Uneven Scanlines

Post by poopspray »

This has been a problem at least in the last two releases (or two years) of ZSNES for me. It happens on both of my computers (GeForce 440MX and GeForce 6800GT). Here's what I mean by uneven scanlines --

It happens starting at resolutions 800x600 and above -- the image above is at 1024x768. I have fiddled with my graphics cards settings to no avail.

Obviously, the easy fix is to play in a low res or use the nicer filters. I don't mind doing so -- and with my current rig, I can. I just wanted to report this bug if it had not been made apparent by others.[/url]

That's just how uneven scaling works. Mathematicians calls that effect a "moire pattern".

The only way to avoid it is to use even scaling. Thanks to Darkfalz' fix, some modes (640x480, 1280x960) use it to make scanlines look better (at expense of small black bars at the top and bottom).
