2.03 Decrease texture size - does this improve graphics or improve performance?
It improves performance, by reducing quality of the textures.
6.07 Forced texture reload/6.08 enable managed textures
what do these do?
No idea, so just keep them default
In the right hand column where we select to enable or disable a setting do I click 'Enable' to enable? or do I want 'Enable' to be showing? Sometimes it seems like I have to 'Enable' an option to 'Disable' it and vice versa.
The wording is strange, so think of it as more True/False or Yes/No. So if it says "disable something" and you choose "Enable" it will be *disabled* - make sense?
3.02 Disable Ambient
Do I click 'Enable' to disable Ambient?
To disable Ambient sounds you *enable* this
2.13 Remove insignificant objects.
If you want to improve performance by removing some "unnecessary" details, like destroyed parts of vehicles, dropped rifles/helmets etc, you *Enable* this.
4.02 Show blood
in order to get blood to show in battles I had to click 'Disable' in the settings menu, I am sooo confused.
This should be Enabled to show blood so not sure what happened there. Try it with Enabled?
Basically, the settings menu messy and I keep stuff mostly at defaults, except change a couple of things like control allies and disable the excessive bloom.
Rule of thumb; if you don't know what it does, keep it at default 8)
One thing I'd wish for is to have the settings retain after I apply patches, it's a mess to reapply if you make a lot of changes
