TAA is a crucial tool for developers - but is the impact to image quality too great?

For good or bad, temporal anti-aliasing - or TAA - has become a defining element of image quality in today’s games, but is it a blessing, a curse, or both? Whichever way you slice it, it’s here to stay, so what is it, why do so many games use it and what’s with all the blur? At one point, TAA did not exist at all, so what methods of anti-aliasing were used and why aren’t they used any more?

    You must not notice aliasing and shimmering then? Most find it very distracting to see everything flickering and shimmering and stair step with the slightest motion.

    And ray tracing really depends on the game, implementation, and hardware. Ray traced global illumination alone fixes the classic video game look that stems from rasterized lighting errors (light leaking, default ambient light, etc). It is the future for high quality games even not photo-realistic ones. Its expense is offset by both reconstruction and improved hardware. You wont be able to avoid it forever even if you want to.

      It has gotten much better in the last 7 years. I will say that I usually test 1.5× or 2× my resolution if possible, which can to be less taxing depending on the engine, as I’m always trying to eek out a little extra on my 970.

        2x on a 970? I struggled with my 970 at 1440p low-medium settings until i got the 3080. Often had to put scaling to 1080p. And that was on “last gen” titles, cant imagine still trying to limp that thing along nowadays, despite as much as i loved it.

          Depends on the game, but I don’t usually pick up current gen for a bit. Unless you count Switch Emulation?
