First 15 seconds of the link you provided the developer of Q2VKPT Christoph Schied, says that nVidia placed extensions on top of Q2VKPT.
There are some parts that aren't path traced, the volumetric sun light or something.

Path tracing doesn't care much about the scene, be it a simple indoors Quake or something else, sure BVH cost will be higher with a more complex scene. Materials used however do have a large impact. It runs slow even on RTX so on GTX... good luck getting 1080p60 on 1080Ti.
In some ways I think the Q2VKPT was made to look closer to original, contrasty look, clipped blacks, not much light gets bounced, ... one would have to rewrite more to get it look what some may expect from path traced "movies".
Q2RTX seemed to look a lot different. I think it's a waste of time to mod the Q2VKPT since Q2RTX will be made public eventually.
