Lag on view: the video is choppy

Hey folks,

Just hopped on Next after years of rocking Audacity, and I’m really digging it—especially the real-time plugins.

But I’ve hit a snag: the horizontal scroll bar (the main waveform with the vertical line) gets all jerky when I’m playing or recording. No issues with audio latency at all, and my laptop’s handling CPU, disk, and GPU like a champ.

Weird thing is, this doesn’t happen in Sonar or Audacity. I’ve tried bumping up the buffer size, switching from OpenGL to software mode, and cutting back on plugins/processes, but no dice.

Anyone else run into this? Any ideas what’s causing it?

Appreciate the help!

That's an odd one for sure. All I can offer at this point are general troubleshooting suggestions that you may already have tried, but no harm in going over them.

A suggestion: when you're having issues like these, it's always a good idea to post the specs of the system you're running it on. In your case, the make and model of your laptop, amount of memory and HD, whether you're using its internal sound or an external audio interface.

Is the battery in good shape, are you using it plugged in or on battery, and what sort of power plan(s) are you using? I ask because I just last night replaced the battery on my Dell Latitude. On every laptop I've ever done audio work with, their power plans are usually set up to throttle the processor when it's on battery, so I've turned that off and gone with a high performance plan for both cases.

With laptops, as highly integrated as they are, it's always a good idea to check the manufacturer's website to make sure you have the latest drivers installed (especially, in your case, the video driver).
