Troubleshooting Graphics Driver Problems

Estimated Lesson Time: 45–55 Minutes

Lesson Overview

Throughout this module, we’ve learnt how graphics drivers work, how to configure them correctly and how to optimise them for Microsoft Flight Simulator.

However, even a perfectly configured graphics driver can occasionally develop problems.

You may experience:

• Flickering.
• Random crashes.
• Black screens.
• Stuttering.
• Driver timeouts.
• Corrupted installations.
• Poor performance after an update.

When this happens, many users immediately begin changing graphics settings or reinstalling the simulator.

In reality, the problem often lies within the graphics driver itself.

The purpose of this lesson is to teach you how to identify common driver-related problems, understand what causes them and apply the correct solution.

Professional troubleshooting is about following a logical process rather than making random changes.

By the end of this lesson, you’ll know how to restore a stable graphics driver installation with confidence.

1. Recognising Driver Problems

Not every performance issue is caused by your graphics driver.

Before making changes, identify the symptoms.

Common driver-related problems include:

• Screen flickering.
• Driver crashes.
• Black screens.
• Sudden FPS loss after a driver update.
• Visual corruption.
• Display resets.
• Simulator crashing during GPU-intensive scenes.

Correctly identifying the symptom is the first step towards solving the problem.

2. Screen Flickering

What Is Flickering?

Screen flickering is when parts of the display rapidly flash, blink or disappear.

It may occur:

• Inside Microsoft Flight Simulator.
• On the Windows desktop.
• During loading screens.
• After installing a new graphics driver.

Possible Causes

• Driver incompatibility.
• Corrupted driver installation.
• Variable Refresh Rate configuration.
• Display cable issues.
• Monitor firmware.
• GPU overclock instability.

Troubleshooting Steps

• Restart the PC.
• Check monitor cables.
• Disable any unstable overclock.
• Test with G-SYNC or FreeSync temporarily disabled.
• Install a known stable graphics driver if the issue started immediately after an update.

3. Driver Crashes

Sometimes the graphics driver may stop responding before automatically recovering.

Symptoms include:

• The screen briefly goes black.
• Microsoft Flight Simulator freezes.
• Windows displays a notification that the graphics driver has recovered.
• The simulator closes unexpectedly.

Driver crashes can result from:

• Corrupted drivers.
• Unstable overclocks.
• GPU instability.
• Driver bugs.
• Hardware faults.

Always investigate the cause before assuming the graphics card is faulty.

4. TDR Errors

What Is TDR?

TDR stands for:

Timeout Detection and Recovery.

Windows constantly checks whether the graphics driver is responding.

If the GPU stops responding for longer than expected, Windows attempts to restart the driver automatically.

This prevents the entire operating system from crashing.

Symptoms

• Black screen.
• Driver reset.
• Simulator crash.
• Windows notification stating the display driver stopped responding and has recovered.

Common Causes

• Driver instability.
• GPU instability.
• Excessive overclocking.
• Severe GPU workload.
• Hardware faults.
• Rare software conflicts.

Important

A single TDR error does not automatically mean your graphics card is failing.

It simply means Windows detected that the graphics driver became unresponsive.

5. Black Screens

Black screens are one of the most common graphics issues.

Possible causes include:

• Graphics driver failure.
• Display cable problems.
• Refresh rate conflicts.
• GPU instability.
• Driver corruption.
• Monitor issues.

Troubleshooting

Check:

• DisplayPort or HDMI cable.
• Monitor input.
• Driver version.
• Windows Event Viewer.
• GPU temperatures.
• GPU power connections.

Never assume the graphics card is immediately defective.

6. Stuttering After Driver Updates

Many users report stuttering immediately after installing a new graphics driver.

This often occurs because:

• Shader Cache is rebuilding.
• Driver optimisation has changed.
• Background tasks are still running.

Initial stutters after a driver installation are normal.

Give the simulator time to rebuild shader data before evaluating performance.

