Hmm. I never used the NTSC filter on bsnes before. Here's what I've done to try and recreate that.
Video Mode: Scale MAX; NTSC; Fullscreen; Correct Aspect Ratio.
Video Filter: NTSC. In configure: Everything is defaulted to RF, including no merging fields. Smooth video output is on. Emulation Speed is set to 100%. And I'm using a Xbox 360 pad, wireless.
As for hardware, I have an AMD Phenom II X2 550, clocked as shipped to 3.1 GHz. ATI Radeon HD 2600, 4GB of RAM, and Windows 7 64-bit.
If I have 'sync video' and 'sync audio' both checked, I do indeed get some strange, occasional, stuttering - where the FPS in the bottom corner drops from 59/60 fps to about 53 fps. Then it's fine. Now if I turn off sync audio, the fps never drops below 59 fps -- but the sound still stutters now and again. And when you get an item in game, the audio queue sounds TERRIBLE... unless you sync audio.
In other words, I've recreated your issue using bsnes v0.054. I never noticed it before. In writing this I noticed v0.055 was out and tried it again real quick.
What I noticed was Smooth Video Output doesn't do anything anymore; like it's enabled all the time. But now the video 'glitches' like it's having trouble keeping that particular filter turned on - going 'sharper' for half a second at at time. And again, the glitches were terrible if I had audio sync on - but if I turned that off, no stuttering... but the audio was scratchy as hell.
Very weird.
