TAA: Temporal Antialiasing

I'd like to suggest adding temporal antialiasing to the game.

FXAA, MSAA, and others are not good enough and cost too much in CPU/GPU.

I'm not sure what visual benefit TAA would bring to an isometric video game with no camera panning. I do get the point of the ATAA algorithm though probably the best looking AA I've seen of recent years was id's TSAA.

A lot of games use MSAA + TAA in attempt to snuff out the blurring TAA causes but it's even more performance cost. At any rate we'll have a new engine soon with Path2. With a good engine it will likely cost less to run MSAA + TAA over options we have now.

I'd be happy if just more games supported Vulkan since I pretty much get +3-5 FPS every time.
