How Forza Horizon 6 Changed My Mind on Upscaling Technology
I have been openly skeptical about the latest generation of upscaling since its announcement. Many claims felt too good to be true. Promises of better image quality with lower performance costs often left me disappointed in practice. Then Microsoft released Forza Horizon 6 for PC Game Pass subscribers. Nvidia prepared a Game Ready Driver ahead of that launch. The combination of this new open-world racing title and the updated DLSS 4.5 technology created a perfect testing ground. After spending hours driving through Japan, my doubts evaporated completely.
The Visual Splendor of Japan Demands More Power
Forza Horizon 6 transports players to Japan for the first time in the series. Playground Games crafted an environment that feels alive. The neon-drenched streets of Shinjuku District glow at night. Snow blankets the mountain passes near Mount Fuji. Countryside villages offer quiet escapes from the city chaos. Cherry blossom petals drift across roads during spring races.
This beauty comes from photogrammetry. The same technique used in Microsoft Flight Simulator 2024 captures real-world data. Developers scanned actual locations to build digital versions. The result is an open world that tempts you to slow down. You want to admire the details rather than race past them.
The visual ambition creates a heavy performance burden. Ray-traced reflections bounce off every wet surface. Volumetric weather systems fill the sky with dynamic clouds. Dense flora and fauna populate the countryside. Even powerful graphics cards struggle at native resolution. This is exactly the scenario where intelligent upscaling can shine.
Why Native Resolution No Longer Makes Sense
Running a game at your monitor’s native resolution sounds ideal. The reality is different. Modern games push graphical boundaries further with each release. The hardware cannot always keep pace. You face a choice between lower settings or lower frame rates. Neither option feels satisfying.
DLSS 4.5 offers a third path. It renders the game at a lower internal resolution. Then it uses machine learning to reconstruct the final image. The second-generation transformer model handles this task better than previous versions. Details remain sharp. Edges stay clean. Motion looks smooth.
Forza Horizon 6 benefits enormously from this approach. The game’s dense environments contain countless small details. Leaves on trees. Grains of sand. Reflections in puddles. Earlier upscaling methods might blur these elements. The transformer model preserves them remarkably well.
My Testing Setup and Methodology
I wanted concrete numbers rather than subjective impressions. My test system featured an RTX 4070 Ti Super paired with a Ryzen 5 7600X. The resolution was 1440p with the Extreme preset enabled. Ray-traced reflections were set to High. This configuration pushes the hardware hard at native resolution.
I ran three separate tests using the game’s built-in benchmark. The first used DLAA as a baseline for native resolution performance. The second used DLSS Quality on Preset L. The third used DLSS Quality on Preset M. Both presets represent the latest transformer models available in DLSS 4.5.
The benchmark runs through a varied section of the world. It includes city streets, countryside roads, and mountain passes. This provides a realistic representation of gameplay performance. The results surprised me in several ways.
Performance Gains That Exceeded Expectations
DLAA delivered 73 frames per second at native 1440p. This is playable but leaves little headroom. Drops below 60 FPS would feel noticeable during intense races. The system was working hard to maintain that number.
Switching to DLSS Quality on Preset M changed everything. The frame rate jumped to 94 FPS. That represents a 29 percent improvement over the native baseline. The game felt noticeably smoother. Camera movements became more fluid. Cornering at high speeds felt more responsive.
Preset L performed similarly at 92 FPS. The gap between the two presets is narrow. Both deliver substantial improvements over native rendering. The consistency of frame delivery impressed me most. The 1% low values stayed high, meaning stutters were rare.
The Latency Reduction Changed My Driving Experience
Frame rates tell only part of the story. Input latency matters just as much in a racing game. Every millisecond of delay affects your ability to react. A late steering input can send you into a wall. Delayed braking can ruin a perfect corner entry.
Average latency with DLAA sat at 40.8 milliseconds. This is acceptable but not ideal. Switching to DLSS Quality on Preset M dropped that number to 30.1 milliseconds. That is a 25 percent reduction. The improvement comes from Reflex integration managing the render queue more efficiently.
The difference is immediately noticeable in gameplay. Steering inputs feel more direct. The car responds faster to your commands. You can push closer to the limit without fear of delayed reactions. This transforms the driving experience from good to exceptional.
How Reflex Integration Makes the Difference
Nvidia Reflex works alongside DLSS to reduce system latency. It synchronizes the CPU and GPU more effectively. The render queue stays shorter. Inputs reach the display faster. The combination creates a responsive feel that native rendering cannot match.
