raytracing is possible, i have tried it in other games (except my card is bad for it, but more to turn it on to see if it works)
the 9070 is extremely new and might be lacking raytracing support as of right now, drivers were just hooked into mesa not that long ago and freedesktop (the maintainers of mesa) are currently migrating to new servers so no fixes will be available for a bit less than a week.
(could also be that the game is doing something weird, i would suggest to try it also in a different game to see if its a game issue vs driver issue)
