This is not at all stretching it. Discord's client is very poorly optimized and bloated and it is known since a long time. I could never run it on my hardware with a comfortable experience. Even some of my friends would ask me to look for and provide them older versions of the app because each update would make it laggier for them to use. I don't live in a First or Second world country with a good paying job. Most electronics are imported here and cost a lot.
