And the use of the pipes is a novelty, as is the running and sliding(Same as wolfenstein:no). Everything else looks really nice so far.
not changing in the rhythm of the fire flickering. Which is strange to look at the torches and see the fire flickering but the light scattering effect on the wall is constant and static i.e. But here, the lightning information is stored in the megatexture and is static. Only one thing that is a bit distracting, i think even the old return to castle wolfenstein game had dynamic lightning with the torches. I have 38fps to 40fps at 1080p with 2xAA and most options to high or medium.
(Old blood even has special cuda optimizations in the graphic options menu). Although the wolfenstein games seem to favor nvidia gpu based cards a lot.
