Best Microsoft Flight Simulator 2020 settings for the NVIDIA RTX 3090 Ti (2026)

On a NVIDIA RTX 3090 Ti (paired with a balanced Intel Core i9-12900F-class CPU), Microsoft Flight Simulator 2020 runs at roughly 73 FPS at 4K with our optimized settings — up from about 54FPS with everything maxed. Here's the configuration and what each setting costs.

The NVIDIA RTX 3090 Ti is a high-end graphics card with 24GB of VRAM, and Microsoft Flight Simulator 2020 is a demanding, graphically heavy game. Paired with the Intel Core i9-12900F, it runs well at 4K — about 73 FPS with FrameCoach's optimized settings, a clear jump from roughly 54 FPS with everything on High.

Across resolutions you can expect around 131 FPS at 1080p and 95 FPS at 1440p, dropping to roughly 73 FPS at 4K. Its 24GB of VRAM is plenty for Microsoft Flight Simulator 2020, so textures can stay maxed. The biggest free win is DLSS upscaling — set it to Quality for a large FPS boost at little visual cost.

💡 Microsoft Flight Simulator 2020: Often limited by the CPU main thread over cities - Terrain/Objects LOD are the real levers there, Volumetric Clouds the big GPU one.
🚀 Biggest free win: enable DLSS (Quality) — about +35% FPS for a small sharpness trade.
Recommended settings
Upscaling — DLSSQuality+35% FPS
MSFS supports DLSS and FSR (plus a Render Scaling slider). Big GPU savings — though note the sim is often limited by its main CPU thread, where upscaling doesn’t help.
Texture ResolutionUltra-1% FPS
Ground and aircraft texture sharpness. Needs VRAM more than GPU power — Ultra wants 10GB+.
Terrain Level of Detail100baseline
The most important setting in the sim — how far detailed terrain streams in. It loads the CPU’s main thread heavily; 100 is the sweet spot, 200 is for top-end CPUs only.
Volumetric CloudsHighbaseline
The heaviest pure-GPU setting. Ultra clouds look spectacular but can cost 20%+ FPS in overcast weather — High is the sweet spot.
Objects Level of Detail100baseline
Draw distance for buildings and scenery objects. Also CPU-bound — lower it together with Terrain LOD if your FPS is "limited by main thread."
BuildingsHighbaseline
Autogen building density and detail — matters most low over cities.
Shadow Maps1536baseline
Shadow resolution. 1536 looks nearly identical to 2048 from the cockpit.
Terrain Shadows256baseline
Shadows cast by mountains and valleys — subtle except at dawn/dusk.
ReflectionsMediumbaseline
Water and aircraft reflections. Medium is plenty at altitude.
Light ShaftsMediumbaseline
God-rays through clouds. Pretty at sunset, cheap to lower the rest of the time.
Glass Cockpit Refresh RateMediumbaseline
How often the digital cockpit displays redraw. Runs on the CPU — Medium frees main-thread time in glass-cockpit airliners with no real downside.
