Should demosceners consider buying a RTX card when renewing the GPU ?

Will we see "RTX only" kickass demos/intros soon ?

arent all raymarched 4Ks etc pretty much "RTX only" already? :P

@Pablo : I am unsure if your answer was serious or not :)

AFAIK RTX will not help directly for raymarching, because it can only calculate intersections between rays and triangles.

what about this : the raymarched scene (which is a function that return closest distance to an object) would be converted once to triangles (eg : using marching cubes). Then to raytrace agaist those triangles to know where the closest collision will be. Then to start raymarching from that point (for extra performance).

Tigrou: OTOH, many demos require top-of-the-line GPUs - which eg. I have no money for.

porocyon: from what I understood the gains are minimal because the first steps of raymarching are actually fast enough, it's only when you get close that they start shrinking a lot.

xernobyl: I'm not talking about raymarching, but demos in general.

I'm aware. It just annoys me that the hardware is quite pricey.
