I'm having trouble with PD (vanilla, fresh install, no external yet) on my new pc. Everything happening in the canvas (creating objects, typing values in the boxes, drawing connections between inlets/outlets) is excruciatingly slow - I'm talking about like .3 - .5 second delays, and very stuttery. It took me a full minute to create an [osc~] object and connecting it to a [dac~] to test the audio - which seems to work fine. The rest of the GUI (the panels, the menus) work fine.
It's quite frustrating and having googled the issue without finding anything useful. I tried switching from my pc's integrated graphics card to the NVIDIA one back and forth for the executables in the /bin/ folder, without success.
My pc is an Asus ROG laptop running MS Windows 10 (Home)
Processor: Intel(R) Core(TM) i5-6300HQ CPU @ 2.30GHz, 2304 Mhz, 4 Core(s), 4 Logical Processor(s)
Display: Intel(R) HD Graphics 530 RAM : 8.00 GB
Edit: I installed Purr Data and have having the exact same problem with it, which I find very weird since Purr Data doesn't use Tcl/Tk to display the graphics,.. I'm very confused.
