I tried this on my client system (single player, but system graphics card is so low end I have to play in windowed mode and very low video settings).
it worked well. For the first time in forever I saw 50-60+ FPS (in a forest, with a small poi nearby).
some info:
- I read the FPS benefit may go away in some situations (large horde, etc). Personally: don’t care as I see the benefit during normal game play more often... however: because FPS gained, I started turning “up” my video settings (because why not?). At some point later in the game my game froze. I run a lot of mods so it’s not vanilla, but it normally doesn’t freeze up. But I don’t have a lot of data/testing to pin it down, just more of a “hmmmm” because maybe I turned up video settings and the “benefit” conditions hit and it was too much load. So, my current recommendation: leave other video settings alone that worked before you messed with this setting IF your settings were set very low to begin with to make the game playable.
- if you go into steam game properties and “validate local files”, the boot.config file will be overwritten with defaults, removing this settings change.
