Absolutely… but the Devs completely missed this point and created a “Low Power Mode”. I’m not kidding. Wouldn’t believe it if I hadn’t seen it for myself in the Live Dev Q&A from May 25th:

Live Dev Q&A - May 25th, 2022 - Community / News and Announcements - Microsoft Flight Simulator Forums

Note: that link will take you to a post containing a link to the video as well as a complete, written transcript of the entire Live Dev Q&A! Thanks so much to Moderator @N316TS for tackling the tedious job of transcribing the entire session!!! So much information would be lost if we only had video. Greatly appreciated!
