Texture Resolution Explained
Estimated Lesson Time: 30–40 Minutes
Lesson Overview
So far, we’ve covered several of the most important graphics settings in Microsoft Flight Simulator, including Display Settings, Anti-Aliasing, Frame Generation, Render Scaling, Terrain Level of Detail and Object Level of Detail.
In this lesson, we’re going to focus on Texture Resolution.
Texture Resolution is responsible for the detail you see on almost every surface in the simulator.
It affects:
- Aircraft paint
- Cockpit panels
- Runways
- Taxiways
- Buildings
- Ground textures
- Mountains
- Roads
- Vegetation
- Airport signage
Many users assume that setting Texture Resolution to Ultra will automatically reduce FPS.
In reality, Texture Resolution mainly affects VRAM usage, not the overall processing power of your GPU.
Understanding this setting will help you make informed decisions based on your graphics card and available video memory.
Lesson Objectives
By the end of this lesson you will understand:
What Texture Resolution is.
What VRAM is.
How texture streaming works.
How Texture Resolution affects image quality.
How it affects GPU memory usage.
When Ultra Texture Resolution is worthwhile.
When High is a better option.
How to choose the best setting for your own graphics card.
1. What Is Texture Resolution?
Every object in Microsoft Flight Simulator is covered with a texture.
A texture is simply an image wrapped around a 3D model.
Examples include:
Aircraft paint.
Cockpit labels.
Runway markings.
Taxiway signs.
Buildings.
Road surfaces.
Grass.
Mountains.
Cloud textures.
Without textures…
Everything would appear as plain shapes with no detail.
Texture Resolution determines how detailed those images are.
Think Of It Like Wrapping Paper
Imagine wrapping a gift.
One wrapping paper is low quality and blurry.
The other is printed in very high resolution.
Both wrap the same box.
But one looks much sharper.
Texture Resolution works exactly the same way.
The object itself doesn’t change.
Only the quality of the image covering it.
2. What Is VRAM?
VRAM stands for:
Video Random Access Memory.
Unlike your system RAM…
VRAM belongs to your graphics card.
Its job is to store graphics data that the GPU needs immediate access to.
Examples include:
Textures.
Shadows.
Frame buffers.
Lighting data.
Geometry information.
Render targets.
The more detailed the textures…
The more VRAM they require.
VRAM Analogy
Imagine your GPU is a chef.
VRAM is the worktop.
The larger the worktop…
The more ingredients the chef can keep close by.
If the worktop becomes full…
The chef has to keep walking back to the pantry.
That slows everything down.
The same thing happens when VRAM becomes full.
The GPU has to fetch data from slower system memory.
This can introduce stutters and reduce overall smoothness.
3. Texture Streaming
Modern games do not load every texture into VRAM all at once.
Instead, they use texture streaming.
Texture streaming loads textures as they are needed.
For example:
During taxi…
The simulator loads airport textures.
During climb…
It loads surrounding terrain.
Approaching a city…
It streams city textures.
Flying over mountains…
It streams mountain textures.
This keeps VRAM usage more efficient.
Why Texture Streaming Matters
If texture streaming cannot keep up…
You may notice:
Blurry textures.
Delayed loading.
Textures suddenly becoming sharper.
Pop-in.
Momentary stutters.
Storage speed and internet connection (for streamed scenery) can also influence how quickly textures become available.
4. Texture Quality
Microsoft Flight Simulator usually provides several Texture Resolution options.
Examples include:
Low.
Medium.
High.
Ultra.
Each setting changes the resolution of the textures stored in VRAM.
Low
Lowest VRAM usage.
Lowest image quality.
Blurry cockpit labels.
Soft runway markings.
Useful for entry-level systems.
Medium
Improved quality.
Moderate VRAM usage.
Suitable for lower-mid range systems.
High
Excellent balance.
Sharp cockpit displays.
Good airport textures.
Moderate VRAM usage.
Recommended for many systems.
Ultra
Maximum texture quality.
Very sharp aircraft.
Excellent runway detail.
Outstanding cockpit readability.
Highest VRAM usage.
