OCC published Darksiders III Performance Analysis
A quote from the article:
Darksiders III does not really have any special technical characteristics to it to be concerned with, like support for multiple APIs or special technologies like NVIDIA's RTX or DLSS, which is good if only because the graphs should not be so crowded. There is a 62 FPS limit active by default in the game, but it can be easily changed by editing an INI file, and you can find the instructions on how to make the change at the game's PC Gaming Wiki page. I raised the limit to 300 FPS, which I felt would be high enough to let the GPUs I have reach to their limits.Darksiders III Performance Analysis
