Best Microsoft Flight Simulator 2020 settings for the AMD RX 550 (4GB) (2026)

On a AMD RX 550 (4GB) (paired with a balanced Intel Core i5-8600K-class CPU), Microsoft Flight Simulator 2020 runs at roughly 27 FPS at 1080p with our optimized settings — up from about 9FPS with everything maxed. Here's the configuration and what each setting costs.

The AMD RX 550 (4GB) is a entry-level 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 is a real challenge at 1080p — about 27 FPS with FrameCoach's optimized settings, a clear jump from roughly 9 FPS with everything on High.

Across resolutions you can expect around 27 FPS at 1080p and 16 FPS at 1440p, dropping to roughly 9 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.

Resolution	All-High FPS	Optimized FPS
1080p	9	27
1440p	5	16
4K	3	9

💡 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."

BuildingsLow+6% FPS

Autogen building density and detail — matters most low over cities.

Shadow Maps768+6% FPS

Shadow resolution. 1536 looks nearly identical to 2048 from the cockpit.

ReflectionsOff+5% FPS

Water and aircraft reflections. Medium is plenty at altitude.

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.

Terrain ShadowsOff+4% FPS

Shadows cast by mountains and valleys — subtle except at dawn/dusk.

Light ShaftsOff+4% 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+.
