VTO - Urban View Distance

v 1.0.6 - by Reezo

[www.paypal.com]


# DESCRIPTION
This mod adds new, dynamic view distance management based on the proximity to urban areas (from small towns to big cities) in order to alleviate the heavier workload that urban areas impart to the Arma 3 gameplay. Via a hotkey (default: User20), players can fine-tune their view distance settings and generally improve FPS and performance in otherwise CPU-intensive areas of a map.

Parameters:
- MINIMUM FPS:
(default: MAX)
The value (in frames-per-second) above which the mod will not operate and therefore apply any change to the default settings.

- LOWEST VIEW DISTANCE:
(default: 800)
The minimum view distance value (in meters) that the mod can apply during gameplay.

- URBAN RADIUS:
(default: 750)
The distance from the nearest urban center (in meters) at which the mod will start gradually reducing the view distance.
You can turn on the "2X" to make the reduction in view distance work twice as much at the same urban radius. This allows players to aggressively lower the view distance on close proximity to an urban area without it being affected in the immediate surroundings.

- SMOOTH FACTOR:
(default: 1/30)
The stepping (expressed as a fraction of a second) in which the mod will apply smooth transitions within a second. This is used to gradually modify the view distance when current value and target value are too far apart.

- MAXIMUM ELEVATION:
(default: 5)
The height above ground (in meters) at which the mod will restore the default view distance (set in the VIDEO options of the game).

- WHILE USING OPTICS:
(default: ENABLE)
When DISABLED, restores full default system view distance when using optics or aiming down-sights.

- REFRESH INTERVAL:
(default: 10)
The interval (in seconds) for the mod to perform its checks. Note: this also affects the distance in meters from the last checked position, meaning that a player that is not moving will also pause the mod checks as long as any parameter is not changed.

- AUTO TERRAIN GRID:
(default: OFF)
Reduces the Terrain Grid parameter to allow more performance in spite of a loss of detail. CL means 'close' and will take place when at half the distance of the Urban Radius from a urban center. FA means 'far' and will take place as soon as the urban radius value is matched. -1, -2 and -3 are performance levels, with 1 being "mid quality", 2 being "low quality" and 3 being "very-low quality". OFF restores the Terrain Grid value to its in-game defaults. Note: it might take some time for the terrain grid to change as its all influenced by the refresh interval value.


# INSTALLATION
> From Steam Workshop
Subscribing to the mod will let Steam do everything automatically for you via the Steam Workshop updater and installer.

> Manually
Unpack the folder '@VTO_uvd' from the downloaded archive into your Arma 3 installation. Add the mod to your mod parameters sequence using your favorite launcher or by adding '-mod=@VTO_uvd'. 'bikey' files are provided, you can copy the file from the @VTO_uvd\Keys folder to the Keys folder in your Arma 3 root. Server owners and admins can use the provided bikey to ensure authenticity checks in your server(s) if necessary.


# REQUIREMENTS
This mod does not require any other mods to operate.


# KNOWN BUGS
- Dialog window is not entirely compatible with odd resolutions, ultra-wide or TFT.


# CHANGELOG
v 1.0.6
Improved: Reduced mod resources usage (to zero) when far from any urban center in radius
Fixed: More than option was green when using the "DEFAULT" button
Improved: Debug behavior

v 1.0.5
Improved: Greatly optimized detection engine and reduced code
Improved: Better performance for "While Using Optics: DISABLED" mode
Added: 2X button to apply twice the reduction in view distance at the same Urban Radius Distance
Changed: Starting Preset now has "750m" as Urban Radius Distance
Improved: Debug screen now detects multiplayer games (and quits to disallow cheating)
Added: Debug screen is now a separate function and is more optimized
Plus various other optimizations that every developer has to vaguely state at the end of any changelog to look professional and cool.

v1.0.3
Added: Green indicators for active parameters
Improved: Compatibility with diverse display resolutions
Improved: Default Key is now "User20" and therefore customizable by user

v 1.0.0 - Initial release
