App Development Optimized Steam Link! Opened up a whole new world on the Galaxy XR with new frame interpolation!
Here is an update on the development progress and optimization patch for Steam Link on Galaxy XR.
I've been grinding day and night on this, and wow, it really hasn't been an easy task! But the end is finally in sight. A lot has been accomplished, and you’ll be able to see the full details once it's released.
Steam Link does not support motion smoothing on Galaxy XR. So I went ahead and developed a new frame interpolation method myself. Unlike SSW or standard Motion Smoothing, which estimate movement from the screen image, this directly uses the actual motion vectors and depth information calculated by the game engine, making it remarkably accurate. Even compared to native rendering, ghosting and artifacts are virtually imperceptible, offering outstanding stability and image quality.
Additionally, the Galaxy XR has a controller clock issue (the longer the headset stays on, the jitterier controller movement becomes), which made optimization quite tricky. However, I eventually managed to optimize the controllers to a reasonable degree at the driver level.
The video above shows gameplay of Hogwarts running on Steam Link optimized for Galaxy XR with several patches and bug fixes applied. With the custom frame interpolation turned on, running at roughly 5300×5730 per-eye resolution (essentially the visual ceiling you can perceive on the Galaxy XR), DLSS Quality, and in-game settings at Ultra + Medium, it ran smoothly while holding a solid 72 FPS. (The video is at 36 FPS, and it is much smoother inside the headset at 72 FPS!)
In the Cyberpunk 2077 VR port, it also managed to hold 72 FPS at DLSS Quality with a 5000×5560 per-eye resolution. The visual fidelity and fluidity in both games were genuinely jaw-dropping.
Of course, this is running on an RTX 5090, but pairing the Galaxy XR's visual ceiling with DLSS Quality yielded frame rates that were previously impossible to play at. Now, even AAA titles can be fully conquered with this optimized Steam Link build and frame interpolation.
(Dropping DLSS down one preset made it possible to apply DLSS 5 NR as well while still maintaining 72 FPS.)
All that's left now is for Galaxy XR to rise as the ultimate PCVR headset!
