Half-Life CGShaderThis is a pixel shader for bloom-like effects on any Half-Life engine game.
Some examples below, click any thumbnail to view the entire image.
To install, extract the files into the mod's upper directory.
For example, SteamApps/username/team fortress classic or SteamApps/username/counter-strike.
To remove, delete all the files extracted from the zip. To temporarily disable, rename the opengl32.dll file to something else such as opengl32.dll.disabled.
This plugin needs quite a powerful PC and a reasonably up to date graphics card with pixel shader support. For reference, my Athlon XP 2500+ with 9600XT runs at 100fps with this at 800x600. You can increase or decrease the bloom amount with F1, higher values will be slower. Decreasing your resolution is a good way to keep a high fps.
Apparently this is now picked up by VAC (Valve's Anti Cheat system) as a cheat and you will be banned for using it on a secured server. Please restrict your use to demos and unsecured (eg. LAN) servers.
