Sad state of affairs, Saints Row was quite enjoyable.
This saddens me even more (DF review)
As it stands now, the 1440p high FPS mode is the best of a bad bunch, and works well enough with a VRR display.
Just as I feared, VRR as a crutch to mitigate unstable fps. None of all the modes can maintain a locked 60 fps and there's no 30 fps cap option. One to avoid.
More crucially, the five modes offered on PS5 and Series X do add flexibility to tailor the experience, but fundamentally this is a DIY approach to optimising a game. It hands responsibility to the end user, and no option is really 100 percent ideal.
Play it on PC, don't bother with the console version, no point.
