How do I fix jagged edges and shimmering on aircraft in Microsoft Flight Simulator?
To fix jagged edges and shimmering on aircraft in Microsoft Flight Simulator, we would first switch to the highest-quality anti-aliasing mode available, run the sim at the display’s native resolution, keep render scaling at 100 or higher, and avoid aggressive upscaling or sharpening. Most aircraft shimmer is an anti-aliasing and image-scaling problem, not a fault with the aircraft itself.
Why do aircraft edges shimmer in MSFS?
We usually see this on thin, high-contrast details: wing edges, antennae, cockpit frames, livery stripes, registration letters, propellers and parked aircraft in the distance. These are exactly the sort of details that produce aliasing, which shows up as crawling, sparkling or jagged lines when the camera moves.
In Microsoft Flight Simulator, the most common causes are:
- Low or compromised anti-aliasing
- Render scaling below native
- Upscaling modes prioritising performance over image stability
- Too much sharpening
- A mismatch between the sim’s resolution and your monitor or TV output
- Some add-on aircraft or liveries using lower-quality textures or mipmaps
That last point matters. If every aircraft shimmers, it is almost certainly a graphics setting issue. If only one aircraft or one livery does it, the model or texture set may be part of the problem.
What settings should we change first?
- Set the sim to your screen’s native resolution.
If your monitor is 1440p or 4K, make sure the simulator is actually rendering at that resolution. Running below native and letting the screen scale the image is one of the quickest ways to get soft edges and shimmer at the same time.
- Use the best anti-aliasing option available.
On PC, the safest starting point is usually TAA. It tends to give the most stable aircraft edges in motion, even if another mode looks a little crisper in a still image.
- Set render scaling to 100.
If it is below 100, the sim is effectively drawing fewer pixels and reconstructing the image. That often saves performance, but aircraft outlines and fine livery details suffer first.
- If you use upscaling, choose the highest-quality mode.
Quality modes are usually the only ones worth trying if shimmer bothers you. Balanced and Performance modes often make thin aircraft details crawl or sparkle, especially when panning the camera.
- Reduce sharpening.
Over-sharpening makes edges look harsh and noisy. It can make the image appear crisp in screenshots while looking worse in motion.
- Restart the flight and test in the same conditions.
Use the same airport, weather and camera view when comparing changes. Otherwise it is very easy to mistake lighting or cloud conditions for a graphics improvement.
Best anti-aliasing settings for jagged edges in Microsoft Flight Simulator
| Setting | Image quality on aircraft | When we would use it |
|---|---|---|
| TAA | Usually the most stable edges and least shimmer | Best starting point if image quality matters more than maximum FPS |
| DLSS Quality | Can look good, but may shimmer more on thin lines and text | Useful if you need better performance and can accept some artefacts |
| Balanced or Performance upscaling modes | Most likely to produce crawling edges and sparkling details | Only if performance is the absolute priority |
| Render scaling above 100 | Can further smooth edges, especially at 1080p or 1440p | Good if you have GPU headroom and want cleaner aircraft outlines |
If your system can handle it, we would normally pick TAA at 100 render scaling first. If you still see obvious aliasing at 1080p or 1440p, try 110 to 120 render scaling. Supersampling like this costs performance, but it is one of the most reliable ways to clean up aircraft edges.
TAA or DLSS for aircraft shimmer?
If the question is purely about reducing shimmer on aircraft, we would usually choose TAA. DLSS can look excellent overall and can be the better performance option, but fine diagonal lines, registrations, antennae and glass framing often look less stable in motion than they do with TAA.
That does not mean DLSS is unusable. If you need the extra frames, use the highest-quality DLSS mode available and keep sharpening modest. Just be aware that what looks sharper while parked may shimmer more once you start panning around the aircraft.
Render scaling matters more than many people think
We often find that people focus on anti-aliasing and ignore render scaling. In MSFS, that is a mistake. A low render scale can undo the benefit of a decent anti-aliasing mode because the simulator is starting from a lower-detail image.
As a rule:
- Below 100: better performance, more shimmer and softer detail
- 100: the baseline we would recommend first
- Above 100: cleaner edges, higher GPU load
At 4K, 100 is often enough. At 1080p, aircraft edges are inherently harder to smooth cleanly, so raising render scaling can help more noticeably if your GPU has room.
Check sharpening, monitor settings and driver overrides
Shimmer is not always coming from the simulator alone. We also see it exaggerated by display and driver settings.
In the simulator
- Lower any sharpening slider if the image looks grainy or sparkly
- Avoid overly aggressive upscaling presets
- Keep resolution and render scale sensible before changing anything else
On the PC or display side
- Make sure the GPU output resolution matches the display’s native resolution
- Set any driver-level image enhancement or forced anti-aliasing back to application controlled if you have experimented
- Turn down TV or monitor sharpness if it is adding artificial edge enhancement
- Disable heavy post-processing on a TV, which can make fine lines flicker more
That last point catches a surprising number of people on larger TVs. What looks like simulator aliasing can actually be the panel’s own sharpening or motion processing making thin aircraft edges sparkle.
If only one aircraft shimmers, is it the add-on?
Sometimes, yes. If the problem is limited to one aircraft, one livery or one repaint set, we would suspect the add-on before the simulator. Fine stripes, low-quality alpha textures, poor mipmaps and very thin model geometry can all create more shimmer than a well-optimised default aircraft.
Try these checks:
- Test a default aircraft.
If the default aircraft looks stable but the add-on does not, the add-on is likely contributing.
- Remove the custom livery.
Some liveries shimmer more because of high-contrast striping or texture work.
- Update the aircraft or repaint.
Visual fixes sometimes come through aircraft updates rather than sim updates.
Can you fix aircraft shimmering on Xbox?
Only partly. Xbox gives you far fewer graphics controls than PC, so you cannot fine-tune anti-aliasing and render scaling in the same way. We would check that the console is outputting at the TV’s native resolution and reduce TV sharpness and image processing, but some shimmer is simply part of the current image pipeline.
If you are on Xbox and notice it mostly on external views in bright daylight, that is fairly typical. It does not necessarily mean anything is wrong with your installation.
Settings combination we would try first
If we wanted the quickest path to a cleaner image on PC, we would use this order:
- Native screen resolution
- TAA
- Render scaling 100
- Sharpening reduced or neutral
- Quality mode only if using upscaling
- Render scaling above 100 if GPU headroom allows
That combination solves most aircraft jaggies without getting lost in endless tweaking.
What if some shimmer still remains?
A small amount is normal. Aircraft models include many thin lines and transparent elements that are hard for any real-time simulator to resolve perfectly, especially when the camera is moving. The goal is to reduce the obvious crawling and sparkle, not to expect every edge to look perfectly static.
If you have already tried TAA, native resolution and 100-plus render scaling, the remaining shimmer is probably the practical limit of the engine, your display resolution, or the aircraft model itself. At that point, chasing more sharpness usually makes the problem worse rather than better.
