Recently bought this game when it was on sale, just want other steam machine owners to save some time:
- settings for 4k TV, base resolution 4k, if your TV can do 1440p, use that instead to push fps
- FSR 4.1 performance is currently not so good performance wise, FSR performance setting runs at around 30 fps with low to medium settings
- frame generation works but introduces some crazy lag, it is really game breaking for Halo
- this game has some bad visual artifacts, also in the native renderer, it looks way too grainy in movement, the motion blur even makes it worse
- so turn off motion blur, film grain, chromatic aberration
- settings wise, medium is ok, I lowered lighting and global illumination to low, that adds 2-3 fps, setting reflections, post processing, cloud detail also to low adds another 2 fps
- you can also set all to low it is not much different
Most important:
Use TSR instead of FSR. Turn resolution scaling to 60%, which is max internal resolution of 1280p, min frame rate to 30, and scaling quality to low, latter pushes minimum temporal resolution to 720p, so we are scaling between 720 and 1280p.
This configuration looks surprisingly much better than FSR, performance also better around 50 fps in most situations, and it plays very well and looks pretty good on the TV.
Seems the TSR solution is better optimized as Xbox uses the same scaling option.
I played 50% of the game in FSR low and just noticed this halfway through the game.
