- An enthusiast implemented an experimental integration of DLSS 5 upscaling technology and Neural Rendering in the competitive shooter Counter-Strike 2.
- The mod required a complex technical bridge because Counter-Strike 2 only supports FSR 1.0 and lacks native support for NVIDIA technologies.
- Testing on an RTX 5070 Ti showed a 70% FPS drop due to the multi-layered processing via a third-party API.
- Community testing on Ampere GPUs (RTX 30-series) showed most games tank to single-digit FPS, with some high-end GPUs reaching up to 40 FPS in specific cases.
- Nvidia has not officially announced DLSS 5's release or supported GPUs, but it's deduced that RTX 50-series will be first due to FP8 library support.
- The system generates a synthetic DLAA pass, which is then overlaid with DLSS 5 algorithms and Neural Rendering calculations.
- Due to the lack of direct integration with the game engine, the method does not yet use motion vectors or a depth buffer.
- This significant FPS drop is due to the cost of an additional anti-aliasing pass, inter-system synchronization calls, and frame transfer delays between graphics APIs.
A leaked mod has brought Nvidia's DLSS 5 technology to older Ampere GPUs, but results are disappointing. Users report significant frame rate drops, with many games running in single digits.
An enthusiast implemented this mod in Counter-Strike 2, using a GeForce RTX 5070 Ti as the benchmark platform. The integration required a complex technical bridge due to the game's lack of native support for Nvidia technologies.1
The method involves a special ReShade add-on that processes frames through DirectX 11 and Direct3D 12, generating a synthetic DLAA pass overlaid with DLSS 5 algorithms. However, the lack of direct integration means it does not utilize motion vectors or a depth buffer, leading to a 70% drop in base system performance.
Users have reported varying results: one managed to run *Cyberpunk 2077* at 41 FPS by lowering the resolution to 720p, while others experienced severe drops, with one user reporting just 2 FPS in *Hogwarts Legacy*.
The sentiment among users is mixed; while some are impressed enough to consider upgrading to newer GPUs, the performance issues highlight the challenges of using DLSS 5 on older hardware. Nvidia has yet to officially announce the release of DLSS 5 or its supported GPUs, but it is expected that the RTX 50-series will be the first to receive it due to its compatibility with the necessary FP8 libraries.
“The mod's 70% FPS drop on an RTX 5070 Ti stems from a ReShade-based bridge that intercepts DirectX 11 frames and passes them to Direct3D 12, adding a synthetic DLAA pass. Users report worst-case frametimes multiplying by ten, with one Cyberpunk 2077 run at 7 FPS on an RTX 3080 Ti.”
