I think there is wisdom in that. I admit to have initially looked at it from that comparison. However, as another member posted, it is a striking difference after downloading the 4k uncompressed version. Then review the vanilla FO3 and Skyrim.
Granted, it's not pushing the realism envelope as much as others but it's a very acceptable palate for vanilla.
I first noticed the lighting was nothing short of running an ENB looks very good. I thought the art style was well done and a close up of curves were not blocky. At first glance, it looked like they were just missing a final layer of detailed texture. Once the 4K downloaded the textures were there.
As much as the webs have been slamming the graphics, a poll was recently taken in the forums about what element you could do without if you had a choice between various content, customization, characters and world space. Interestingly, as the poll was developing into the third day, it showed that most people would give up graphic fidelity. Alas, the poll was thought to be misguided and thus, disrupted and parts deleted by the OP.
I look at it with the same limitation decision. I accept having less than CGI quality realism to allow for more content and complexity. I accept a base game that meets the requirements of a broad range, accompanied with tools to make improvements tailored to my system's capabilities.
