This update is recommended for Windows users with Intel Hyper-Threading Technology (HT Technology) enabled processors, multiple processors, or systems with a dual core processor. The update is also required for Windows and Linux server admins as it addresses a recently identified problem with servers left unoccupied for very long periods of time (these servers will appear to be operating normally, but will crash clients that attempt to connect to them). This update will bring any previous version of the game (1.0.0 or 1.0.4) up to date and will not affect pure server, PunkBuster compatibility or protocol consistency.
id Software and Raven have worked with Intel to dramatically improve QUAKE 4 performance on systems with HT Technology, multiple processors, or dual core processors. Players who have a system with one of these configurations will notice performance gains in QUAKE 4 of anywhere from 25% - 87% depending on processor type. If you do not know whether or not you have a multi-processor, dual core, or HT Technology enabled system, please see the ReadMe file for simple instructions on checking your system. Please use the form at http://www.idsoftware.com/bugs/ to report any issues you find with the 1.0.5 update.
Here are some test instructions for those of you who like to benchmark:
1. Install Quake4 with default installation settings.
2. Download and install the Quake4 patch to enable SMP support for multi-core systems.
3. Place your mytimedemo.demo file in the Quake4\q4base\demos directory within Program Files.
4. Launch Quake4 by double-clicking the Quake4 icon on your desktop.
5. After Quake4 has loaded, type ‘~’ to bring up the command console.
6. In the command console, type ‘r_useSMP 1’ to enable SMP support. Alternatively, type ‘r_useSMP 0’ if you want to turn off SMP support.
7. Type ‘timedemo mytimedemo’ to start your timedemo.
8. When the time demo has finished running, you will see a dialog box with FPS performance.
