Module Review & Complete GPU Optimisation

Estimated Lesson Time: 45–60 Minutes

Lesson Overview

Over the past fourteen lessons, you’ve developed a deep understanding of how graphics drivers influence Microsoft Flight Simulator and how to optimise them for your own hardware.

You’ve learned that successful optimisation isn’t about copying settings from YouTube videos or forums—it’s about understanding how your system works, measuring its performance and making informed decisions based on real data.

In this final lesson, you’ll review everything you’ve learned before completing your own fully customised GPU driver profile.

You’ll then benchmark your system using the same flight you created in Module 1 and compare the results to your original baseline.

This allows you to measure the true impact of your driver-level optimisations before moving on to later modules.

Lesson Objectives

By the end of this lesson you will:

Understand every major GPU driver optimisation covered in Module 4.

Build a complete NVIDIA or AMD driver profile tailored to your hardware.

Benchmark your simulator using a consistent testing methodology.

Compare performance against your Module 1 baseline.

Identify which optimisations produced the greatest improvements.

Develop a repeatable workflow for future graphics driver updates.

Module Review

Before beginning your final practical assignment, let’s recap the key concepts covered throughout Module 4.

NVIDIA Control Panel

You learned:

• How NVIDIA Control Panel interacts with Microsoft Flight Simulator.
• The difference between Global Settings and Program Settings.
• Why Flight Simulator should have its own dedicated profile.
• Which settings genuinely affect the simulator and which are largely legacy features.

The key lesson was simple:

Only change settings when you understand what they do.

AMD Adrenalin

You explored:

• AMD’s graphics driver software.
• Radeon-specific optimisation features.
• FreeSync.
• Anti-Lag.
• Radeon Image Sharpening.
• Driver management.

You also learned that AMD and NVIDIA achieve many of the same goals using different technologies.

DLSS

You learned:

• How DLSS renders at a lower internal resolution before reconstructing the image.
• The benefits of Tensor Core AI processing.
• Which DLSS modes suit different resolutions.
• Why DLSS is primarily a GPU optimisation.

Most importantly:

DLSS reduces GPU workload, not CPU workload.

FSR

You explored:

• AMD FidelityFX Super Resolution.
• FSR Quality Modes.
• Hardware compatibility.
• Performance versus image quality.
• Differences between FSR and DLSS.

You learned that FSR offers broad compatibility and can be an excellent choice on both AMD and many NVIDIA graphics cards.

Frame Generation

You learned:

• How Frame Generation creates AI-generated intermediate frames.
• Why it improves perceived smoothness.
• Why it doesn’t reduce CPU bottlenecks.
• The importance of pairing it with NVIDIA Reflex on supported hardware.

NVIDIA Reflex

You learned:

• What input latency is.
• How the render queue works.
• Why Reflex reduces latency rather than increasing FPS.
• The relationship between Reflex and Frame Generation.
• Why responsiveness matters just as much as frame rate.

G-SYNC, FreeSync & Variable Refresh Rate

You explored:

• Screen tearing.
• Monitor refresh rates.
• G-SYNC.
• FreeSync.
• Adaptive Sync.
• V-Sync.
• FPS caps.

You learned that smooth frame delivery often feels better than simply chasing the highest possible FPS.

Shader Cache

You now understand:

• What shaders are.
• Why shader compilation occurs.
• Why caches exist.
• When to rebuild them.
• Why shader stutters are often temporary.

You also learned that Shader Cache is a troubleshooting tool—not something to clear routinely.

GPU Monitoring

You learned how to monitor:

• GPU utilisation.
• VRAM usage.
• GPU clock speeds.
• GPU temperatures.
• GPU power draw.

Using tools such as:

• MSI Afterburner.
• HWiNFO.
• NVIDIA App Performance Overlay.

Most importantly, you learned how to interpret these values rather than simply observing them.

Driver Optimisation

Finally, you learned:

• When to update graphics drivers.
• When to wait before updating.
• How to perform a clean installation.
• When to use Display Driver Uninstaller (DDU).
• How to roll back to a stable driver.
• How to troubleshoot graphics driver problems professionally.

Bringing Everything Together

You now have all the knowledge required to create a professional GPU driver profile.

Remember these principles:

• Optimise for your hardware, not someone else’s.
• Change one setting at a time.
• Measure before and after.
• Prioritise smoothness and consistency over chasing the highest FPS.
• Keep a record of your working configuration.

A stable, well-tested system is far more valuable than a constantly changing one.

Practical Assignment – Build Your Complete GPU Driver Profile

It’s now time to apply everything you’ve learned.

Step 1 – Identify Your Hardware

Record:

• Graphics Card
• CPU
• RAM Capacity
• Monitor Resolution
• Monitor Refresh Rate
• NVIDIA or AMD Driver Version

Step 2 – Configure Your Graphics Driver

Using everything you’ve learned throughout this module:

Configure:

• NVIDIA Control Panel or AMD Adrenalin.
• G-SYNC or FreeSync (if supported).
• NVIDIA Reflex or AMD Anti-Lag (where appropriate).
• Shader Cache settings.
• Preferred refresh rate.
• Power management.
• Texture filtering.
• Driver-specific features.

Avoid changing settings you do not fully understand.

Step 3 – Launch Your Benchmark Flight

Use the exact benchmark flight you created in Module 1.

Keep everything identical:

• Airport.
• Aircraft.
• Weather.
• Time of day.
• Camera position.
• Route.

This ensures your comparison remains accurate.

Step 4 – Record Your Performance

During the flight, record:

Performance

• Average FPS.
• 1% Lows (if available).
• Lowest FPS.
• Highest FPS.

GPU Metrics

• GPU Utilisation.
• VRAM Usage.
• GPU Clock Speed.
• GPU Temperature.
• GPU Power Draw.

CPU Metrics

• MainThread Status.
• CPU Utilisation (if available).

Overall Experience

Record your observations:

• Smoothness.
• Frame pacing.
• Input responsiveness.
• Loading behaviour.
• Visual quality.
• Any stutters or anomalies.

Step 5 – Compare Against Your Module 1 Baseline

Open the Performance Baseline Report you created in Module 1.

Compare:

• Average FPS.
• Lowest FPS.
• Highest FPS.
• GPU utilisation.
• VRAM usage.
• MainThread status.
• Frame pacing.
• Overall smoothness.

Ask yourself:

• Which driver-level changes had the greatest impact?
• Did image quality improve without sacrificing smoothness?
• Has GPU utilisation become more consistent?
• Are temperatures stable throughout the flight?
• Does the simulator feel more responsive?
• Have stutters been reduced?

Remember that the best optimisation is not always the one with the highest FPS—it is the one that delivers the most consistent and enjoyable flying experience.

Lesson Summary

Congratulations.

You have successfully completed Module 4 of the Performance Academy.

You now understand how graphics drivers interact with Microsoft Flight Simulator and how to configure them professionally.

You’ve learned that optimisation isn’t about copying settings—it’s about understanding your hardware, measuring its behaviour and making informed decisions based on evidence.

By building and validating your own driver profile, you’ve created a strong foundation for the remaining modules in this course.

As you continue through the Performance Academy, you’ll build on this knowledge to optimise every aspect of your simulator, always using the same professional approach: measure, understand, adjust, test and validate.
