How does a BC PS3 compare to PS1Digital in terms of inp lag?

[Kyusha]

BC: Backwards compatible.

This doesn't really make sense. Input lag refers to how long it takes button presses on the controller to be recognized by the game software. PS1 emulation on the PS3 (All PS3s can emulate PS1 software, not just the handful of early models that can also emulate PS2 software) ostensibly has some degree of input lag (how bad it is, I can't tell), but the PS1 Digital is only on the output end, so it has nothing to do with that.

If we're instead talking display lag, as in the time it takes for an image to be output by the console to being shown on the connected display, I believe neither system adds any perceivable delay to their video output, and that it's entirely dependent on your display.

so ps1 digital wouldnt add lag? how does that work, please elaborate

and thank you

i mentioned bc ps3 because if there would be the same issue once the eventual ps2 digital comes out

I think citrus3000psi might be able to give you a better answer, but I'm pretty sure it's because it doesn't do any time-expensive operations. It might buffer a line or two to facilitate line multiplication operations, but it doesn't buffer whole frames and take a bunch of time to do processing; effectively, it's reading digital video and audio information directly from the board, doubling or quadrupling it, and sending it out to the HDMI TX chip and onto the cable.

Sure, there's delay added in a literal sense, but it's too small to be perceivable or make a tangible difference, even if you were to convert back to analogue for use on a CRT with light guns. Quite similar to what the OSSC does, but with the benefit of having direct access to things not available downstream of analogue video, like the pixel clock.

and ps3 doesnt work the same way? enlight me please

PS3 is an emulator. PS1Digital is a lag free scaler attached to original hardware. Completely different.
