I should perhaps clarify for precision. The last image is 179.something degrees. Of course 180° exactly is literally impossible.

170°, 175°, and 180° in rectilinear rendering respectively.

As far as I'm aware, the OpenXR API and most XR standards are built around rectilinear camera projections to support functions like compositing as well as regular/late stage reprojection. Does anyone know of any existing XR support for non-rectilinear rendering? I'm looking to render native in VR.

For a long time, the inherent distortions of rasterized rendering has bugged me, especially in XR. This limitation has perpetuated into ray/pathtraced rendering as well despite the opportunity for non-rectilinear camera projections. I'm writing a forthcoming article exploring alternate projections.

Vint has been available on Steam for a year today! Thank you to all of my great customers who help support my work on this software. In this last year, I've added new platforms, major features, and regular updates. Next on the roadmap is Linux. For the anniversary, Vint is now 30% off on Steam:

120Hz is definitely the minimum but I'd really recommend more than that on the display side. If, for example, you're running at 60FPS, you generally want at least a three or four times ratio so 240Hz is what I'd recommend for most. A two times ratio is less compelling but it's easy to test.

Vint is also on sale alongside this update. In addition to Vint's UHQ interpolation, it also has a wide range of different strobing options. Try it out and see if you like the improved motion fidelity Vint can offer. Steam makes it easy to refund if it's not your jam. youtu.be/iZLhlFFI0f8

Thanks Mark! It's great to have so many new options for flicker and framegen these days. It is, however, critically important to understand what they're doing and when to use them in order to get a good experience. Tradeoffs abound.

Deciding how to bust display motion blur? BFI? Strobing? CRT? Framegen? Organic? Etc? Users choose! William writes about blur busting methods including flicker-based (BFI, CRT, strobing) and flickerless (framerate-based, framegen-based, etc)

I just published an article on Blur Busters comparing flicker and frame generation and when to use them. The article dives into film multi-projection, FPGA video processing, and all the many different flavors of lightweight to high performance interpolation. Let me know which solutions you prefer.

Yes, Vint uses MPV for video playback and has full HDR (HDR10/10+/DV) support plus great tonemapping as well as support for RTX Video HDR. Offline transcoding doesn't support HDR at the moment but may be added later. Vint with MPV also supports all sorts of scaling like RTX Video Super Resolution.

Thanks Chief! I would love to see Digital Foundry make a foray into this topic. Motion fidelity is far too often set aside in favor of static image reality. There is a whole collection of different new framegen and strobing options that make both far more viable for general use.

If you have purchased and downloaded Vint and want to know how to use it, I have some documentation here: www.willse.me/VintDocs Vint has some tooltips in the interface. Finally, if you have any issues or questions feel free to use the Steam forums or email me for support at VintSoftware@gmail.com

LSFG is more comparable to FSR or DLSS 4.0's framegen. Vint is more comparable to MadVR's 'Motion AI' feature: youtu.be/nDoAXb5su3U Vint works great with movies, TV, or youtube content. Vint's trailer shows how well it can work: youtu.be/U5lZbp6H6Q0 3/5

TLDR: Lossless Scaling FG: Made for games, lower quality output image, runs fast, requires higher source framerate, has substantial artifacts. Vint: Made for videos (local or streamed), higher quality output image, runs slower, handles very low source framerates, has far fewer artifacts. 2/5

William Sokol Erhard @williamsokolerhard.bsky.social · 21/03/2025

Vint however uses machine learning RIFE interpolation (amongst other BFI/strobing options) to produce very high quality smooth video from even very low framerate (24fps or less) videos. Vint uses high quality more computationally expensive process that is accelerated with Nvidia's tensor cores. 2/5

William Sokol Erhard @williamsokolerhard.bsky.social · 21/03/2025

Hi LosCV29, Thanks for looking at Vint. While Vint has some base similarities to Lossless Scaling, LS framegen is far more focused on smoothing out small changes in low latency on already higher framerate (60+ fps) video using simple optical flow which can produce substantial artifacts. 1/5
