Just a reminder that we're looking for alternative ways of framerate-based motion blur reduction.
I'd like more ideas of non-framegen based methods of motion blur reduction!
Assuming GtG is as close to 0 as possible (e.g. OLED)
4x framerate = 75% motion blur reduction
10x framerate = 90% motion...
I apologize for bumping one more time, but I need to add yet another famous Blur Busters referee call-out.
Is it apples vs apples though?
The youtubers are having to use bigger zoom ratios. Smaller/thinner the distortion halos during improved framegen -- can simply look like extra...
Even if 90% less than DLSS 3.5, I also confirm this too, that DLSS 4 Transformer+framegen doesn't fully fix warping or ghosting but yeah the YouTubers are starting to zoom and slomo it to convert the thinner/smaller halos of ghosting (incrementally minor) into individual big frames of warping...
Different humans are sensitive to different artifacts.
Whether by pickness, by preference, by biology, by training & skills, and/or by comfort.
And different lineitems are minor or major to others than you, etc.
Tearing? Turn on VSYNC and tolerate lag.
Minimum Lag? Use VSYNC OFF + ultrahigh...
Disambiguation required.
What they call "interpolation" in 2025 is very different from 2010-era "interpolation".
I don't like Grandpa's Sony Motionflow TV interpolation but the Transformer model with framegen is about 0.1% of the artifacts of 2010-era TV interpolation.
More ground truth is...
I use Hollywood Filmmaker Mode and 24fps for all my movies.
Remember I used to work in the Home Theater industry, having had past contracts involving classical high end home theater equipment RUNCO, Key Digital, and Faroudja.
I released the world's first open source 3:2 pulldown deinterlace...
That's why I am an ardent big time advocate of base frame rates above flicker fusion threshold, for this type of artifact.
There's much less time for deviations + the oscillation between rendered and estimated frames oscillate to simply extra persistence blur (ghosting effect when warping...
Depends. Not always wasted. If you have an OLED and use Transformer, then the benefits:drawbacks ratios may flip, if you get more motion sick from motion blur problems or motion sick from low frame rates. 30fps upconverted to 120fps with a little help of Reflex2 lagless mouse look, can be a...
I predicted large ratio framegen in 2019 with my "Frame Rate Amplification Technologies" article on the Blur Busters website, which is now pumped to Page 2 of /area51/ url appended to the blurbusters url..
Look at the year.
April 4th, 2019.
While not perceptually lagless or lossless yet...
FYI to those who is unaware, the third party framegen engine Lossless Scaling (LSS) just recently unlocked framegen ratios up to 20:1.
It doesn't have as much access to ground truth (vectors etc) to de-artifact large ratios, but for those pimping 4090's a wee bit longer, it can be an...
The new DLSS 4 multi-framegen is much better framepaced than the DLSS 3.5, and I saw zero VRR flicker on the 480Hz OLED I saw framegen in. Frametimes were consistently less than 5ms on some of the demos (the demos that maintained north of 200fps with RTX ON), staying above the OLED VRR flicker...
Yes, I recommend base framerates above flicker fusion threshold, depending on how fast your display is.
That means pre-framegen framerates of at least ~60fps on LCD, and at least ~80fps on OLED.
This forces oscillating artifacts (framegen-vs-nonframegen) to be hidden by its own blur...
Main stream visibility need geometrics and GtG=0.
Such as 4x differences (e.g. 120 vs 480) and GtG=0 (e.g. OLED)
You gotta VHS-vs-8K it temporally, not the mere equivalent of 720p-vs-1080p much like 120Hz-vs-144Hz, or 240Hz-vs-360Hz LCD (1.5x diluted to 1.1x due to nonzero GtG).
Pro users and...
Yes, scanning backlights and edgelights are a thing! BenQ has done an excellent job with DyAc over the years, as one of the best competing strobe backlights versus NVIDIA ULMB2.
However, NEITHER can simulate a 60Hz CRT, like either my XG2431 or my CRT simulatorl They have a DRM firmware...
97 KHz horizontal scan rate? Ah yes, that's a toughie, interlaced DOES help a CRT. It's actually possible to get 4K on a CRT achieved via interlacing means, even if the pixels are not resolvable.
Wish it was simple as doing 4:2:0 over DP. Some drivers still have a 4:2:0 mode that saves 50%...
You can also instead emulate interlaced, too.
I already do it at www.testufo.com/interlace -- zoom your browser 300-400% to get it closer to retro-style resolutions, then go to full scren and you can really see interlacing in action.. And there's an interlace shader available for RetroArch...
I'm still trying to get one locally (Toronto area). I've only had FW900 loaners, and I've given up trying to own one -- either they're too far away and freight shipping is a fortune -- or too expensive locally.
They will stay expensive. The number of working FW900s will decline.
One of the...
If a 1% white window stays the same as a ~50% white window on your OLED, then you probably will be fine. HDR400 is quite limited, but it is also not too difficult.
You just have to adjust GAIN_VS_GAMMA, then it will eventually wiggle under the window size of linearity (e.g. ABL not kicking...
Yes. Slip. I had only 3 hours sleep.
I meant plain Gamma 2.2 or 2.4 sRGB -- you can configure the curve.
I need better access to a linear HDR APIs untouched by display distortions, to solve the banding problem in HDR. On some displays it works well but on some other displays there is banding...
Yes. We are talking now.
It may, however be a choice between filters or scan emulation rather than both - due to limited memory bandwidth. Keep tuned.
