My 12GB RTX 4070 Ti runs multiple DLSS 5 layers thanks to one OptiScaler setting
Nothing like an open-source tool to squeeze more power
A user reported that their 12GB RTX 4070 Ti graphics card can handle multiple DLSS 5 layers with the help of one OptiScaler setting. The neural rendering files released by Nvidia for NBA 2K27 have been shared by the open-source and modding community, allowing DLSS 5 to be injected into many games. However, this adds a significant performance cost, especially when multiple neural rendering passes are added.
OptiScaler offers a simple feature that changes what the user can achieve with their 12GB GPU. It reports the RTX 4070 Ti as an RTX 50-series GPU, unlocking multi-frame generation and allowing the use of DLSS 5 and neural rendering in games. By manipulating the order of the neural rendering pass in the pipeline, the user can achieve better performance while still experiencing the visual benefits of DLSS 5.
This technique is particularly useful when running games at high-to-ultra graphics presets with ray tracing at 1440p or 4K resolution, as it prevents the RTX 4070 Ti from reaching its VRAM limit. OptiScaler grants access to DLSS 5 features that even RTX 50-series owners do not have officially, such as adjusting the position of neural rendering in the rendering pipeline and stacking multiple neural rendering passes.
Nvidia's implementation lacks the same level of control over the number of neural rendering passes. The user's experiment demonstrates the power of software-defined DLSS 5 and how open-source tools can push the boundaries of hardware capabilities, even for last-gen GPUs.
