NVIDIA has added DLSS 5 Neural Rendering to Portal with RTX and the Half-Life 2 RTX demo, VideoCardz reports. Portal received its update Oct. 21, followed by the Half-Life 2 demo Oct. 23. The distinction matters: Portal with RTX is a complete release, while the full Half-Life 2 RTX remaster remains in development.
To switch the feature on, players need the latest update and can press Alt+X in-game to open the RTX Remix settings, according to instructions from NVIDIA's Jacob Freeman reproduced by VideoCardz. The option is called 3D-Guided Neural Rendering. In Portal, it is disabled by default.
The Half-Life 2 demo update also adds Frame Generation Preset C, DLSS 4.5 Super Resolution Preset F and up to 6X Multi Frame Generation, according to Freeman's announcement reproduced by Wccftech. VideoCardz says official Neural Rendering support currently targets GeForce RTX 50 Series GPUs and RTX Spark hardware; the new 5X and 6X Multi Frame Generation modes require supported RTX 50 Series hardware.
Both titles use RTX Remix. VideoCardz describes Neural Rendering as using a rendered image and scene information to modify lighting and the appearance of materials. That differs from Super Resolution, which reconstructs a higher-resolution image, and Frame Generation, which creates additional frames, as Wccftech explains. Wccftech notes that the visual changes and performance costs in these games still need independent testing.
