Correct, this is what i see, (if you can see it in 4k, pixels are so small) 2.2 and 1.5 this is the same thing. As for imposters, thats usually a discussion of LOD, but even with the lowest LOD, a dot is a dot to the rasterizer. This is why if you get in a plane in VR, with 1.0 PD and no MSAA, you can see 120's come off the rail on a bandit at like 20 miles no problem (obviously you shouldnt launch this far). The dot is just visible. In 4k, this would be hard to see, because the pixels are much smaller.
