NVIDIA's latest RTX 40 series graphics cards feature impressive new technologies like DLSS 3 that can significantly enhance performance and image quality in games. However, owners of older 20 and 30 series NVIDIA GeForce RTX cards cannot officially benefit from these cutting-edge advances. DLSS 3's Frame Generation feature, in particular, requires dedicated hardware only found in NVIDIA's brand new Ada Lovelace architecture. But the ingenious modding community has stepped in with a creative workaround solution where NVIDIA has refused to enable DLSS 3 functionality on older generation hardware. A new third-party modification can unofficially activate both FSR 3 upscaling and AMD Fluid Motion Frames on older NVIDIA cards equipped with Tensor Cores. Replacing two key DLL files and a small edit to the Windows registry enables DLSS 3 to be activated in games running on older hardware.

In testing conducted by Digital Foundry, this modification delivered up to a 75% FPS boost - on par with the performance uplift official DLSS 3 provides on RTX 40 series cards. Games like Cyberpunk 2077, Spider-Man: Miles Morales, and A Plague Tale: Requiem were used to benchmark performance. However, there can be minor visual flaws, including incorrect UI interpolation or random frame time fluctuations. Ironically, while the FSR 3 tech itself originates from AMD, the mod currently only works on NVIDIA cards. So, while not officially supported, the resourcefulness of the modding community has remarkably managed to bring cutting-edge upscaling to more NVIDIA owners - until AMD RDNA 3 cards can utilize it as well. This shows the incredible potential of community-driven software modification and innovation.
 
The mod community continues to impress me.
