Best Microsoft Flight Simulator 2020 settings for the Steam Deck (RDNA2 iGPU) (2026)

On a Steam Deck (RDNA2 iGPU) (paired with a balanced Intel Core i5-8600K-class CPU), Microsoft Flight Simulator 2020 runs at roughly 62 FPS at 1080p with our optimized settings — up from about 23FPS with everything maxed. Here's the configuration and what each setting costs.

The Steam Deck (RDNA2 iGPU) is a handheld graphics card with 4GB of VRAM, and Microsoft Flight Simulator 2020 is a demanding, graphically heavy game. Paired with the Intel Core i5-8600K, it runs well at 1080p — about 62 FPS with FrameCoach's optimized settings, a clear jump from roughly 23 FPS with everything on High.

Across resolutions you can expect around 62 FPS at 1080p and 41 FPS at 1440p, dropping to roughly 23 FPS at 4K. With only 4GB of VRAM, keep textures a notch below max in Microsoft Flight Simulator 2020 at higher resolutions to avoid stutter. The biggest free win is FSR 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 FSR (Balanced) — about +55% FPS for a small sharpness trade.
Recommended settings
Upscaling — FSRBalanced+55% 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.
Terrain Level of Detail50+15% FPS
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 CloudsLow+14% FPS
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 Detail50+9% FPS
Draw distance for buildings and scenery objects. Also CPU-bound — lower it together with Terrain LOD if your FPS is "limited by main thread."
Shadow Maps768+6% FPS
Shadow resolution. 1536 looks nearly identical to 2048 from the cockpit.
Glass Cockpit Refresh RateLow+5% FPS
How often the digital cockpit displays redraw. Runs on the CPU — Medium frees main-thread time in glass-cockpit airliners with no real downside.
BuildingsMedium+3% FPS
Autogen building density and detail — matters most low over cities.
ReflectionsLow+2% FPS
Water and aircraft reflections. Medium is plenty at altitude.
Terrain Shadows128+2% FPS
Shadows cast by mountains and valleys — subtle except at dawn/dusk.
Light ShaftsLow+2% FPS
God-rays through clouds. Pretty at sunset, cheap to lower the rest of the time.
Texture ResolutionUltra-1% FPS
Ground and aircraft texture sharpness. Needs VRAM more than GPU power — Ultra wants 10GB+.
