Nvidia Releases DLSS 4.5 Impacting Older RTX Cards
8.0
Nvidia released DLSS 4.5 with its latest driver today, and early benchmarks show notable slowdowns on older RTX cards, particularly an up to 24% FPS drop on an RTX 3080 Ti in Cyberpunk 2077 at 4K RT Ultra. Nvidia warns DLSS 4.5 is about five times more tensor-core intensive and leverages FP8 only on RTX 40/50 series, so users should test presets (M/L/J/K) per game to balance quality and performance.
Key Points
- 1Reports show up to 24% FPS reduction on an RTX 3080 Ti in Cyberpunk 2077 at 4K RT Ultra.
- 2DLSS 4.5 uses a model five times more tensor-core intensive and relies on FP8 for mitigation.
- 3Recommend testing DLSS presets (M/L/J/K/L) per game and resolution to trade image quality for speed.
Scoring Rationale
Notable DLSS upgrade with clear performance trade-offs and official data; limitation is its primary impact on older RTX cards.
