I was experiencing an intermittent frame glitch, where every 3-5 seconds I’d get a 0.2-0.5s pause in rendering.
This would often be reported as ML (mainloop) limited in the PerfMeter.
- An empty patch with just a Renderer and PerfMeter
- DX11 and DX9
- Switching to another computer with AMD instead of NVidia
- Different versions of VVVV
Nothing made it go away
Then I realised I’d had issues recently between Chrome and Visual Studio Code. (Having them open at the same time often caused one to lock up. Presume because they both use chrome for rendering, and chrome uses some funny tech for dealing with GPU).
Anyway. Quit all chrome.exe’s in the Task Manager, and voila!
No frame glitches!
Is this a known thing?
