GPU Usage fluctuating, FPS Dropping in BF3 nVidia 770

post #1 of 9
Thread Starter 
Just upgraded my PC with an Intel 4770k, Gigabyte Geforce GTX 770 and a Cosair HX850 80 Plus Gold. The problem I'm having in BF3 is on Ultra (and even a few times on all settings low) my FPS will suddenly drop to the single-digits and then come right back up, but it happens pretty often in-game. Looking in MSI Afterburner I see when my FPS drops, so heavily too does my GPU Usage.

I've checked and tested my CPU temps, under 100% load they don't go above ~56 C. I think the max GPU Temps I've found are ~69-70 C. I haven't tweaked/overclocked anything on my system either.

I do only have 4gb of DDR3 1333 RAM so I thought maybe that was bottlenecking me, but I don't know.

I had the same problem. Roll back driver to 313.22 and see if you still have issues. I run z87 dual deluxe, 4770k and 660oc sli, and I had to roll back to fix, at least on windows 8, windows 7 all driver versions seem fine

I'm currently running Windows 7, forgot to mention that. Is there any other reason you think the problem could happen, if the Windows 7 nVidia drivers are fine?

Hey OP I too was having the same problem with 4 gb ddr3 1333 RAM. Is it happening a few minutes after you drop into a match like it was for me? It was pissing me off for a good while until I found forums of people complaining about it. The fix according to the post I read was to pop in another 4gb of ram. I was dubious but was thinking of getting another 4gb anyway so I picked it up and boom: stutter gone. I have no idea why it worked but it did, I changed nothing else.

Well the 4gb was 2x 2gb RAM sticks, I originally got it off a friend. So I just bought two 8gb sticks of CL9 DDR3 1600 for a total of 16gbs. The issue itself seems to have completely resolved so I'm happy, lol.
