Digital Foundry writes: “It’s all a bit baffling. Patch notes describe a 4K 60fps performance mode, a 4K 30fps/40fps quality alternative (depending on whether you are running on a 60Hz or 120Hz display) and a 1440p ultra settings variant. This seems to have been delivered for PS5, but there are problems with Xbox Series X. The performance/quality mode toggle does not work. The evidence suggests that Series X is locked to performance mode only. Disabling this on Series X doesn’t seem to change anything – and visuals are notably cut back not only up against PlayStation 5’s quality mode, but also against the Xbox One X 4K 30fps back-compat variant you could play last week.”
