Here is an interesting article I recently read on things one can do to reduce system latency. Although the article directly relates to DAWs (digital audio workstations), it also applies to any system that renders real time audio and video streams (gaming PCs, creating youTube content, livestreaming, Twitch, etc.). The intro paragraphs explain what DPCs (deferred procedure calls) are and provides some tips you can use to smooth them out and improve system performance. These tips aren't designed to boost FPS, they help users discover and correct the system lag that causes jitters and stutters in video and audio streams. Got a lag issue you can't figure out? The answer just might be in here. war

All, Within the last month or so, I've noticed quite an increase in lag/stuttering in BF3 multiplayer and decided to investigate to see what I could do on my end and pass my experiences along to others. My problem is thus: In game, with perfmeter running, I notice significant stuttering. The stuttering is worse when I'm moving in some direction then look in another direction. The number of players in the server really doesn't make much difference, and it happens in all BF3 servers I play on, but our server does seem a little worse than others for some reason. Here is a YouTube video that describes what I'm experiencing. I'm not alone in observing this phenomenon, and there are tons of threads on almost every kind of forum you can imagine that discuss folks trying to get to the bottom of this issue. I would like to know if you guys have experienced it and what you did to solve it. Here's what I've done so far... System specs in my sig. I have most eye candy turned off, FOV is 70. Avg. CPU is about 70% - 80%. Never seen my CPU go to 100% in BF3. HDD access looks normal with no signs of excessive disk access. - Clean install Win7 x64 - Latest BIOS - Stock clocks - HT disabled - C1E disabled - Virtualization disabled - Latest chipset drivers - Core Parking diabled - Latest Nvidia drivers installed - Tried two different video cards, no change in the issue - Latest NIC drivers, IPV6 diabled (unavailable in my Comcast segment anyway) - Some network stack tweaks (no effect that I could notice) - Vsync on - FPS limited to 59.95 in user.cfg (with appropriate FPS set in game, with ingame vsync on) None of these changes made any real difference... the underlying issue is still there. As far as I can tell, my PC is running well and doesn't appear to be stressed by running BF3 Multiplayer. I've played the game since the beginning without any problems, until recently. I really don't think it's my hardware or my network. I'm going to try different games so that I have something to compare with. More as this develops. war
