It sounds like Volition’s Saints Row spin off Agents of Mayhem will be supporting the PS4 Pro, with enhancements for the game on Sony’s superpowered PS4 announced. The enhancements will, as is always the case, strive to deliver enhanced visual quality.
In this case, players on the PS4 Pro can expect anisotropic filtering, a higher level of detail for the textures and shadows, uncapped framerate that can go as high as 60FPS, and 1080p resolution. The amount of vehicles and pedestrians on screen at once will also get a boost on the PS4 Pro.
Apart from Volition’s action game, Sine Mora Ex and F1 2017 will also be getting PS4 Pro enhancements; in the case of the former, players can expect better particle effects, and a resolution up to to 3840 x 2160, with the game itself running at 60 FPS. For F1, shadows and reflections will be more dynamic, and the game will support HDR output.
So, yes- it sounds like all three games will be getting some good use out of the extra juice present under the hood of the PS4 Pro.
