[QUOTE="nyt, post: 562115, member: 98737"] Hm, guess that's a dead end. Even with smooth playback @ 24hz, that still is set to 60. Ok, so I commented out the internals of D3DApp.OnMove, moved the window, and it still fixed the stutter when moving the window, so it doesn't seem to be something inside of MP that's performing wrong, we just need to give something a proper kick after changing the refresh rate. So, in windowed mode, if you minimize and restore in the refresh rate change code, the stutter disappears. This doesn't work for fullscreen though. I stayed up all night messing with this and need to sleep now. I'll try more stuff tomorrow. I'm not a d3d programmer, so someone more familiar with this might know a way to give MP the kick it needs after the refresh rate change without interrupting playback. Can someone try sending EC_DISPLAY_CHANGED to the EVR Presenter? [/QUOTE]
