GoKawiilIndependent Tests Show DLSS 5 Carries a Steep Fixed Performance Cost
With frame generation disabled, testing on NBA 2K27 reveals that Nvidia's DLSS 5 imposes a large, largely fixed performance penalty tied to output resolution rather than in-game settings. On an RTX 5090 at max settings, enabling DLSS 5 dropped performance to 76 FPS, and lowering the graphics preset barely helped, gaining just 2 FPS despite a 5% rendering speedup elsewhere.
GoKawiil's interpretation of the reporting above, not reported fact.
Nvidia's own benchmarks relied on 6X Frame Generation to mask the true cost of DLSS 5, obscuring how demanding the underlying neural network pass actually is. These independent on/off comparisons matter because they show gamers the real trade-off: DLSS 5's image quality gains come with a heavy, resolution-bound performance tax that settings tweaks can't offset.
- DLSS 5's performance cost is mostly fixed by output resolution, not scene complexity or settings.
- Lowering in-game graphics presets yields minimal performance gains once DLSS 5 is enabled.
- Nvidia's official DLSS 5 benchmarks used 6X Frame Generation, hiding true on/off performance differences.
