Difference between ULTRA and HIGHEND

The clouds look a little better, but it’s mostly just nuisance differences. As @Sath68 said, the LOD is the main reason also for the performance impact.

If you don’t see a significant difference and get a better performance that you like, go for the high-end settings and enjoy. No need for fear of missing out :slight_smile:
