This causes a visual effect somewhere between bloom and motion-blur that removes virtually all instances of high-contrast flashes.

However this pixel-by-pixel frame analysis and modification takes up additional resources, it in fact delays the showing of each new frame until each pixel of it checked, and therefore the filter is causing deteriorated performance that is especially notable on lower-end machines.

This is a prime reason why UBI should be adressing hardware manufacturers rather than game developers on this filterring? Would you agree Luthier? Bear in mind, game engine FPS may be sending (i dont know but guessing) 250+ FPS to the graphics cars, for each frame to be processed takes up a lot of CPU power, however, for the GPU to do the same would be less due to there being less frames to process. Granted the CPU on a GPU has a lower clock speed than a General CPU, but the graphics GPU is doing considerably less, depending of course on the nature of the game.

I would like to see this as an option on Graphics cards to switch this filter on for people with epilepsy and let them play, but, an option only so it doesnt interfere with people with no epilepsy. Bear in mind also, as its a graphics card option, it will then work across the board for all applications so even the windows in OS and web browsing would be Epilepsy safe
