First test with RT-enabled BF5 are online. Either the game implemantation is abysmal or the RT cores are far too slow for proper gamplay. FPS are going down to 1/3rd with full RT effects enabled and still halved with low implementation. Power consumption of the RTX cards is dropping as if the standard gfx core are waiting for the RT cores to finish their job.
At the moment it looks like a shiny tech demo but unusable for gameplay. At least the raw power for non-RT games under DX11/12 is very good but still not justifying the abnormal price.
