AMD FSR 4 is Very Impressive: 1440p Upscaling Tested

AMD's FSR 4 offers improved 1440p upscaling, comparable to DLSS 3 with notable clarity but faces stability challenges.

: AMD FSR 4's 1440p upscaling showcases significant advancements, surpassing previous versions with enhanced visual clarity and AI integration. Compared to DLSS 3, FSR 4 shines in texture quality and blur reduction, although stability in motion remains a challenge. The performance boost at 1440p matches DLSS 4, offering an average 20% improvement in Quality mode. While competing well with Nvidia’s DLSS 3, FSR 4's support needs expansion to ensure widespread game compatibility and sustained relevance.

AMD FidelityFX Super Resolution (FSR) 4 marks a significant stride in upscaling technology, particularly for 1440p resolution, demonstrating noticeable improvements over its predecessor, FSR 3. Notably, it employs a hybrid AI approach utilizing CNN and Transformer models to enhance visual quality, aligning more closely with Nvidia's DLSS, which has long dominated the field. This evolution comes as AMD aims to reclaim market share lost to Nvidia's GeForce GPUs due to superior upscaling solutions.

FSR 4's performance is especially prominent when measuring texture quality and reduction of motion blur. In multiple tests, including intensive gaming scenarios, FSR 4 showcased notable advantages in reducing TAA blur, a challenge that DLSS 3 struggles to overcome completely. This has positioned FSR 4 to deliver sharper and crisper images, making it a compelling option for gamers prioritizing clarity in their visual experience.

However, FSR 4's journey isn't devoid of challenges. Critics have pointed out that while FSR 4 has achieved significant progress in image clarity, it still falls short of DLSS 4 in stabilizing images and handling fine details during motion. Instances of aliasing and inconsistencies in edge stability are areas where FSR 4 needs refinement. AMD acknowledges these areas for potential improvement in future iterations, as it seeks to balance clarity with stability effectively.

A critical aspect of assessing FSR 4's impact lies in its potential adoption within the gaming industry. While AMD has initiated strong collaborative efforts, particularly with Sony for project development, game support remains less extensive compared to Nvidia's DLSS. NVIDIA's extensive groundwork with DLL easy upgrades provides them a broader support spectrum, which is an area where AMD needs to focus and expand to ensure broader compatibility and availability of FSR 4 across titles.

The comparison between FSR 4 and DLSS 4 will likely shape many purchasing decisions. While DLSS 4 retains its edge with higher image quality combining both clarity and stability, the reduced gap in visual performance between FSR 4 and DLSS 3 offers AMD a stronger competitive stance than before. Future decisions by consumers will hinge not solely on upscaling capability but also on pricing dynamics, where AMD's offering could win over users seeking efficiency without heavy financial trade-offs.
