All sketches heavily stuttering every 5-10 seconds


#1

I have no idea what’s causing this, it doesn’t have anything to do with the code. Even the demo sketches are affected in exactly the same way. I’ve tried a clean java install and increasing available memory to 1024MB in the PDE, but that had no effect at all. My system should be able to handle these sketches without breaking a sweat, and has done so on in the past on the same version (3.4).

Does anyone know what could be causing this kind of behaviour? I’d really like a second opinion before resorting to a full system wipe.

What OS do you run?
What are your system specs?

Windows 10 64bit
AMD PhenomII X4 970
AMD Radeon R9 270X
8GB DDR3

Brainstorm:

Have you inspected your current processes with process utilities? Hopefully you don’t have bitcoin miner malware installed, but something else could be hitting your processor hard every few seconds – a syncing utility that has hung up, like Drive or Dropbox, video streaming, a hung Chrome tab running the background, etc…

Are you running an antivirus program? Does temporarily enabling / disabling it change the stuttering? If you reboot and run Processing without launching any other applications, does it stutter?

Thanks for the help, but I’ve already tried all of that. No malicious processes running, the sketch still stutters running on a fresh boot, and antivirus doesn’t make a difference.

The weird thing is that it’s just processing that’s stuttering, nothing else. My C++ port of the sketch, resource intensive games, and even other java applications are running just fine. I’ve already done a clean install of both java and processing, but to no avail.

Is it a P2D / P3D sketch – that is, OpenGL? If so, you could try running a processing-intensive JAVA2D sketch to see if you get the same stuttering – that might narrow it down to something about Processing and the graphics card.

Edit – oh, I just saw you said demo sketches are similarly affected. Including all renderer types?

as far as i can tell the stutter is exclusive to 2d rendering. 3d demos like moveEye are running fine but my 2d sketch and very basic demos like mouse2d are stuttering.
