Blur Busters Open Source Display Initiative – Refresh Cycle Shaders

So this a new method that simulates a CRT and genuinely reduces motion blur on any type of higher framerate displays, starting a 120hz. But it doesn&#x27;t dim the image like black frame insertion which is the only current method that comes close to the clarity of a CRT. But it also simulates other aspects of CRT displays, right?<p>Can you use this method just to reduce blur without reducing brightness, on any game? They mention reducing blur for many things other than retro games in &quot;Possible Use Cases of Refresh Cycle Shaders&quot; but does reducing blur in a flight simulator also make it visually look like a CRT with phosphors?

I do not understand at all what this is talking about or why. Is it some elaborate joke?<p>Don&#x27;t visual effects people go to lots of effort to add motion blur? Why would you want to remove it?<p>Why are they trying to simulate old CRT displays?<p>Can someone explain what this is about?

We need display manufacturers to provide a refresh cycle that is agnostic of the incoming signal hz sent down the cable AND to either provide shader support (ideally) at the displays hz OR to implement this shader.<p>There really is no need for an expensive RetroTink if we had this. Some manufacturer must be able to do it and the rest would follow.

With about half of the screen is black, can it also boost FPS by not spending GPU time on pixels in those areas if integrated deep into engine?

Does all this shader really get around is the problem of display inversion?<p>From Gemini: &quot;Display inversion is the process of alternating the voltage between positive and negative for each pixel on an LCD screen to prevent damage. This process is called polarity inversion.&quot;<p>If display manufacturers knocked that on the head for certain scenarios then surely we could just have a simple block of horizontal screen scrolling down the display at high refresh rates?<p>Phosphor fall off as far as can be seen in Slo Mo Guys is quite a small effect not on the scale of this shader.

Cycle refresh shaders where someting my last team really nailed. The key challenge was during the day there is a lot of sun. Adjustments can be made to the location, it really pays dividents.

Does this mean that the original duck hunt gun might work again?

I&#x27;d buy a new TV or monitor for this feature alone.

If this is proven to work for 99% people and high refresh displays become cheap GPUs could optimize for rendering just a sliver of screen at a time.
