After releasing DLSS 4.5’s Super Resolution feature earlier this year, NVIDIA has released an update with DLSS 4.5 features designed to boost frame rates on RTX 50 series cards. Those include DLSS 4.5 Dynamic Multi Frame Generation and DLSS 4.5 Multi Frame Generation 6X. With those, NVIDIA is promising the “smoothest path-traced gaming yet” to unlock the potential for high-refresh 4K 240Hz OLED gaming displays, or 1080p and 1440p monitors at 360Hz and beyond.
The first feature, DLSS 4.5 Dynamic Multi Frame Generation, is like an “automatic transmission” for your RTX 50 series card, NVIDIA said. Rather than multiplying the frame rate by a fixed amount, the AI-powered feature changes it dynamically to strike a balance between refresh rate, image quality and responsiveness. To optimize computing power, it ensures that a game’s frame rate doesn’t exceed your monitor’s native refresh rate, so you won’t play at 240 fps on a 120Hz monitor.
The other key feature, Multi Frame Generation 6X, is designed to deliver even higher levels of performance. Based on NVIDIA’s second-gen transformer model, along with frame pacing and image quality improvements, the feature boosts the maximum multiplier to 6X, generating up to five extra frames for every natively rendered frame on GeForce RTX 50 series GPUs. That will boost 4K frame rates up to 35 percent “with minimal impact to responsiveness,” NVIDIA wrote.
As with Super Resolution, the native frame rate of a game is not accelerated by these features. Rather, the DLSS 4.5 feature uses AI to create interpolated intermediate frames the machine “thinks” should be there. Normally this works fine, but the scheme can create odd artifacts in certain types of scenes, particularly with fine details like rain, hair and phone wires.
Still, the tech allows for smoother gaming with a minimal increase on your GPU’s burden. It’s now available for NVIDIA RTX 50 series cards, and as NVIDIA announced earlier, there are a number of games supporting the MFG features. Those include 007 First Light (May 27th), CONTROL Resonant, Directive 8020 (May 12th) and Tides of Annihilation.
