Can DesktopBFI have the anti-retention algorithm, like CRT Beam Simulator on Shader Glass?

Ask about motion blur reduction in gaming monitors. Includes ULMB (Ultra Low Motion Blur), NVIDIA LightBoost, ASUS ELMB, BenQ/Zowie DyAc, ToastyX, black frame insertion (BFI), and now framerate-based motion blur reduction (framegen / LSS / etc).

Can DesktopBFI have the anti-retention algorithm, like CRT Beam Simulator on Shader Glass?

Shader Glass BFI seems very promising, but for now... its unusable for me. I tested and had absolutely no problems with flickering, unless using 100% of my gpu, but even then, its unusable. It have an enormous problem with the capture stutter, which most of the time it just doesnt seem to sync correctly and stutters a lot even when turning shaders off, and, even when it doesnt stutter, sometimes it seems to not sync correctly and it doesnt work properly when used together with hardware level strobing, then it starts producing double images.

On the other hand... DesktopBFI works pretty well for me, and it works well in many ways.

Im using the Wehem fork (github/wehem/desktopbfi) where: it doesnt desync, it allows me to always use half of my refresh rate, so its not locked at 60 fps gaming. i can set my monitor at 144hz and game will run at 72 fps with bfi. its not a "rolling scan" bfi, but full black frame insertion one, which provided by far, better results here than shader glass and CRT beam simulator. at least for me.

i could achive 1ms of persistence at 280hz/140fps at 960pixels/sec with Desktopbfi and 2ms with 120hz/60fps with DesktopBFI.


Please, dont take me wrong. I love both, i love crt beam paired with shader glass, but having options is nice. Having a way to use full black frame insertion instead rolling scan is nice, because even when we "turn off" the rolling scan bar on shader glass, if you record it at slow motion, it still rolling scan, your eyes just can see it anymore in real time.

I wish i could program and add the anti-retention algorithm to DesktopBFI by myself, but i have no idea how to do it.


For now, if i use Shader Glass, it will stutter or give me double image effects. If i use DesktopBFI, it will cause retention and probably "burn-in" in the long run on my monitor... I wish we could just have at least the option to use DesktopBFI because for now, its working and even when shader glass and crt beam gets fully functional, it still being a different approach to BFI that in my opinion, is very welcome.

Share your opinions and toughts here. Mine is that having both of them working (specially desktopbfi that for now just needs the anti-retention algorithm) would be pretty nice for the motion clarity community.
