In Elder Scrolls Online consoles will receive a significant share of graphical improvements and performance improvements along with Update 31. These improvements followed the release of the ESO Enhanced console, as a result of which the MMO received an improved version for current-generation consoles, including the Xbox X|S series and PS5.
However, it seems that the work on performance and graphics continues. Dynamic resolution scaling will be introduced, while the engine will still run at 60 frames per second. With update 31, the resolution will have the ability to scale depending on the load. This means that the Xbox Series X and PS5 will have a resolution from 1080p to 4K. On the Xbox Series S, the resolution will range from 1080p to 1440p. HDR was also discussed with consoles configured to receive a new HDR mode with preserving shades. This should match the appearance of the SDR, but with an increased HDR range. This option will be a switch.
Speaking of PCs, multithreaded rendering appears in the form of a beta version. If you have a limited processor in ESO, you can switch this option, which should theoretically improve performance.