7. Driver Corruption

Drivers occasionally become corrupted during installation.

Possible causes include:

• Interrupted updates.
• Windows errors.
• Software conflicts.
• Failed installations.

Symptoms may include:

• Poor performance.
• Missing Control Panel options.
• Random crashes.
• Display issues.

If corruption is suspected, perform a clean installation.

8. Clean Driver Installation

A clean installation removes the previous driver before installing the new one.

Benefits include:

• Removes corrupted files.
• Clears outdated components.
• Eliminates conflicting settings.
• Provides a fresh driver installation.

This is often recommended when troubleshooting persistent graphics issues.

9. Display Driver Uninstaller (DDU)

Display Driver Uninstaller (DDU) is a specialist utility that completely removes graphics drivers and their associated files.

Unlike a standard uninstall, DDU removes:

• Driver files.
• Registry entries.
• Driver profiles.
• Cached configuration files.

It is commonly used when:

• Switching GPU manufacturers.
• Resolving severe driver corruption.
• Troubleshooting persistent graphics problems.

Best Practice

Use DDU only when necessary.

Routine driver updates generally do not require it.

10. Driver Rollback

Sometimes a new graphics driver introduces:

• Lower FPS.
• Flickering.
• Instability.
• Simulator crashes.

In these situations, rolling back to a previously stable version is often the best solution.

Keep a record of driver versions that perform well on your system.

Professional optimisers often prioritise stability over having the newest driver.

11. Shader Rebuilds

Whenever a clean graphics driver installation is performed, shader caches may become invalid.

As a result:

• Shaders must be compiled again.
• Initial flights may contain temporary stutters.
• Performance gradually improves as the cache rebuilds.

This behaviour is completely normal.

Do not judge driver performance after only one short flight.

Troubleshooting Workflow

Whenever you encounter a graphics problem, follow this order:

Step 1

Identify the symptom.

Step 2

Determine when it started.

Was it after:

• Driver update?
• Windows update?
• Simulator update?
• New add-on?

Step 3

Check:

• Temperatures.
• GPU utilisation.
• Clock speeds.
• VRAM.

Step 4

Review Windows Event Viewer for graphics-related errors if crashes continue.

Step 5

If necessary:

• Perform a clean driver installation.

Step 6

Only use DDU if standard troubleshooting fails or when changing GPU vendors.

Step 7

Allow the shader cache to rebuild before benchmarking.

Common Myths

Myth 1

“Every new graphics driver should be installed immediately.”

False.

Stability is often more valuable than being on the latest version.

Myth 2

“TDR errors mean the graphics card is broken.”

False.

They indicate the graphics driver became unresponsive, not necessarily a hardware failure.

Myth 3

“DDU should be used every time you update your driver.”

False.

For routine updates, a standard installation is usually sufficient.

Reserve DDU for persistent driver issues, major troubleshooting or when switching GPU manufacturers.

Myth 4

“If performance is poor after updating the driver, the update is bad.”

Not necessarily.

Shader caches may simply be rebuilding.

Complete several flights before drawing conclusions.

Student Exercise

Today you’re going to review your graphics driver installation.

Step 1

Check your current driver version.

Step 2

Ask yourself:

Have you experienced:

• Flickering?
• Driver crashes?
• Black screens?
• Unexplained performance loss?

Step 3

If you’re experiencing persistent driver-related issues:

• Perform a clean graphics driver installation using the manufacturer’s installer.
• Consider DDU only if standard troubleshooting has not resolved the problem or when changing GPU brands.

Step 4

Restart your PC.

Step 5

Launch your Module 1 benchmark flight.

Allow shader compilation to complete naturally.

Step 6

Compare:

• FPS.
• Frame pacing.
• GPU utilisation.
• Overall smoothness.

Record your observations before deciding whether further troubleshooting is necessary.

Student Checklist

Driver version checked.

Symptoms identified.

Clean installation understood.

DDU understood.

Shader rebuild completed.

Benchmark flight completed.

Stability verified.
