Bizarre Battlefield 3 performance gtx 560 ti 448

Hey Guys,

I recently upgraded my GPU to a GTX 560 ti 448 from Inno3D. I've had a lot of trouble making the move from and AMD card to Nvidia and upgrading my PSU, but the bottom line is that everything now seems to be working ok except for one thing: Battlefield 3.

I was playing on an HD 5750 comfortably on mid-high settings averaging a smooth 40fps, even with HBAO and AF. Since I bought the GTX 560 Ti 448, however, things have been pretty horrible. I can't seem to get any better than 50 fps, even on low settings with no AA or anything. Even then, it chugs along like a pathetic dying mule between 0-19FPS any time I move too quickly or, god forbid, pull the trigger.

I initially tried the included 285.66 drivers, then upped to the latest beta 295.51 driver once I noticed the problems in Battlefield 3 to see if it was a driver issue, but the problem persists.

I invested a fair bit of cash between the card and the PSU, but I'm getting horrible results in the game I probably play the most. So my question is, what gives??

AMD Phenom xII OC 3.4Ghz
4GB Ram (2x2GB)
GTX 560 Ti 448
Running 1920x1080.

I'd ask on Battlefield/Nvidia forums but the community here is much more civil and reliable.

Hope you can help guys.

EDIT: I just noticed that this only happens on Multiplayer. On SP I'm getting a comfortable average of 55-60 with all settings on Ultra except textures and no MSAA. I don't know if that helps the diagnosis (Note: it's definitely not a connection issue)

That's the driver I have installed, sorry for the confusion bud. I can't really because I have soooo many programs for work and things installed on here it would be a nightmare going through all that.

Could it just be that the drivers aren't quite there yet for my specific card? It's a new and limited GPU so it may be the case that NVidia are still ironing out some issues for Battlefield 3 with this particular card?

It's basically a GTX570 so I'm sure the drivers should be able to handle it fine. I'd try mega's idea.

Multiplayer uses way more CPU than the single player. There's no way DICE considered multiplayer when specifying the system requirments.
Hit ~ to bring up console
Type Render.PerfOverlayEnable 1
Type Render.PerfOverlayVisible 1
Hit ~ to close console

The graph shows the time taken in milliseconds by both the GPU and CPU to render frames. If the GPU line is lower than the CPU line, then the CPU is bottlenecking the video performance. Check it out and let us know.

*Edit* As a note I had a lot of swapping with only 4GB of RAM installed, and each time that HD light blinked, I got stutters and hiccups. Upgraded to 8GB and whadya know no more frame rate dips and I've even seen total memory usage hit 4.3 GB.

but the 5750 plays better than Nvidia some how Nvidia Drivers seem the culprit once again.

Hey thanks guys.

So I tried the console commands and it shows that the CPU is only slightly above the GPU line, though the GPU actually spikes above it during firefights etc.

Disabling the Raw Mouse Input did improve things, so thanks for that. I guess all I can really do is upgrade RAM when I get a chance and hope Nvidia get some better drivers sorted out.

Cheers again guys.

Wells it's Radeon not Ati plus many other people are playing BF3 just fine on 4gb of ram I would suggest OP to just go Radeon like most everyone is now in days and TH this month recommend 14 Radeons out of 18 cards mentioned.

Ya I know it suck to be an Nvidia fanboy today och!

LOL...

I just need to say thankyou for the helpful info, I have recently just upgraded from a 1gb GTX 460 to the new 560 ti 448.

I have had nothing but problems with BF but the main issue is that after 20 mins of gameplay the system starts going crazy for example if i am in a jet 1 second i am taking off then the system locks up and then the next second i have either crashed or i am at the other end of the map.

I originally thought this was due to not having enough Video memory so i lowered the resolution and set everything to high instead of ultra but made no difference.

However my 460 ran absolutely fine @ 1920 x 1080 4xaa all on high settings. I like the others have stated only have 4gb of ram so i think i will upgrade this to 8 or even 16gb this weekend.

I have noticed that BF3 maxes out my Ram so i did set pagefile up on the SSD hoping this would help but it has not made any difference. I will post my results.
