CPU drop resulting in game freeze

Post by lesyork »

Hi guys,

Been getting a problem recently, I believe it's only been present since I updated to 0.981.

The game runs on core 6 (0-7), always maxing out that core as it's supposed to. Occasionally I get a drop in CPU load, sometimes 10%, sometimes 50%. This happens every 30 seconds to a minute, and causes the whole game to halt, then continue. It's not a network lag issue.

It's making the game occasionally unplayable - flying helis is out of the question when you don't know if it'll freeze up in a dive or not.

It's running on a MacBook Pro 2.2Ghz i7 with an AMD 6750M. I don't ever recall this happening previously.

Graphics drivers are as up-to-date as they can be whilst still working with my machine. Just done a clean Windows reinstall to try to fix this. It's the only thing installed on here, no luck. Closing Mumble doesn't help.

If there's any tests or diags or dumps you want, please let me know and I'd be more than happy to provide.

Thanks.

You need to change your power settings in windows, if I had to guess.

under Windows XP using SpeedswitchXP this is easy.
NOt sure if it works in Vista/7/8 though.

Alternately, you might need to change something in the BIOS, but I have no idea what the MacBook Pro BIOS looks like for SpeedStep (i7 feature for power savings) settings for booting into Boot Camp windows, or if it even exists.

High performance mode is on, nothing being restricted. Can't change anything in BIOS, I don't have one. Never used to have this problem previously though.

3. Download Bitsum Process Lasso Free. Process Lasso - Automate and optimize priorities, CPU affinities, power profiles, and much more!
-- Start PR, alt tab to desktop, open ProcessLAsso window, right click on PR.exe, TR.exe, BF2.exe, PRMumble.exe and pnkbstra.exe and pnkbstrB.exe and give them default priority status of High, set the Tr PR and BF2 to gaming mode, and give them higher access to RAM, CPU and Virtual memory resources.

Just a guess, but you should also try either manually or automated shutting down of background processes.
Might also want to try running
single player local

then

turn off antivirus and single player local.

then

turn off antivirus and online multi player.
Another guess is you have a firewall or antivirus that is messing stuff up.

What OS are you using?
