Forza Horizon 5 on the Pro:
Quality Mode : PS5/PS5 Pro are virtually identical at Native 4K and settings with Pro adding RT reflections. Locked to 30fps.
Performance Mode : PS5 is 1872p while Pro is Native 4K. Essentially base PS5 Quality Mode at 60fps. Preferred mode to play in.
That's basically what was the point, the performance mode is better than the regular PS5, you get 4K mode at 60fps while on the PS5 you're playing at a lower resolution. The "quality" mode on the PS5 doesn't have RT reflections. Many games do this.