In Forza Horizon 6, this matters at every speed. City driving requires precise steering through tight streets. Off-road sections demand quick corrections on loose surfaces. High-speed straights need stable control at over 200 miles per hour. Lower latency improves all these scenarios.
The 25 percent reduction I measured translates to real competitive advantage. You can brake later into corners. You can accelerate earlier out of them. The car feels connected to your hands rather than separated by processing delays.
Image Quality That Preserves Artistic Intent
Performance improvements mean nothing if the image looks worse. Earlier upscaling technologies often introduced artifacts. Ghosting behind moving objects. Flickering on thin details. Blurring in motion. These issues made me skeptical of the entire approach.
DLSS 4.5 addresses these concerns effectively. The second-generation transformer model handles temporal information better. Motion remains clear without ghosting. Fine details like power lines and tree branches stay visible. The image looks natural rather than processed.
Forza Horizon 6 benefits from this fidelity. The cherry blossom trees contain thousands of individual petals. Wind moves them dynamically. Earlier upscaling might blur this effect. The transformer preserves the delicate movement. The artistic vision of the developers remains intact.
Comparing Preset L and Preset M Quality
Both presets deliver excellent image quality. The differences are subtle rather than dramatic. Preset M offers slightly sharper edges on distant objects. Preset L provides marginally better stability in motion. Neither introduces obvious artifacts or blurring.

I preferred Preset M for its overall consistency. The slight sharpness improvement makes the world feel more defined. Textures on road surfaces look clearer. Building details in city environments appear more distinct. The performance advantage is also slightly better.
Preset L remains an excellent choice for those who prioritize stability. The motion handling is slightly smoother during fast camera pans. The difference is small enough that most players would not notice. Both options represent a significant improvement over native rendering.
Why This Technology Represents a Turning Point
DLSS 4.5 convinced me that upscaling is not a compromise. It is an enhancement. The technology improves both performance and image quality simultaneously. It reduces latency while maintaining visual fidelity. This combination was previously impossible.
The Forza Horizon 6 implementation demonstrates mature technology. The transformer model handles complex scenes without breaking. Dense urban environments with neon signs and reflections look stunning. Open countryside with rolling hills and distant mountains remains clear. The upscaler adapts to different scenarios intelligently.
This represents the most thoughtful approach to upscaling I have encountered. The technology operates as a supportive utility. It enhances the core game experience rather than diminishing it. The original artistic intent of the developers is amplified rather than compromised.
What This Means for Future Game Releases
Forza Horizon 6 sets a new standard for visual quality in open-world racing games. The combination of photogrammetry and intelligent upscaling creates something special. Players can experience the beauty of Japan without sacrificing performance. This balance was previously unattainable.
Other developers will likely follow this approach. The technology is available across all RTX graphics cards. Game Ready Drivers optimize for specific titles. The ecosystem supports widespread adoption. Future games can push visual boundaries further knowing that upscaling can handle the demands.
The debate about DLSS 5 continues in the community. For now, version 4.5 represents a mature and capable solution. It delivers on the promises that earlier versions made. The second-generation transformer model proves that machine learning can enhance gaming experiences meaningfully.
Practical Advice for Players
If you own a compatible graphics card, enable DLSS immediately. The performance gains are substantial. The image quality is excellent. The latency reduction improves your driving experience. There is no reason to run Forza Horizon 6 at native resolution.
Start with DLSS Quality on Preset M. This offers the best balance of performance and quality. If you need higher frame rates, experiment with Balanced or Performance modes. The transformer model handles lower internal resolutions better than previous versions.
Enable ray-traced reflections if your system can handle them. The visual improvement is significant in wet conditions and urban environments. The reflections add depth and realism that static cube maps cannot match. DLSS helps offset the performance cost of this feature.
Check for the latest Game Ready Driver before playing. Nvidia released specific optimizations for Forza Horizon 6. These drivers ensure the best possible experience. The optimization work behind them leaves no stone unturned.
System Requirements and Recommendations
The game runs on a wide range of hardware. Lower-end systems can use DLSS to achieve playable frame rates. Higher-end systems can push for maximum visual quality. The technology scales well across different configurations.
My RTX 4070 Ti Super at 1440p represents a sweet spot. The card handles the Extreme preset with ray tracing enabled. DLSS Quality provides headroom for consistent high frame rates. Lower-tier cards can achieve similar results at lower presets.
CPU choice matters less than GPU in this title. The Ryzen 5 7600X handled the game without bottlenecking. The Reflex integration ensures that input latency stays low regardless of CPU load. Focus your budget on the graphics card for the best experience.
