In ZSNES emulator a super nintendo emulator is Triple buffering concidered a filter?

I noticed triple buffering in ZSNES emulator that it kind of makes the image a tad bit blurry. Though it is not under filters should I enable it or is having just video sync better? Video sync in ZSNES makes everything smooth and blocky. Should I just enable video sync and not triple buffer? I want it to look as close as a SNES super Nintendo graphics as possible.