Ideal when your graphics card has sufficient VRAM available.
5. GPU Memory Usage
Texture Resolution mainly affects GPU memory usage.
It has a much smaller impact on GPU processing power than settings like:
Clouds.
Render Scaling.
Shadows.
Reflections.
Increasing Texture Resolution does not necessarily mean your GPU has to work dramatically harder.
Instead…
It means the GPU stores larger textures in VRAM.
If there is enough VRAM available, the performance impact can be surprisingly small.
If VRAM becomes full, however, the simulator may have to swap data with system memory, which is much slower.
6. When Does VRAM Become A Problem?
If your graphics card has limited VRAM and you use:
Ultra Textures.
4K resolution.
Large airports.
Photogrammetry.
Complex aircraft.
High Terrain LOD.
High Object LOD.
…VRAM usage can increase significantly.
When VRAM is exhausted, you may experience:
Texture pop-in.
Temporary blurry textures.
Micro-stutters.
Longer loading times.
Inconsistent frame pacing.
This is why monitoring VRAM usage is important.
7. When Does Ultra Matter?
Ultra Texture Resolution is most noticeable when looking at objects close to you.
Examples include:
Cockpit switches.
Navigation displays.
Aircraft liveries.
Runway signs.
Taxiway markings.
Ground vehicles.
If you spend most of your time in detailed airliners or enjoy close-up views, Ultra textures can noticeably improve image quality.
On graphics cards with plenty of VRAM, Ultra often provides this improvement with little effect on FPS.
8. When Is High Enough?
High Texture Resolution is often an excellent choice if:
- Your GPU has limited VRAM.
- You fly at 1440p or 4K with many other demanding settings.
- You prioritise stable performance over maximum texture detail.
For many users, the visual difference between High and Ultra is relatively subtle during normal flight, while the reduction in VRAM usage can provide additional headroom.
9. Choosing The Right Texture Resolution
General guidance:
6GB VRAM
Medium to High depending on your other settings and resolution.
8GB VRAM
High is a strong starting point.
Ultra may be possible depending on the rest of your configuration.
12GB VRAM
High or Ultra will usually work comfortably.
16GB VRAM or More
Ultra Texture Resolution is often a practical choice, assuming other settings are balanced appropriately.
Remember, these are starting points rather than strict rules. Always test on your own hardware.
10. Common Myths
Myth 1
“Ultra textures destroy FPS.”
Not necessarily.
If your graphics card has sufficient VRAM, the FPS difference between High and Ultra can be quite small.
Myth 2
“Texture Resolution is a CPU setting.”
False.
Texture Resolution mainly affects VRAM usage.
Myth 3
“More VRAM automatically means more FPS.”
False.
More VRAM allows your graphics card to store more graphical data efficiently, but FPS is still influenced by many other factors, including GPU processing power and CPU performance.
Student Exercise
Today we’re going to compare Texture Resolution settings.
Step 1
Load your Module 1 benchmark flight.
Use the same:
- Airport
- Aircraft
- Weather

- Graphics settings
Step 2
Test:
Texture Resolution:

If your system has less VRAM, you may also compare Medium.
Step 3
Monitor using HWiNFO or MSI Afterburner:
- Average FPS
- VRAM usage
- GPU utilisation
- GPU temperature
- Cockpit clarity
- Runway markings
- Building textures
- Overall smoothness
Step 4
Compare your results.
Ask yourself:
- Did Ultra noticeably improve image quality?
- Did VRAM usage increase significantly?
- Was there any reduction in FPS?
- Were there any stutters or delayed texture loading?
- Which setting provides the best balance for your graphics card?

Remember:
- Texture Resolution controls the quality of the images applied to 3D objects.
- It mainly affects VRAM usage, not CPU performance.
- VRAM acts as the graphics card’s working memory, storing textures and other graphical data for fast access.
- Texture streaming loads textures dynamically as you fly to make efficient use of available memory.
- Ultra textures provide the highest image quality but require more VRAM.
- High Texture Resolution often delivers an excellent balance between image quality and memory usage.
