Question / Help Preview Screen Stutter (snes9x)

Hello,

I've been looking for a bit of a solution with stuttering that occurs within the preview window while using snes9x 1.41.

Basically, the situation is as follows:

When the initial capture begins (Game, Window, or Display) the frame rate within the preview window is buttery smooth. Perfect for broadcasting a nice smooth experience. However, over a period of time (3 to 5 minutes) depending on method, the preview screen will then begin to stutter. Game capture will stutter within 30 seconds, Window Capture 3-5 and, Display Capture seems to last the longest, at about 5 before the stutter rears it's head.

When this happens, sometime the stutter happening will self-clear after a minute or two (or even a scene change), and a few minutes later, starts to happen again. It can be light, or rough stutter. Sometimes it's an occasional "bump" that lasts a few seconds, and others, it's almost looks like 30fps instead of 60 for up to a minute.

What's even more baffling, is that changing focus on the window (say, pressing ESC to bring up the menu bar from full screen) -- immediately resolves the stutter to begin the loop above anew.

It's driving me nuts in resolve as it reflects on screen. It just shouldn't be happening from my perspective. The last thread I could find on snes9x with this issue, was to use full capture of a monitor. I proceeded to move from Win 7 to 8.1 for this purpose. That helped with allowing display capture, but not the stutter issue itself as it would happen still in display capture (just longer to show up). I also upgraded to an SSD, did full reinstall, thinking maybe it was an i/o problem on the HDD, again, to no resolve.

The CPU is a i7-2600k overclocked @ 4.4ghz, Asus p8z67-v, and 16 vengeance gb ram (also OC'ed), and GeForce 560ti x2 in SLI. SLI on or off still results in the same behavior. Broadcasting on or off still results in the same behavior.

Nothing in the system is saying it is over stressed, as running OBS and Snes9x @ 6xbrz reaches ~ 33% CPU at most. Changing settings within Snes9x does nothing, as the stutter will still occur eventually. Processor affinity doesn't impact length of how or when the stutter occurs, or how or when either, even if I give OBS 7 cores and Snes9x.

Any recommended solutions to try would be most welcome.

Thank you!
