The Elder Scrolls 3: Morrowind has received a much-needed upgrade thanks to Xbox One X. Digital Foundry reports that the classic Xbox RPG shows a massive performance difference when played on the Xbox One X.

The game runs at a relatively stable 60 frames per second on the console, making it one of the fastest Elder Scrolls games available on consoles. The original had an uncapped frame-rate, causing stuttering and inconsistency. The backwards compatible emulator smoothes that problem, though it does still hit occasional hitching and dips into the low 50s FPS in dense areas like the town of Balmora. It also adds near 4K resolution, a big upgrade from the original output of 480p.
