I was messing around with CRT Beam simulator via shader glass on my XL2720. My monitor can only handle a 1092 vertical total at 180hz. I have been utilizing the phosphor fade BFI to great effect, enjoying panning shots at 1920 pixels per second. This has been massive for enjoying my monitor.
Anyway ...

A question for the CHief about the CRT Beam SIm
As you know I have been enjoying using the shaderglass alpha to do a Phosphor fade BFI on my BenQ XL2720 LCD overclocked at 180 FPS. I was using it today, and thinking about something John Carmack had said during the 1st Oculus connect conference years ago.
He mentioned using sliced time warp for ...

Re: Combining XL2720 Blur Reduction with BFI (hybrid of CRT+BFI)
"Improved motion blur reduction it does not give, but it's all in the settings nuances and how it's configured."
I wouldn't exactly say that my title was red herring, hype, or "bait" that's a bit harsh chief lol. I'm not a computer vision scientist, a physicist, or an engineer. I am a hobbyist. I ...

Combining XL2720 Blur Reduction with BFI (hybrid of CRT+BFI)
I too have tested the newest version of shaderglass on my BenQ XL2720 that I have overclocked to 180 hz. With the standard strobing implementation on this monitor I can resolve 1200 pixels per second in motion, which is insanely good for this monitor.
Here are some pursuit shots that I have ...

Re: Lossless Scaling LSFG + 48 FPS video is insane
Ok, so maybe this just looks better to my eyes but I just discovered a bit of a trick.
If I am on youtube and watching a 30 fps video, I can put playback speed up to 1.20x or 1.30X and it doesn't distort the audio noticeably, but it does give me an additional 3 base FPS to do frame generation from ...

This video demonstrates the DIY perks youtube channel using an old DLP projector to get so close to near pixel level dimming for on an old LCD without the drawbacks of all recent attempts at dual layer LCD.

Re: Lossless Scaling LSFG + 48 FPS video is insane
Ok Chief I just downloaded the latest nightly build of Retroarch to try the rolling scan BFI implementation with my XL2720 overclocked at 180hz.
Holy Crap! rolling scan looks way better than global strobe, especially with that brightness adjusted soft roll off you have going on. : )
