6千人盲測選出最強畫質：玩家更喜歡DLSS 4.5而非原生或FSR 4

• DLSS 4.5 uses transformer-based upscaling architecture for improved image reconstruction • FSR 4 (Redstone) employs spatial upscaling with softer filtering characteristics • Both technologies tested at 4K resolution with Quality presets enabled • DLSS 4.5 shows 20%+ performance loss on older RTX 30 and 20 series GPUs compared to DLSS 4.0 • FSR 4 achieves higher raw performance gains but at the cost of perceived image softness • Test methodology used identical gameplay footage with blind voting to eliminate bias from branding

DLSS 4.5's decisive victory in blind testing suggests Nvidia's transformer-based upscaling approach has achieved meaningful perceptual quality advantages over AMD's FSR 4 technology. This outcome may influence game developer adoption decisions, with potential acceleration of DLSS 4.5 integration in upcoming titles. However, FSR 4's superior raw performance gains (179% vs 128% at 1080p) indicate AMD's technology remains competitive for performance-focused gamers willing to accept softer image presentation. The test results underscore the ongoing quality-versus-performance tradeoff in upscaling technologies and may drive AMD to refine FSR's sharpness characteristics in future iterations to close the perceptual quality gap.