But theoretically filters and scanning may be concurrently possible at lower 720p and 1080p resolutions due to the refresh rates needed for...
Just want to give everyone a heads up about my new open source (MIT license) CRT beam simulator shader for high-Hz sample-and-hold displays.
Here's the github source code, and shader toy (240Hz demo version, flickers too much at 120Hz), or my article on blurbusters website.

"Actually..."
While this is true for classical BFI, there's methods to smooth it out if you have large native:simulated Hz ratios available, as well as fade-frames (or per-scanline in the case of CRT simulator), like the time-dimension version of antialiasing.
My new CRT simulating shader went...
While 1000 is a realistic plateau, it's not really the endgame as retina refresh rate isn't till roughly 20,000Hz (for 180-degree FOV 16K resolution, aka VR). Higher resolutions and wider FOV amplify refresh rate limitations dramatically, as does GtG=0 (e.g. OLED instead of LCD).

Another underrated part of curved 45" is when your eyes are getting older -- and your eyeglasses prescription. The curve means your eyes are about the same distance for the whole radius. This is less strain on the range of your reading glasses.
I can still go flat though when it matters --...
If you can maintain that framerate -- then you're going to get a bigger upgradefeel. I do generally recommend most mainstream people upgrade framerates & refreshrates by at least 2x, for them to feel it was worth it. Geometrics are the win in the refresh rate curve. Most games will end up...
The first ones will be on the retail market much less than half that timespan. You saw the TFTCentral Roadmap.
Keep in mind the 4K 240Hz OLEDs have a fallback 1080p 480Hz mode, so you'll have your 480Hz OLED inside the window of year 2024. The dedicated 1440p 480Hz panel isn't roadmapped till...
For the PPI folx here, a big boom 31.5" sized 4K 240Hz OLEDs are coming in the next 12 months.
The first will be exhibited at CES 2024. If you want to maximize your upgradefeel in ppi, that's the one to watch for!
For me, my motion sensitivity means prefer a "slightly bit lower ppi" simply to...
Get the 480 Hz OLED when it arrives.
WOLED's are also fine for office use nowadays; no need to worry about burn in as much as one used to. Even some LCDs degraded faster according to RTINGs. I've been Visual Studioing on a prototype 240Hz OLED for 1.5 years now.
It's also better on my eyes...
I remember those lovely Kuro's.
The upcoming 480 Hz OLEDs will finally produce quite some interesting advanced-rolling-BFI possibilities. I have an offline prototype of a TestUFO CRT realtime electron beam simulator (using per-scanline-brightness lookup tables, rather than realtime shader...
Plasma displays had their day, but with a theoretical 600Hz OLED, I could software-simulate those subfields. Though HDR subpixels may not pulse as brightly as plasma phosphor, the feel would be similar. It would be theoretically possible to duplicate the subfield in an emulation. However, I...
Software BFI does work on LCD on the Retrotink 4K. It just works so much better on an HDR-capable OLED, though. The nit-boosting trick for BFI works much better on OLED. But software BFI on a good quantum dot backlit LCD actually looks decent-ish (except for LCD greys), a little bit more...
Ooops, I quoted the wrong LG model! Yes, I'm talking about the other LG OLED models limited to no less than 8.3ms persistence during 60Hz BFI.
For this specific one, it's likely roughly similar (due to limitations of external BFI injection can not be less than refreshtime), but the bonus card...
My Retrotink 4K prototype here, as a box-in-middle BFI, can now even out-BFI even the LG firmware BFI.
I get a brighter BFI picture on my OLED than the firmware LG BFI because of the SDR->HDR converter + nitbooster trick!
And I can make my 240Hz OLED 4x clearer in motion for 60fps material...
Wrong.
As well-intentioned as that assumption is, based on yesterdays press release hype, it is best not to assume on tech you have not seen. 😉
OLED looks better than the SED prototype that had worse artifacts than LCD.
Digtally-addressing these things often required compromises such as...
Sadly, no.
There are some Sony's with HDMI input (e.g. Sony KD-30XS955), none of them better than the 900 series AFAIK as they are lower dot pitch. There's also the widescreen Sony PVM/BVM, the broadcast monitors, though they were generally designed to handle TV brodcasts rather than computer...
Yes -- there is a large factor of personal preference involved too.
The large-ratio frame rate increases (made possible by DLSS3+) is an alternative motion-blur-reduction substitute to flickery BFI/strobe/ULMB/DyAc -- at least for casual gaming.
If you use an OLED display, it's becoming...
Depends on your goal persistence. It's probably going to be a fantastic sweet spot for most users (e.g. average retro users)
For moderate and slower scrolling at low resolutions like Super Mario, 2ms persistence is perfectly fine. But for ultrafast scrolling ala Sonic Hedgehog, you'll want a...
Sounds about right -- 1000 Hz OLED is about ~2027.
You can do a real-time 60-100Hz CRT electron beam simulator with that brute refresh rate, utilizing HDR nit surge headroom too. Complete temporal beam simulation in 1/1000sec timeslices.
Rolling scan, phosphor fade, low persistence, etc. All...
4K progressive-scan on a CRT! Nice to see, even if it's not resolvable.
I knew it was possible to do 2160i in the bandwidth of 1080p if you jumped enough hoops -- but 2160p I haven't seen anybody do that at full 3840 wide.
You must be using 200-300% DPI zoom at the moment!
Try testing VRR on...
