Frequently Asked Questions

Can I use DLSS 4.5 on RTX 30 series?

You can use the DLSS 4.5 DLL file for Super Resolution (upscaling) improvements on RTX 20/30 series cards. However, the Frame Generation features are locked to hardware that supports Optical Flow Accelerator (RTX 40 series and newer).

Is DLSS 4.5 safe to use in multiplayer?

Generally, swapping DLLs in competitive multiplayer games (like Call of Duty or Fortnite) carries a risk with anti-cheat software. We recommend using DLSS Swapper or official updates for online titles.
