Could RTX 30 owners get a taste of DLSS 4’s Frame Generation magic? NVIDIA’s VP of Applied Deep Learning Research, Bryan Catanzaro, didn’t shut the door on the idea at CES 2025, leaving fans with a glimmer of hope for their GPUs.
DLSS 4: Smarter, Faster, and More Advanced
At CES 2025, Bryan Catanzaro spoke with Digital Foundry about NVIDIA DLSS 4, detailing the leaps forward in Super Resolution, Ray Reconstruction, and Frame Generation. The key upgrade? Transformers replacing CNNs for Super Resolution and Ray Reconstruction. These advanced AI models are smarter, capable of learning from larger datasets, and produce fewer visual artifacts like shimmering or ghosting.
Catanzaro emphasized that DLSS 4’s new Super Resolution model delivers four times the compute power of its predecessor, though he didn’t share the rendering time cost. What’s clear is that DLSS 4 is tailored to the upcoming GeForce RTX 50 cards, set to launch this month.
Frame Generation Goes Fully AI
NVIDIA has reimagined Frame Generation for DLSS 4, ditching the Optical Flow hardware accelerator in favor of a fully AI-driven model. Why the change? Optical Flow, while groundbreaking, had its limitations:
“The failures that arose from hardware Optical Flow couldn’t be undone with a smarter neural network,” Catanzaro explained. “So we replaced it with a fully AI-based solution.”
This new approach leans heavily on Tensor Cores but is surprisingly efficient:
- Less VRAM usage.
- Improved image quality, crucial for the Multi Frame Generation feature on RTX 50 GPUs.
- Better efficiency, as the AI cost is spread across multiple frames.
Could Frame Generation Come to RTX 30 Series?
When asked if this shiny new Frame Generation model could be adapted for older GPUs like the RTX 30 series, Catanzaro left fans with hope:
“It’s a question of optimization, engineering, and the ultimate user experience. We’ll see what we can squeeze out of older hardware.”
Here’s the twist: the older Optical Flow hardware accelerator limited Frame Generation to RTX 40 cards. Now, with Optical Flow out of the picture, the possibility for RTX 30 support is less far-fetched—if the Tensor Core performance can keep up.
Reflex 2: Making Gameplay Feel Right
Beyond DLSS 4, NVIDIA’s Reflex 2 technology promises even greater responsiveness by decoupling flip metering from the CPU. This reduces frame time variability by 5–10x, delivering smoother frame pacing. Catanzaro also highlighted Reflex 2’s ability to make gameplay feel more “connected,” a boon for latency-sensitive gamers.
What’s Next for NVIDIA DLSS?
NVIDIA’s DLSS 4 is raising the bar for AI-driven performance enhancements, but will older hardware reap the rewards? Only time (and NVIDIA engineers) will tell. Until then, the RTX 50 Series is shaping up to be the ultimate playground for this cutting-edge tech.
