VVIS++ is a community-made modification of Source's VVIS developed by ficool2. It significantly reduce VVIS compile times, while providing same result as regular VVIS.

Differences

• Depending how big the map is, or how the map was optimized, VVIS++ will be 50% to 2700% faster compared to original VVIS.
• Scales up to 64 threads
• Added AppID mounting if steam_appid.txt is present beside the exe

Supported games

VVIS++ is currently available for all games on Team Fortress 2 branch and Garry's Mod.

Other games/mods tested

VVIS++ also unofficially works with the following games, other VBSPs or engine branch:

Game	Engine branch (game)	VVIS++ Version	Notes
All Source 2013 Singleplayer games Half-Life 2 (including Episodes) Half-Life: Source Portal	Source 2013 Singleplayer	Team Fortress 2 branch	Install to any Team Fortress 2 branch game or Source SDK Base 2013 - Multiplayer's bin/x64 folder normally, then open Hammer (or Hammer++) in your Source 2013 SP game, change VIS executable and point it to $SteamUserDir\Your TF2 branch game\bin\x64\vvisplusplus.exe. Source 2013 SP's .bsp and all of its compilers (VBSP, VRAD) are compatible with VVIS++. Tested with Half-Life 2 (with VVIS++ installed on Half-Life 2: Deathmatch directory).
All Source 2013 Multiplayer games	Source 2013 Multiplayer	Team Fortress 2 branch	Install to any Team Fortress 2 branch game or Source SDK Base 2013 - Multiplayer's bin/x64 folder normally, then open Hammer (or Hammer++) in your Source 2013 MP game, change VIS executable and point it to $SteamUserDir\Your TF2 branch game\bin\x64\vvisplusplus.exe. Source 2013 MP's .bsp and all of its compilers (VBSP, VRAD) are compatible with VVIS++. This method will also works with pre-2021 version of Counter-Strike: Source, Half-Life 2: Deathmatch, etc... games, aswell as pre-2021 version of Source 2013 Multiplayer (you will need to have both version of the game(s) in Team Fortress 2 branch and Source 2013 Multiplayer installed, with the latter on a separate folder named "Counter-Strike: Source pre-2025" for example, then open Hammer on your Source 2013 MP game, change VIS location to vvisplusplus.exe located on your TF2 branch game).
All Source 2004 and Source 2006 games	Source 2004 Source 2006	Team Fortress 2 branch	Not supported. VVIS++ can read Source 2004 and 2006's .bsp (meaning it is compatible with Source 2004/2006's VBSP), however, Source 2004 & 2006's VRAD will fail to compile maps compiled with VVIS++.
Mapbase games or Mapbase's VBSP	Source 2013 Singleplayer with Mapbase	Team Fortress 2 branch	Mapbase's VBSP are compatible with VVIS++. For installation, follow the same instructions as Source 2013 SP games.
