With the release of DLSS 4.5, hardware compatibility varies depending on which feature you want to use. While the core upscaling tech is widely compatible, the advanced AI frame generation is exclusive to newer cards.

Detailed Breakdown
GeForce RTX 50 & 40 Series
These are the only cards with the Optical Flow Accelerator (OFA) required for smooth Frame Generation. They support every feature DLSS 4.5 offers, including the improved multi-frame interpolation.
GeForce RTX 30 & 20 Series
While you cannot enable Frame Generation, you can still update the DLSS DLL file to version 4.5. This will improve image stability, reduce ghosting, and better handle fine details like wire fences or text compared to older DLSS 2.4 DLLs.
Common Questions
Can I use DLSS 4.5 on GTX 1660 or 1080 Ti?
No. DLSS requires Tensor Cores, which are only found on RTX cards. For GTX cards, you should look into FSR 3 or NVIDIA NIS.
Why doesn't my RTX 3080 support Frame Gen?
While RTX 30 cards are powerful, their optical flow hardware is significantly slower than that in the 40/50 series. Enabling Frame Gen would likely result in worse performance or severe visual artifacts.
