I have tried various upscalers. FSR, XESS , and DLSS. All of them struggle with rain. They make the rain appear streaky and much less visible.
Does anyone know of a solution to this?
I feel like there should be a way to tackle this, perhaps by excluding translucent objects from the upscaler or something.
I feel like the AW2 team did a video on their rain system and they addressed exactly that problem (how to render rain with upscaling +path tracing in real time), so I’d try to look for their video and see what solutions they found. It obviously worked quite well given how effective the effect is, but it required some special work from what I remember.
