英偉達公布 DLSS 4 支援：《生化危機 9：安魂曲》《紅色沙漠》《毒液突擊隊》

🔑 增強重點摘要

• •DLSS 4.5 introduces a second-generation transformer model for Super Resolution, leveraging FP8 precision on RTX 40/50 Series GPUs to double inference throughput with minimal performance loss[1][2][3].
• •Dynamic Multi Frame Generation in DLSS 4.5 enables up to 6X frame multipliers exclusively on RTX 50 Series GPUs, dynamically adjusting for smoother 4K 240Hz path-traced gaming with up to 35% FPS uplift[1][3][4].
• •DLSS 4.5 Super Resolution model uses five times the compute of DLSS 4's transformer, reducing shimmering on static surfaces and ghosting behind moving objects like weapons[3][4].

🛠️ 技術深入

• •Second-generation transformer Super Resolution model supports FP8 precision on Ada Lovelace and Blackwell GPUs, enabling faster performance despite 5x compute increase over DLSS 4[1][3].
• •Dynamic Multi Frame Generation (DMFG) automatically adjusts frame multipliers up to 6X based on target FPS set in NVIDIA App, improving frame-time pacing and supporting up to 5 generated frames per source frame[3][4].
• •DLSS 4.5 enhances Performance and Ultra Performance modes to match or exceed native image quality at 4K, with improved anti-aliasing, temporal stability, and reduced ghosting via extensive AI training on edge cases[1][4][6].
• •Available via NVIDIA App overrides (e.g., model M for general use, model L alternative) on all RTX GPUs for Super Resolution; DMFG exclusive to RTX 50 Series in spring 2026[3].
