Okay, think I have a really good Wii setup in terms of visual quality, the best I've managed on an HD display.
Running Wii Component to the OSSC and then into the USB3HDCAP connected to my PC. Using AmarecTV, I set res to 1440 x 960p and a borderless window at 100% scale in the middle of the desktop. This maintains the 960p integer scale of line-doubled Wii output and keeps even scanlines. The empty space around the window isn't bad on a 1080p panel, just like the output of modded HDMI consoles. For now I manually set a dark desktop but it would be nice to figure out how to add a black background with Amarec to cover my desktop (full screen mode resizes the video feed and breaks the 960p integer scale).
Setting Analog Sync LPF to 10MHz (medium filtering) removes the Wii's blurring (at least in some games I tested). When it works it reminds me of the UltraHDMI N64's de-blur. Guilty Gear looks perfect from what I can tell. Will post screencaps later.
that sounds pretty good. i'm tempted to try that since i already have a lot of that ready.
how's amarec's input lag in this setup?
