On last-gen hardware, its effects and its overall usefulness are limited.
The way it works is to enable a higher frame-rate by disabling v-sync and removing the hard-set 30fps cap. The original mod - known as Uncap FPS by Smudgey5000 - seems to be very old, and was actually designed for the original Xbox One. The news of a working Skyrim 60fps mod first emerged on Reddit, courtesy of user annathetravelbanana, and looking into it, the story behind the mod doing what it does on Series X is intriguing. Would the mod work on Xbox Series S? What about PlayStation 5? And as Fallout 4 also supports mods on consoles, I had to wonder whether there was any way to run the game at 60fps there, ahead of Microsoft's official patch set to do the same thing? The evidence looked compelling and I wanted to try it out - and once confirmed, I had a whole bunch of further questions I wanted answers to. Word emerged last week that with a simple mod, owners of the Xbox Series X console were able to revisit The Elder Scrolls 5: Skyrim, and to play it at full 4K resolution at 60 frames per second.
