My understand is that yes, the external displays are both rendered by the CPU and so there are lower frame rates and frames dropped which is a concern of mine since I am pushing this computer to its limits with some applications I run. I've heard that for casual use it isn't too noticeable. Unfortunately I don't think the M1 Air supports TB daisy chaining unless you're ok with mirrored displays. I still can't decide if I want to ask my job for a new computer, a new dock, or new displays lol.
