<![CDATA[Unexpected bad performance]]>Hi all!

I made a live gig with a patch and it went really smooth during the whole performance. During preparations the cpu load was about 35%.

Now, a few weeks later, the performance is much worse, even on the same unedited save files. I don't get what could be wrong.

Appearance: Annoying stutters every 10 seconds

CPU load: 60-70%

Framerate:  about 24-27 (frame rate goal 30fps)

VPO: 150-179

Cycles: 0.70

The patch consists of many GLSL shaders, some feedback looping and a few virtual projectors. All other applications are closed.

Anyone want to take a shot at guessing what could have happened?

Can you send the patch either here (if you're comfortable) or in a support ticket (see the link in my signature) so we can take a look at it? In medical terms, it can be hard to diagnose a patient over the phone rather than through a physical exam.

Is it possible you are low on drive space?
