Re: “There must be guideline requirements… it doesn’t have to be official”
Alan, I hear you — you’re basically asking “give me a ballpark so I know if I’m wasting my time.” The problem is that once I post a made-up “min/recommended/max” table (even with a big disclaimer), it gets repeated as fact and people start spending real money off it. I’ve watched that happen too many times on these forums.
What I can do (and it’s actually more useful for MSFS than a generic spec list) is give you a practical guideline for what decides whether you keep “MAX/Ultra” in a new MSFS generation, and how to sanity-check your i9/3090 against it.
1) What “MAX” is usually limited by in MSFS
In MSFS 2020 (and almost certainly 2024), the “Ultra/Max” preset is not the whole story. The sim typically hits a wall in one of these areas:
- CPU main thread (the #1 reason “MAX” doesn’t feel max)
- big airports, dense photogrammetry, glass cockpit aircraft, lots of AI/ground traffic
- GPU + VRAM
- 4K, high render scaling, heavy clouds/overcast, ultra textures
- RAM + storage
- smoothness/stutters, scenery streaming, long pauses (SSD/NVMe matters here)
Your 3090 FE is still a beast on the GPU/VRAM side. So the deciding factor for “same MAX as 2020” is usually: which exact i9, what resolution you run, and how aggressive your LOD/traffic sliders are.
2) A “guideline tier” that won’t pretend to be an official spec sheet
This isn’t a requirements chart — it’s the way I’d sanity-check a rig for “high/ultra” expectations in a modern MSFS-style sim:
- For high/ultra at 1080p or 1440p
- strong modern i7/i9 or Ryzen 7-class CPU
- 32GB RAM
- SSD/NVMe install
- upper-mid to high-end GPU
- For ultra at 4K
- top-tier GPU (your 3090 is in this bracket)
- plus a CPU with strong single-core/main-thread performance
- 32GB+ RAM
- For “maxed LOD + heavy traffic at big hubs”
- even high-end rigs often need to trim Terrain LOD/Object LOD and/or traffic a notch for smoothness
So: you’re already “good on GPU.” Whether you keep “MAX everywhere” depends mainly on the CPU generation and your “MAX” sliders (LOD + traffic + resolution).
3) If you want the quickest real answer: tell me these 4 things
If you post the following, I can give you a straight “yes, likely / yes, but with caveats / you’ll probably need to tune X” based on how MSFS actually behaves:
- Exact i9 model (example: i9-9900K vs i9-10900K vs i9-12900K etc.)
- RAM amount (32GB/64GB) and whether the sim is on SSD or NVMe
- Your resolution (1080p/1440p/4K) and whether you use VR
- In MSFS 2020: your Terrain LOD + Object LOD values, and typical FPS at a busy airport
If you can, also tell me what you consider “flawless” (locked 60? 40? “no stutters”?), because that changes what “same max settings” really means in practice.
