With Destiny 2, it’s even more obvious that the game isn’t running at the highest settings. On a Chromecast Ultra, a “4K” stream looked closer to 1080p, and my colleague Tom Warren and I swore that the 1080p streams we were getting in the Chrome web browser looked more like 720p.
Initially, Google told us that it was using the highest-resolution, highest-fidelity build of Destiny 2 available. But Bungie later confirmed that our eyes weren’t deceiving us. “When streaming at 4K, we render at a native 1080p and then upsample and apply a variety of techniques to increase the overall quality of effect,” a Bungie rep said, adding that D2 runs at the PC equivalent of medium settings. That explains why the Xbox One X build, which runs at a native 4K and with higher-res assets, looks so much better than Stadia.
