[QUOTE="nyt, post: 561999, member: 98737"] Either way, the refresh rate was still being set properly. I just thought this was interesting behavior so I took a stab at it. I don't know how to do this, however, I do not believe it to be a bug, but either way, it is indicative that it is trying to sync to the wrong rate. When the stutter is not there, it is always at 24fps, however, when the stutter is there, depending on system load, it will generally be ~60, sometimes lower, but always above 24, and never above 60. I'm a programmer by trade, but I've never done D3D programming, so this is taking me a lot longer than someone else who is familiar with all this code. It's not a problem exactly with the refresh rate changer, it's doing what its supposed to. The whole directshow/renderer part of the code just doesn't know the refresh rate has changed. It will take me quite a bit of time digging for where this all is since this is all new to me. It seems to be when the directx stuff is setup, that's the refresh rate that it uses unless it's updated. Simply changing the refresh rate does not help. DX needs to know the refresh rate as well. Still working on this. Hopefully I can get this resolved soon =] [/QUOTE]
