High Frame Latency spikes in all games.

Ever since I attempted to SLI my gtx 680s with a Corsair 850w power supply, my frame latency spikes have been occurring way more often then they use to. Almost all games now have a really annoying microstutter that just won't go away. Most games randomly spike to 120ms resulting in unplayable game play. Did the attempt to SLI actually cause damage to my hardware or could this be driver related? i have the latest beta driver from NVIDIA (331.40). What should I do at this point? RMA?

i7 3770k @3.9ghz
MSI gtx 680 2gb 1x for now and hopefully after this thread is answer it'll be 2x
Corsair H70 cooling
MSI z77a GD65 motherboard
Corsair Vengeance 8gb memory
Corsair TX850w V2 PSU
3x 200mm LED fans, 3x 120mm LED fans, and 2x regular 140mm fans
1x 500gb HDD
1x DVD RW drive

Your motherboard has 3 pci-e slots. Speeds are the following: 16/8/4. What this means is that your second card is going to run at a slower speed than the first one. Normally running multiple cards will cause micro-stutter but your motherboard is exacerbating the issue. You can try reverting to an older driver version but I doubt that would achieve anything.

What you can do is take out your old card and put the new one in your x16 slot. Run some games and test the latency. You should get results similar to your other card. If you don't, then your new card might have an issue. Otherwise, your motherboard is holding your 2nd card back.

I' not even running SLI right now. This issue is there with only one card installed. I haven't even tested if the issue is there with SLI on. And I didn't really buy a new card, I just put it in the corner while I save up money to get a new power supply. The 2nd GPU I installed was even older than the one I had already in my computer and I knew that it worked well. i decided to SLI both of them the other day even though I wasn't sure that my Corsair 850w can handle it. When I installed my 2nd gpu and booted up the pc, the computer restarted by itself before it even booted (I thought maybe it did that because I installed new hardware) then when windows booted, I ran a benchmark and I could see the benchmark itself but the screen kept flashing green colours. I decided to change the SLI bridge and after that everything worked fine. But after a few hours, I panicked and decided to remove the 2nd gtx 680 anyway and go back to a single 680 because of all the weird stuff that happened. Now that I have only one gtx680 like i use to, I get weird frame latency. Maybe it was there all along since i've been struggling with frame rate stutters for a while, but it's the first time that i actually monitor frame latency.

First off your psu should easily be able to handle sli so long as it's not super old. I will say that I have never heard of frame latency, either being used or as a metric for device performance. Usually you can measure latency on online games as it applies to your connection to the game server. Otherwise latent frames are simply discarded by the video card. FPS is what you should be using to measure performance. On that note, make sure that sli is turned off in the nvidia control panel. If that doesn't fix the issue, you might want to revert your drivers back to an earlier version. You might also consider wiping the old drivers from the system with driver cleaner first before that.

I re installed the Operating system and nothing changed at all. I seem to only get a latency problem with World of Warcraft. Every hour or so while playing WoW I find that some people are running in place and all actions are just frozen as if my internet just show off, but after about 5 seconds or so, everything comes back to normal and the screen fast forwards to where it currently is. This happened right after I installed and uninstalled that 2nd GTX 680.

That's not an issue with the video card, that's a networking issue. It may just be coincidence that is when you got your card. You will see that occur when your computer losses communication with the server. This of course can be a number of things. For example, time warner usually updates ip addresses at night, hence there is about a 5 min down time. It could also be your router/modem or your computer's Network card(nic).

I don't think you specified in your first post but you should now. Are you getting frame rate spikes or online latency? Does this issue occur only in online games? The difference between the two is that one is affected by your graphics cards and the other is not.

I haven't seen this problem happen on any other game besides WoW, and i get no unusual frame rate spikes. I do get frame rate dips, but that's only when crazy stuff happen on my screen, which is expected. When this problem happens in WoW, sometimes i see the WORLD latency spike to about 1500ms while home says low at around 40ms. That only happens sometimes while other times both world and home MS stay low. I will try to play other offline games for an extended period of time to see if this issue happens, I highly doubt it will though.

Are you connected through wireless or wired?

wired, I also ran a program called Pingplotter while running WoW and it gives a total of 30% pocket loss when my problem happened. This problem now can be anything from the windows errors in my OS, my modem, or the computer itself...pretty much anything. sigh..

my network card is called IntelĀ® 82576 Gigabit Ethernet Controller BTW

Here is something you can do:

Get your router's IP address and then open command prompt and ping it.

It should return with no lost packets. If it does return lost packets, the problems is with your network.

pinging my own ip returned no lost packets at all

I've also re installed my 2nd gpu and started using SLI again. I have also alternated between both GPUs and the problem still occurs. After that I reinstalled the OS one more time and moved to a different room completely with a different Ethernet cable...still same crap.

Any chance you have another system you can run the game from on your network? If you could, and it runs with the same issue, that means it's an issue outside of your control (could be isp or game provider). If the issue does not occur, that means there is something wrong with your computer. Most likely, lan drivers.

I know this is an old thread and I'm sorry, but it's not your network. Something is wrong with your hardware. I have the same issue, and I've been searching forever and I can't find a fix at all. I don't have frame time spikes at all until I play for a little bit, maybe 2 hours. Then, it starts spiking. Restarting windows fixes the issue, but I don't like doing that because it means I have to leave game. I average 15ms frame time, then it spikes to 30-40 every 1 second.
