I've now watched the full DF tech review of the game, not just the PC section I watched yesterday. It's clear that the game has incredible level design, detail and atmosphere and that ray tracing plays a large part in that for shadows and reflections, but most importantly the ray traced transmissions option which gives skin and flesh transparent translucency making it look like real flesh from rendered CGI. I know many folks don't care much for ray tracing but games like this and Cyberpunk and others it really makes a difference and I value those enhancements, which DF shows really well side by side.
Likewise in games like Cyberpunk the RT reflections and shadows made a difference as did the RTGI, but we had DLSS on that so could get over 60fps with RT enabled.
If they patch up the game so FSR isn't broken, and the single threaded CPU limitation is fixed too, then I'll re-buy it.
