CPU OC causing rubberbanding in games?

[tulx]

Greetings!

Since many of you OC their CPUs, I wanted to ask if you have encountered the following phenomenon.
Each time I overclock my 960T when playing BF3, I get this issue (not my video). I'm well aware that correlation doesn't imply causation, but i'm able to reproduce the issue with considerable consistency. Even without restarting the game and changing the server - OC=rubberbanding, stock clocks=fine, all the time.
Is this a known issue? Am I missing a connection with some other facors?

Thank you in advance for your input!

99% sure it's to do with your network. Either the network inside your house (wireless maybe ?). Your connection to your ISP (slow DSL, cable with a lot of packetloss, don't know). Or even further upstream.

If indeed it is because of overclocking, what impact does overclocking have on your network card ? Do you change the frequency on your FSB (or whatever it's called these days) ? Maybe the overclocking has a negative impact on your ethernet or wifi interface ? Maybe it's causing your ethernet interface to reset every few seconds ?

Being a sensible person, my first idea was also, of course, network issues. But I can't explain to myself the fact that network issues could be caused by an OC of the CPU (multiplier, FSB and voltage). I use a USB WLAN adaptor. I can't see any latency spikes during the "rubberbanding".

BF3 is also the only game I've observed this in. Though games react to latency very differently.

Hmm interesting, I wonder if there is a way for an overclock to affect your USB, because you are getting the network over USB.

Do you have more details on your overclocking strategy? Are you adjusting a setting for the overclock that would affect your USB bus?

Also, you are using wireless, could there be any way that your motherboard power delivery to support higher current/voltage for the CPU results in emission of more interference (e.g., something like coil whine but instead of audio noise it makes radio frequency noise)?

If you can do a test, perhaps try using a wired LAN connection, see if the problem goes away with the overclock. Then, try a wireless LAN connection that uses the PCI bus instead of the USB bus, if you have a PCI WLAN card laying around.

Or, maybe try overclocking by increasing the multiplier instead of the FSB, or vice versa.

That doesn't mean a thing.
Most latency numbers, bandwidth numbers and other usage numbers are computed by taking averages over a particular length of time. The result is that you won't see very short-duration events.

Your rubberbanding might be caused by packet-drops over a very short timeframe (1-2 seconds or less). Might even be a delay on your USB bus for a split second. If this doesn't affect the average enough, your numbers won't show that something wrong happened.

Example: a game uses 60% of your CPU. That in itself is nonsense. A CPU is used (100%) or not used (0%). The fact that this happens in very short bursts is hidden by the fact that the numbers are averaged out over time. Similarly, you might not see very short changes in your ping, if the ping is computed over a 10 or 30 second average.

If it only happens during multiplayer then it is without a doubt your connection or some server related issue. If it also happens in single player then it has something to do with your computer.

I get your point. My PSU has this issue. Maybe something similar on the WLAN frequency. I have another PC with a PCI WLAN card. I might try running BF3 there.
Also, will try a pure multiplier/pure FSB OC.

If it only happens during multiplayer then it is without a doubt your connection or some server related issue. If it also happens in single player then it has something to do with your computer.

Heh, why didn't I think of this? Time to try BF3 SP for the first time.

So people are calling lag rubber banding now?

back around the time people started calling it lag when your fps stuttered. lag=network issue
lag /= frame-rate issue

also, rubber banding is lag due to what rubber banding is (a mismatch between your character's location on your computer and where the server thinks your character is).

I use a USB WLAN adaptor.

D: Good God

If you can, use a wired connection first off. Then go from there.
