I just went and rewatched the MSFSOfficial September 2024 Developer Stream, where they explain the system requirements for PC (Technical Q&A chapter starting at the 19 minute mark)
Although not mention in the written specs, Seb and Martial explain how the 3 levels are for a single monitor, and aim to achieve 30 FPS!
| Spec | Minimum | Recommended | Ideal |
|---|---|---|---|
| VRAM | 4 GB | 8 GB | 12 GB |
| RAM | 16 GB | 32 GB | 64 GB |
| Screens | 1 | 1 | 1 |
| Resolution | 1080 | 2K | 4K |
| FPS | 30 FPS | 30 FPS | 30 FPS |
Seb says that he is running 32 GB and you only need 64 if you run everything Ultra and have other things running, recording, etc… (ha). It’s clear they did not contemplate mutliple monitors. I’ve just submitted a Wishlist item to add recommended specs for multiple monitors to the official FAQ / Specs page, hopefully this will help bring attention to supporting triple screens.
