Borderless Gaming, a paid utility on Steam, has added support for an unofficial implementation of NVIDIA DLSS 5 Neural Rendering, as reported by VideoCardz.
What makes this notable is the installation method. VideoCardz reports that, unlike many recent DLSS 5 experiments, this version does not require users to replace game DLLs, modify game files, or install a game-specific mod. Instead, the effect is downloaded separately from GitHub and loaded through Borderless Gaming’s existing BGFX scaling system.
The Neural Rendering effect is not included in the Borderless Gaming update itself. Users who want to try it still need to install the shader separately, VideoCardz reports.
What the effect adds
According to the update notes cited by VideoCardz, the effect exposes controls for strength, lighting, structure, style, and processing resolution. That suggests Borderless Gaming is treating the feature as an adjustable post-process-style effect inside its broader effects pipeline, rather than as native, game-integrated DLSS support.
VideoCardz attributes several technical claims to the developer, including that the model was quantized, modified in how it runs, and stripped of bottlenecks. Rather than forwarding requests through NVIDIA’s own DLLs, the developer said the model runs directly through BGFX.
The same report says the implementation uses experimental shader technology, with more performance expected as Shader Model 6.10 support improves in drivers.
How it compares with official support
Performance will vary. VideoCardz attributes to the developer a claim that even a GeForce RTX 3090 can target around 30 FPS, depending on the game and settings.
That remains distinct from NVIDIA’s official rollout. VideoCardz notes that NVIDIA officially supports DLSS 5 Neural Rendering on GeForce RTX 50-series cards and plans to work on RTX 40-series support after further optimization for RTX 50 hardware.
There is also an important technical difference between this unofficial effect and native game support. As VideoCardz notes, NVIDIA’s own implementation is integrated into the game pipeline and uses engine data such as the rendered frame and motion vectors. Borderless Gaming’s version, by contrast, is being loaded through BGFX as a separate effect, so it should not be confused with official in-engine support.
In practice, that makes this less of a standard DLSS rollout than another sign that neural rendering features are starting to spread beyond the narrow hardware and software combinations NVIDIA officially supports.
