only the columns and rows where a pixel edge falls get mixed on another note "Smooth" is unicam.resource’s cubic filter (Mitchell-Netravali type), on|off, the same for both directions. Scanlines: are well past Indivision’s: 1% steps, six shapes, separate NTSC and interlace strengths, and Integer (exact) for whole factors not to advertise here. So if we would implement this it would look like “Softness across” and “Softness down”, 0 to 100% slider type of thing, only problem is will the pi's gpu eat it :)? i think it will we'll see. I will look into it thanks for the suggestion!
