I haven’t noticed instability anywhere else. I’m wondering if slight changes in the clock speed (which the motherboard performs automatically as part of the overall speed and power management) are affecting Premiere’s playback as it seems to jump back a few frames. Some experimentation to do.
Hello,
I’ve had this in CS4 too with full HD video. I read another post for CS2 somewhere, where overclocking was mentioned. If I turn off the overclocking of my CPU, I get an improvement in playback.
