CPU : Q6600 @ 3.2 (400 x 8) with Zalman 9700 RAM : 6Gb (800 4-4-4-12) VGA : 6950 1Gb (Dirt3 stock) with 11.10 + Cap 4 MB : P35ds3r Rev 2.0 (last bios) PSU : OCZ 500 (12v 2x18A) HD : Raid 0 (2x WD 160 Gb 7200 rpm) + WD 500 Gb for Data CM 690 with 7 Fan... Is possible that i have problem of CPU Bottleneck when i play BF3? Thank you...
I'd say so. My Q9550 can only handle medium with consistent frame rate. Any higher would result in dipping below 40 frames which is annoying at most due to stuttering, still somewhat playable but not many never would as I said very annoying. I am going to be upgrading soon so that will help me. Ive been told if your using ddr2 like me, switching to ddr3 1333 or 1600 can help if your mobo supports it mine does not. A ssd can help with performance to. I would say a 2500k will fix ur bottleneck and you'll have to get a new board(z68) maybe even new ram. I would get a higher watt psu, 500 to me is a lil low especially if your overclocking.
What's your GPU usage in game? A dual core can play this game fine with one card so I don't think so. But why do you think it's a bottleneck? As for texasrattler I think your card is the culprit. For maxing out BF3 you need at least one strong card (6970, GTX570)
Open Task Manager, play the game and then Alt Tab out and see where your core performances are. Found this http://www.techspot.com/review/458-battlefield-3-performance/page7.html
you have the 1gb version of the 6950? your cpu slightly in single more so in multi. and the 1gb frame buffer too. what was the price difference between the 1gb vs 2gb like 20 bucks?
My CPU stay at 85% @2.4 (266*9) My CPU stay at 85% @3.0 (333*9) My CPU stay at 85% @3.2 (400*8) My CPU give BSOD/Crash @3.6 (400*9) afer 15 Sec.
I have a Q6700 oc to 3.0 ghz with MSI 460GTX 1GB Hawk. It's definitely the CPU. Open console in Battlefield 3. type render.perfoverlayvisible 1 you can see your CPU and GPU performance. You will see that you get spikes on your CPU. It really depends on which resolution you running at. I'll recommend you getting another 6950 for Crossfire. And a p1155 board and cpu when they go on sale (Black Friday)
Those benchmark results are rather misleading. The Phenom's aren't being taxed by the game, they're being taxed by the 6990, which is a dual GPU graphics card. They simply don't have the power to feed 2 GPU's as well as the i7's can. This is what the results should look like.... Admittedly this test used the BETA version, but I can't imagine the results will be that much different in the release..... I get 75% CPU load on my own X4, at both 3000Mhz and 3700Mhz.
I was talking about the performance graph (render.perfoverlayvisible 1), there was a presentation by Johan Andersson, more info about that: LINK. :boozer:
I'm running a Q6700 @ 3.2Ghz with a GTX 570 and my cpu is 100% at all times playing Battlefield 3. I started playing at the default 2.66 GHZ and as I overclocked to 3.2 Ghz performance definitely improved. This is a cpu limited game, unless your video card is the suck. Crap Daddy, the numbers Trusconi gave indicate that his system was indeed taking advantage of the overclock. If the GPU or something other than the cpu was the bottleneck I would have expected his reported numbers to be more like 85% -> 81% -> 78%. You would have seen less overall available cpu resources utilized at each overclock step, his numbers remained the same, indicating that the extra power from the overclock was being utilized. 85% of 2.4 Ghz is much less than 85% of 3.2 Ghz, so its clearly not a GPU bottleneck, his overclocking is being put to use. Though only using 85% of the cpu is pretty goofy. I haven't the foggiest why that would occur.
For the most part, BF3 is GPU based on single player while as you move to multiplayer, then you'll see it needing more CPU power. My other rig (or brother's rig) has an Athlon II X2 clocked at 3.2 Ghz and a GTX 460 card and it plays BF3 single player on medium+high settings, 2x AA, not HBAO at 50+ FPS average. I'd say pretty good for his system. GPU usage is always 90+ %
I can run BF3 with Ultra settings and 16X AF, 2X AA with a resolution of 1920 x 1080. I can just about managed this, with above average FPS. But it really does stress my setup to the limit.
My wife's PC has Q6600 @3.2Ghz with GTX 570 (stock speed). No problem playing BF3 at High settings, MSAA off, motion blur off, 16X AF. Online play: FPS never goes below 40, as high as in 80s. Q6600 @3.2Ghz with 6950 should be fine. Turn off MSAA. You should be able to run it on High settings.
