I've been streaming games to headsets since the feature was barely functional, back when GeForce NOW VR support felt more like a proof of concept than a product. Choppy frames, visible latency, the kind of experience that made you reach for the Advil after twenty minutes. So when NVIDIA quietly bumped VR streaming to 90fps during GDC week, I sat up.
This is a bigger deal than the spec bump suggests.
The 90fps threshold is real
For anyone who hasn't spent time in a headset, 60fps sounds fine. It's fine on a monitor. In VR, 60fps is the floor where your vestibular system starts filing complaints. You can feel the difference between 60 and 90 in your stomach before you notice it with your eyes. It's the gap between "I can tolerate this" and "I forgot I'm wearing a headset."
Starting March 19, GeForce NOW Ultimate members streaming to Apple Vision Pro, Meta Quest, and Pico devices get 90fps. That's the native refresh rate target for most of these headsets. NVIDIA is finally matching the hardware's expectations instead of asking users to settle.
For cloud-powered spatial computing, this matters enormously. The whole pitch of services like GeForce NOW is that you don't need a $2,000 PC strapped to your face. You need a headset and a decent internet connection. But that pitch falls apart if the stream can't keep up with what your inner ear expects. At 90fps, it actually works.
DLSS 4.5 and the frame generation math
The VR news landed alongside NVIDIA's broader GDC 2026 announcements, headlined by DLSS 4.5 with Dynamic Multi Frame Generation, launching March 31.
Here's what it does: DLSS 4.5 can now generate up to five additional frames for every traditionally rendered frame. The "dynamic" part means it adjusts on the fly, boosting frame output to match your display's refresh rate rather than targeting a fixed multiplier. NVIDIA first showed the 2nd generation transformer model for Super Resolution at CES, and this is the performance side of that same upgrade.
Twenty games are confirmed with DLSS 4.5 support, including 007 First Light, Control Resonant, and Star Wars: Galactic Racer. Many of these also support RTX path tracing, which is where Mega Geometry enters the picture.
Mega Geometry and The Witcher 4
NVIDIA announced an RTX Mega Geometry Foliage System coming to The Witcher 4 on PC. In plain terms: path tracing geometrically complex scenes (think dense forests with thousands of individual leaf surfaces) has historically been expensive to the point of impractical. Mega Geometry is NVIDIA's answer, letting RTX GPUs trace detailed foliage without the performance cliff.
CD Projekt Red getting this tech for The Witcher 4 is a statement. That game is one of the most anticipated PC releases in years, and NVIDIA is positioning RTX 50-series cards as the way to play it properly. A dedicated later in the week will have more technical details.
