Hello, i don't know if it's supposed to work that way for such a light "workload".
After this new Steam update and the "point shop" addition i noticed a stutter and then a massive frame drop in the store, being pretty annoying to browse like it was running at 20 fps, and having a high refresh rate monitor turns this issue a bit more irritating, normalizes on certain occasions but it is very inconsistent. Checking the Task Manager i saw a big video encode spike usage. I am attaching a short video to exemplify the situation.
