Ok, this was a post copied from VD clan website (www.clan-vd.co.uk) which was posted by VD Frag_Master (Mike) - The indexing service option helped me the most, and now I dont even noticed the ‘chugging’. Believe some of the issues have been removed in the latest ET Pro 3.1.0 as well. (would need to check bani’s forum pages to find out for sure thou)
Question: My computer locks up or “chugs” sometimes while I’m playing with PunkBuster Enabled, what can cause this?
Answer: PunkBuster “pushes” hardware and the Windows Operating System more than most software and uses functions in the Windows API (low level functions) that aren’t used by most other programs. As such, there are a few cases where using PB can actually expose flaky hardware or other situations that don’t cause problems for other software. Here are a few things that have helped other users make these problems get better or go away completely:
If you are running Windows NT4/2000/XP, try lowering the priority of the game process. You can do this either by opening the Task-Manager while the game is running, or launch the game by using the command “start /belownormal c:\games\et\et.exe” from a command prompt or in the target field of your desktop shortcut used to launch the game. Lowering the game process priority does not reduce game performance (or just very little depending on the number of programs you are running next to the game).
Make sure you are using the latest version of PunkBuster (the latest version is always on our Download page) - also this link may help manually update your PB to the latest version when necessary.
From the game’s main screen, press the tilde key (the ~ key) to bring down the console and enter the following line (without the quotes): “/pb_system 1”.
Never close other programs from your Windows Task Manager before playing the game, either leave them running or close them through the proper interface - killing a process doesn’t always work completely even if it stops showing in the Task Manager and renegade threads seem to conflict with PB more than other programs that may be running in memory. There is a free utility that some players use called EndItAll to close all extra programs before they play to avoid software conflicts, crashes and lockups. You can get it from here.
Check the add/remove programs list in your Control Panel and uninstall any programs that you don’t use or that you don’t know what they are.
One program that seems to conflict with PB more than others is Norton Anti-Virus. If you have it installed, try uninstalling it to see if the lockups go away. Some players have reported that when this is the culprit, they can reinstall Norton Anti-Virus and the lockups don’t come back.
Other background programs that seem to conflict with PB for some users are Sound Blaster Live software and helper programs that come with video cards (especially ATI keyboard shortcut programs).
Some players discovered that they had a computer virus and that the lockups vanished after it was fully removed.
Experiment with the pb_sleep setting … try setting it to 20, 250, or 500 to see if that affects your game performance. A few players have reported that all the problems go away when they “tweak” this setting.
In extreme cases, a few users have reported that replacing their RAM (memory) or video/sound cards fixed the problem.
Also, you’ll want to turn the ‘Indexing Service’ off as this is know to have issues with PB. To turn it off go to the following:
Control Panel -->Administrative Tools–>Services–>Indexing Services–>Right Click–>Properties–>Stop–>Disable
Try the above and see if they fix any of your lag problems.
