Simulating CRT on a smeary 120 Hz LCD doesn't sound good to me.

Only the latest super high refresh OLEDs are approaching that capability and the software is not done. Nobody is simulating the rays right now. Pretty niche, so progress is slow.

That’s simply not an issue. I’m not trying to simulate a CRT, I’m trying to avoid nausea inducing sample and hold blur. Which BFI does a good enough job of. Sample and hold displays including OLED are to me just both smeary messes at anything below 240hz.

I also use BFI with my OLED and sure, BFI at 240hz is better but it’s not available to me in a handheld.

I don’t perceive any flicker at all, not even on my CRTs and never have. But oddly, I found motion blur induced by sample and hold displays induces nausea in my system. I’m really sensitive to it for some reason.

If you're looking to simulate a CRT that's not a problem because 50/60 Hz CRTs all had horrible flicker. We were just used to it.

If you see one now you'll see how bad it is.
