Ray Tracing Technology

[The Hero of Orlais]

We got real time ray tracing in video games now, but does it only works with RTX 2000 series ? does the previous graphics card became obsolete with this new tech ?

Needs hardware support, thus only works with RTX.
it will take a few years for support for raytracing to spread past the few AAA titles.
in the mean time, old 1080's can still push oldfashioned non-raytracing pixels just fine, as before.

Intel is plotting their own GPU, will that supprt RTX tech or something else?
AMD had hairworks, it looked nice, didn't really take up all that well. New AMD cards wont likely support RTX as such (Nvidia thing) and will most likely implement their own. Will differences on Nvidia/Intel/AMD implementations shatter the playfield where few games are X exclusive, some Y and some Z? possibly.

Will it all be "under the hood" in DirectX and game devs don't need to care? just click on "make pixels pretty checkbox" probably not.

Until actual release, benchmarks and other company solutions are reviewed, it's hard to make speculations. I would say that no, old fashioned cards are not out yet and can last the two to three years that it takes for RTX to spread. At that point, there will be new and shiny cards out there for picking.

Every other GPU before the RTX 20XX Series are also able to use Ray tracing but they are too slow to do it in real time.
There are only 11 Games announced that will support RTX. Therefore the current 10XX Series wont become obsolete since they still offer a good performance in games.

Ray tracing is not exclusive to Turing (other gpu can also do it) but turing have dedicated hardware that makes ray tracing a lot faster. But i see people also get the wrong idea about this whole thing. We are not going to get full ray traced games. What nvidia try to push right now is hybrid rendering. For gamer the benefit will not be that big. Using ray tracing does not suddenly make our game to be photorealistic. They can still pretty much look like current games. But the biggest benefit will be for game developer. With ray tracing they no longer have to use tricks here and there to mimic how real lights reacts to the enviroment. This way they can clean their game engine of unnecessary codes that can make things complicated when optimizing performance and ironing out bugs.

aw sux, thanks for the answers guys
