This is based on what my ram usage tracker has listed from when I used discord about 8 months ago. I'm weird and keep track of ram, CPU, GPU and io usage for every process 24/7.
I haven't used it since switching to fluxer.
It's usage is honestly kinda all over the place. While fluxers is really consistent. Couldn't tell you why.
But I can say that watching video streams would be included in that ram figure.
