paul_nl: I don’t have a PS2 but I tried it with a Gamecube just now and my monitor displayed the 512×480 image just fine with only changing H.active and H.samplerate. Maybe your monitor doesn’t support that low resolution.
I guess so.
Did you try to set 480p in sampler to VESA 640×480 with God of War 480p? That together with 480pX2 upsampler2x: off could give a sharper image if the game is outputting 640 pixels.
I will try that tomorrow.
marqs: Do you know whether 512-column PS2 games use different dot clock than usual 480i games (858 dots per line), or whether PS2 internally scales framebuffer width to usual 640/720 output?
Back in the days I used a TV card to play console games on my PC monitor; that also allowed me to take videos and screenshots in whatever horizontal resolution I wanted. With Final Fantasy XII, using 512 horizontal pixels gave me pixel perfect captures. If the PS2 did internal upscaling, I guess that wouldn’t have been the case.
Also, in contrast to God of War 2, Final Fantasy XII is very crisp in Line4x + upsample2x mode, which again speaks against general upscaling.
