Nvidia pushed an update through its App that appeared aimed at disabling unofficial mods enabling DLSS Multi-Frame Generation on RTX 40-series GPUs, a feature officially reserved for the newer RTX 50 Blackwell cards. Modders quickly found workarounds, restoring the feature across several games including Resident Evil 9 and Forza Horizon 6 within hours of the update landing.
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.
Nvidia confirmed it will officially extend DLSS 5 support to RTX 40-series graphics cards, though the rollout will happen only after performance tuning for RTX 50-series GPUs is complete. The move comes after modders reverse-engineered and ported a leaked version of DLSS 5 to run on older cards, including RTX 30 and RTX 20 series, with mixed results. Nvidia also clarified that gamers will only get a simple on/off toggle for DLSS 5, while granular controls like Structure Intensity and Tone Intensity remain reserved for developers.
Nvidia's newly released 615.56 driver blocks the core power limit adjustments that the third-party utility mVolt+ used to push RTX 50-series GPUs well past their rated power limits. Users report the screen goes black, mimicking a driver crash, whenever the tool tries to apply extra current, regardless of the settings used. The app had previously let enthusiasts drive cards like the RTX 5090 to 650-700W and an Asus ROG Astra RTX 5080 to 680W without VBIOS swaps or hardware mods.
