FSR 4 is Even Better at 4K

Summary

This video compares FSR4 and DLSS4 at 4K resolution, highlighting FSR4's improvements over FSR 3.1 and its performance relative to Nvidia's DLSS. FSR4 offers notable enhancements in image quality, stability, and clarity, especially in the performance and quality modes. While DLSS4 still holds the edge in terms of overall stability and detail, FSR4 provides a very competitive experience, especially in 4K gaming. The video also discusses AMD's slow game support for FSR4, which limits its full potential, but overall, FSR4 proves to be a substantial upgrade over its predecessor and is increasingly usable for 4K gaming.

Takeaways

• 😀 FSR4 significantly improves over FSR 3.1, especially at 4K resolution, offering better stability, sharpness, and image clarity.
• 😀 FSR4's performance mode at 4K is now much more usable than FSR 3.1's performance mode, providing a notable upgrade in quality.
• 😀 DLSS4 remains the most stable and detailed upscaler, but FSR4 offers competitive performance and image quality, often surpassing DLSS3.
• 😀 At 4K, FSR4 reduces TAA-related blur and improves image quality, though it still lags behind DLSS4 in terms of texture quality preservation.
• 😀 FSR4 at 4K is more stable than at 1440p, with fewer visible artifacts like shimmering or sizzling, making it more reliable for gaming.
• 😀 While DLSS4 offers the best overall image quality and texture fidelity at 4K, FSR4's performance is closer to DLSS3 but still highly competitive.
• 😀 The quality of transparencies, like fire and holograms, is significantly improved in FSR4, with better handling of particles and rain compared to earlier versions.
• 😀 FSR4 outperforms FSR 3.1 in various scenarios, especially with fine details like grass and foliage, where it rivals DLSS3 and sometimes DLSS4.
• 😀 FSR4’s quality and stability are noticeably better at 4K than at 1440p, particularly in its performance and balanced modes.
• 😀 AMD's lack of day-one FSR4 game support remains a significant challenge, as many games with FSR 3.1 don't yet support FSR4, limiting its widespread adoption.

Q & A

How does FSR4 compare to DLSS4 at 4K resolution?

At 4K, FSR4 is very competitive but still not as impressive as DLSS4. DLSS4 provides superior texture quality and image stability, particularly in motion. However, FSR4 is quite usable, especially compared to DLSS3, and offers a noticeable improvement over FSR3, especially in performance modes.

What improvements did FSR4 show over FSR 3.1 at 4K?

FSR4 offers a significant improvement over FSR 3.1 at 4K, providing better image clarity, sharpness, and stability. Details like hair, transparencies, and fine textures (e.g., grass) are much improved, and there's less noticeable graininess or instability in the image.

Does FSR4 perform well in the performance mode at 4K?

Yes, FSR4's performance mode at 4K is surprisingly usable, offering an acceptable image quality. It provides better clarity and stability compared to FSR3, which was previously not recommended at this resolution, especially in performance mode.

How does FSR4 handle TAA-related blur compared to DLSS4 at 4K?

FSR4 does a good job of reducing or eliminating TAA-related blur at 4K, though it's a bit less impressive than DLSS4. While FSR4's quality mode is generally better than DLSS3 in this aspect, DLSS4 still outperforms FSR4 when it comes to preserving texture quality in motion.

What are the advantages of using FSR4 over FSR 3.1 for 4K gaming?

FSR4 brings substantial upgrades over FSR 3.1, especially in terms of image quality, stability, and performance. The quality mode offers a clearer and sharper image, and the performance mode is now usable, making FSR4 a much more suitable choice for 4K gaming.

Is FSR4 at 4K more stable than FSR3 at 1440p?

Yes, FSR4 at 4K is more stable than FSR3 at 1440p. Higher resolution helps reduce issues like shimmering and instability, making FSR4 a more reliable option at 4K, even in performance or balanced modes.

What is the trade-off when using FSR4 in performance mode at 4K?

The main trade-off when using FSR4 in performance mode at 4K is a slight loss of fine detail, especially compared to DLSS4, which retains more detail and stability. However, FSR4 in performance mode still offers a usable image quality, especially in comparison to FSR3.

How does FSR4 perform in terms of handling foliage and grass quality at 4K?

FSR4 performs well with foliage and grass quality at 4K, often sitting between DLSS3 and DLSS4 in terms of clarity. Grass looks particularly good in FSR4’s quality mode, and tree stability improves over 1440p, though DLSS4 remains superior for fine details.

What are the limitations of FSR4 in terms of game support?

The main limitation of FSR4 is its lack of widespread game support. AMD has been slow in rolling out FSR4 updates for existing games, and while FSR3 titles should be upgradable to FSR4, many titles still lack this support. In contrast, DLSS4 is more widely adopted and supported from launch.

How does FSR4 compare to DLSS4 in terms of FPS performance at 4K?

At 4K, FSR4 offers a similar performance uplift as DLSS4. The quality mode of FSR4 delivers a 35% performance increase, while DLSS4 offers a 31% gain. Both upscalers are more demanding than their previous versions but provide notable improvements in image quality, making the performance trade-off worthwhile.
