What I mean by looking good is hiding game artifacts and jagged edges. I look around in youtube for Framemeister+ps2 3d games scanlines enable and it did hide some games artifacts and jagged edges look less noticeable. I guessing that OSSC will be similar with Scanlines enable. I look around OSSC in google and I did not find pictures or videos of OSSC with 3d games. It would surely help people who want to buy it. I found this video that shows how Framemeister+wii looks with scanlines skip to 3:53 minutes in the video https://www.youtube.com/watch?v=E4jix0d_VDU . I would hope that ps2 looks similar with OSSC+scanlines?
In regarding to ps2 emulation for it to be full speed playable it needs a much more powerful PC cpu than in dolphin emulation. That’s why I have slowdowns with it and it is much smoother with dolphin.
