Last week, Diablo III: Reaper of Souls Ultimate Evil Edition received update 1.15, which added 4K PlayStation 4 Pro support to the PS4 version. In Digital Foundry’s analysis, they discovered that Diablo III on PS4 Pro has dynamic resolution, meaning it ranges from 1080p to 2160p, depending on the setting.

If you have a 1080p display, “this output is downscaled to 1080p for a much cleaner look.” They also noted that the frame-rate on PS4 Pro is locked to 60fps with only minor stutters, and there’s some improvements to ambient occlusion and a more impactful bloom effect.
