Hi there. I have a problem with the Internet when I use After Effects. The problem is very slow UPLOAD speed (about 0.10-20mb/sec and slow down DOWNLOAD speed deteriorating by about 2 times.
But i noticed that if I close After Effect, my Internet becomes normal in most cases
My guess is that After Effects, Media Encoder AND your browser are all using your graphics card for acceleration - so when you use AME for rendering, it is hogging all the GPU's resources meaning your browser slows down.
