Ironically, some of us get motion sickness from only 60fps (accessibility feature for blur-affected). A related blind study also showed 120vs480 OLED is more human visible in Chrome browser scrolling than some FPS competitor games: blurbusters.com/120vs480

There's pros/cons tradeoffs that depending on - Sync technology (VSYNC ON, VSYNC OFF, VRR) - DPI settings (e.g. low vs high DPI) - Game optimization (e.g. RawInputBuffer) - Your display Hz Sometimes 2000 Hz is the 'sweet spot'

Don't just test mouse lag. Test mouse jitter too. - 1000, 2000, 4000, 8000 Hz polling - Test with 600 Hz, 720 Hz, 1080 Hz display - Harmonics more visible if Display Hz *nearer* Mouse Hz - Supersample mouse Hz by 2-4x+ if prioritizing visuals - Left = 1000 Hz poll, Right = 8000 Hz poll

I miss the projector, but not its weight! 139 pounds hanging like a Sword of Damocles above my sofa, in year 1999. I did use six 400lb concrete anchors, so I had over a 10:1 safety margin. Two of us even swang a rope under the mount to stress test it first! 👽

True Multisync, up to 135 KHz scan rate. Yes I had 1080p in 1999! Even self-ISF-calibrated. Convergence, astig, keystone, bow, the kit and caboodle. Took hours to get 720p pixel perfect, 1080p usable. Practically I used 1440x810. I could run 800x600 at 100 Hz, so I loved that refresh rate.

Eventually I ran CRT 3D shutter glasses on an ASUS AGP V7700 Deluxe, a GeForce 2 GTS card running Star Wars Episode 1 Racer in full 3D glory (albiet at an eye searing 30Hz/30Hz per eye). Pod racing 600 miles per hour, 4 feet above ground, on a 92 inch screen, 25 years ago.

My unit was NEC rather than Sony. Here's Windows 98 running on it, all 92 inches of 16:9 widescreen. Before year 2000. Yes it was CRT. Projected from three 8" CRTs from inside my NEC XG135 CRT graphics projector (>12K MSRP, got used at 5.7K as B-Stock from AVSCIENCE) Blown up to 92". HD. Zero blur.

When I was barely out of my teenage years -- I used to have a three-CRT projector. Some of these Sony big-box rear projection had three tiny 7 inch CRTs blowing up to 61 inches. But some were DLPs. Me way back in year 1999:

Not necessarily. Windows updates can add TD, if it's in a collab with a display driver - Windows updates do update display drivers too and sometimes certain features/responsibilities transfers between Microsoft & GPU vendors over long term. It may have happened before. I would need to look into it.

Temporal dithering is GPU vendor not Microsoft; Also see monitor-side FRC (blue-noise/error-diffusion) and/or unbalanced inversion artifacts (chessboard patterns), not controllable computer-side. - Temporal dither PC side - FRC monitor side - Inversion algorithm (on TN can be worse than FRC/dither)

TL;DR: Lots of display progress still coming. We currently predict 2000 Hz consumer displays arriving by 2030, and 4000 Hz consumer displays arriving by 2035. Blur Busters Area 51 Portal, where I'm also cited in 50+ research papers: blurbusters.com/area51

Strobing is a fantastic solution for lower frame rates (Hello DyAc and BFI and GSYNC Pulsar and XG2431) but not everyone can handle it, too many of us get eyestrain.

Obviously, our work is cut in front of us, to fix 100 layers of the "weak links onion" of many system and hardware stutters/blurs. It's why 500Hz OLEDs currently outperform 1000 Hz LCD. Blur Busters Law dictates: - Motion blur = pulsetime for strobing - Motion blur = frametime for sample & hold

So techless nailed the ballpark retina Hz for a strobeless sample-and-hold display. A display where you want to simultaneously eliminate both motion blur AND stroboscopics AND flicker.

That's for eye tracked gazes. For fixed gaze, that's stroboscopic effects (phantom array) at that pixel step. If you go above 8K, move to a 16K 180-degree VR display with even faster motionspeeds, and you start getting numbers much closer to 40,000 fps=Hz like the techless video.

If you add GPU motion blur to fix stroboscopics: - 2000 Hz, 8000pps = 8 pixel motion blur - 4000 Hz, 8000pps = 4 pixel motion blur - 8000 Hz, 8000pps = 2 pixel motion blur - 16000 Hz, 8000pps = 1 pixel motion blur

For perfect framerate=Hz panning on 8K at 8000 pixels/sec, at perfect 0ms GtG and no jitter: - 2000 Hz, 8000pps = 4 pixel motion blur - 4000 Hz, 8000pps = 2 pixel motion blur - 8000 Hz, 8000pps = 1 pixel motion blur

Let's imagine a giant 2000Hz 8K TV on your desktop. Retina resolution, sample and hold, no blur reduction, and big. You have a 90-degree FOV of that TV on your desk. Motion blur puts pixels below retina resolution. Panning motion at 8000 pixels per second, one screen width/sec. Easy to eye-track.

This is assuming you zero out all 1000+ hardware & software weak links. Tiny list of examples: no jitter, no stutter, no GtG. GtG makes 500Hz OLED have clearer motion than 1000Hz LCD: You don't want 1ms GtG before/after your 1ms frametimes. Now, let's go extreme, for the 5-digit number.

Approximate orders of magnitude, fps=Hz: - 10 = slideshows turns into motion; - 100 = flicker fusion (Talbot Plateau) - 1000 = (at GtG=0.0) no motion blur for tiny 1080p screens - 10000 = both motion blur & stroboscopics cease to be visible for wide-FOV retina resolution screens.
