The SmoothVideo Project uses frame interpolation to increase the fps of video from 24 to 60. The results are pretty impressive. I was wondering if this could be applied to, and whether it would look good in video games?
It uses much less resources than rendering all the frames so would allow lower end rigs to render at the quality of much better rigs at some level of compromise. I know it won't be as accurate, and would slightly increase input latency as it needs to hold on to the newest frame to be able to generate and insert the interpolated one. It's not as bad as a full frame though, by my reasoning only the lag would be the interpolation time plus half the original fps refresh time. So for 30 fps it would be 33ms/2 + interpolation time.
Maybe this lag would make it unsuitable for fast past first person games, but I doubt it would be a hindrance in slower paced games.
The lag becomes lower at higher start rates, so I would think it would be certainly worth it when going from 60fps to 100+fps which improves the experience though increasingly marginally, while being extreme taxing on the system.
