Hi Guys,

A strange one for you - and not something I've noticed before, it could well be that it's always been like that, but I don't have any other systems to test.

Basically if I open vMix with 0 inputs, then resizing and moving the vMix window works exactly as you would imagine.

Once I get to around 20-30 inputs open - when I drag the vMix window around the screen, the movement appears to be super sluggish and can sometimes take a few moments to catch up to my mouse. Doesn't seem to matter what I have in the inputs, even 30 x PNG or JPG images and still the issue persists.

GPU and CPU percentages are all sub 30% when moving the window - even task manager in windows reports fairly low usage.

GPU is GTX1080
CPU is i7-6700k
RAM is 32GB

Would you guys be able to tell me if this is a common thing ?

Thanks
