Warnings

The macOS (OS X) version of this game does not work on macOS Catalina (version 10.15) or later due to the removal of support for 32-bit-only apps.

Counter-Strike: Condition Zero is a remaster of the original Counter-Strike with Bot AI, enhanced graphics, and a singleplayer challenge mode. Counter-Strike: Condition Zero Deleted Scenes is a linear single-player game based on multiplayer Counter-Strike's gameplay, with inspiration from Half-Life.

The game was originally announced in May 2001 and was in development by Rogue Entertainment. Later that year, the development company went defunct, so Valve Software handed development over to Gearbox Software, who had prior experience with the Half-Life 1 expansion packs. Gearbox overhauled the game's graphics and models, and worked on implementing several new maps and features (including some which went on to be added to future games), but delays and changes in the plan for the single-player resulted in Gearbox pulling out of the project and the single-player development being handed over to Ritual Entertainment. Ritual converted the multiplayer maps from Gearbox's Condition Zero into 18 unconnected single-player missions, and the multiplayer portion was handled by Turtle Rock Studios, the developers of the Xbox port. The game was expected to release in early 2003 alongside the Xbox port, but critical reception was poor, so Valve assigned Turtle Rock to finish development. The resulting product was similar to Gearbox's version, but contained mostly remade maps from the original game. 12 of Ritual's single-player missions were released as a bundled side-game subtitled "Deleted Scenes", with the 6 remaining missions being re-added via updates.

The multiplayer service is still online with user-run servers on Steam, and the Steam version continues to get stability updates along with the other first-party GoldSrc engine titles.

Issues fixed

Detail textures option is greyed out on hardware that supports multitexturing

This can be caused by using workarounds to enable overbright lighting, including for other GoldSrc titles.

Revert changes (Nvidia Profile Inspector)
Run Nvidia Profile Inspector. On the Half Life profile, set Extension limit to Off. Apply changes. Notes If forcing antialiasing through Nvidia Profile Inspector, it will be necessary to change Antialiasing - Mode to Enhance the application setting.

Revert changes (GLIntercept)[citation needed]
Delete or rename OpenGL32.DLL.

Black screen on startup

Disable FBO rendering
Add -nofbo in the game's launch options.

Windows 7/Vista Performance Fix

In Windows 7 or Vista with modern hardware, some users may experience extremely low frame rates during gameplay.

Set HL.exe to high priority[citation needed]
Open Half-Life. Press Ctrl+⇧ Shift+Esc in order to open the Task Manager. Under the Processes tab, find HL.exe and right click it. Set its priority to high.

Performance issues with dynamic lights on Intel graphics (OpenGL)

Dynamic light sources being present, such as the flashlight or flickering lights, causes significant frame rate drops and lag spikes on Intel graphics.

Use this GLIntercept config
Note As this method uses a custom OpenGL32.dll, it should not be used in VAC-protected servers. Doing this also fixes overbright lighting.
