Low fps battlefield 3 560gtx ti sli

[mephistois]

Hi, I'm seeing people talk about and show charts on how 2 560gtx ti graphics cards run battlefield 3 40-80 fps on ultra. Mine runs at 60(never any higher even on high graphics) and drops down to 30 frequently during gameplay while on ultra. If left on high the fps stays at 60 pretty constantly. This seems low compared to what many others are experiencing. What can I do to try to improve the hardware I am using?

How much VRAM do the cards have?

It probably stays at 60 because you have Vertical Sync on. This is good; it's the maximum amount of frames per second that your monitor can display. More than that is pointless. 30 is sad, but it's probably because others don't have AA on (if you don't, you should, but I'm guessing you do).

Duh, forgot about V-Sync. Can't that also play a role in the framerate drop? I remember seeing something that with V-sync will drop the framerate to 30 if the hardware can't make it to 60. Regardless, turn V-Sync off (again, assuming you have it on) and see what that does.

Ok I'll try this and get back with you guys shortly

Well, turning V-Sync off my fps dropped to 15-25. This is only in multiplayer perhaps because of the distance rendering. I ran a few mins in single player to compare and got 60-90fps.

1gb each

check if both of the cards are worrking when ur playing the game ,
run a program like MSI Afterburner , to check the GPU usage of each of the cards while the game running , 2 ti should be able to run the game just fine , but do not expect TOO much , 3 * HD6970 CrX reaches ~130 FPS so 70~80 seems pretty good with the ti s
and enabling V-SynC should make ur frame DROP and not improve it , and also be sure to play the game @ Fullscreen , and that the resolution of your desktop , matches the one of the game ( Desktop @ 1080 , Game @ 1080 )
and u didnt mention ur PSU

 

[zakattak80]

why hasn't any one asked what his resolution is?

 

[mephistois]

Both cards are working. About a 70fps difference between High and Ultra. Resolutions with game and desktop are both 1080. 1200w psu

I would be willing to post a video of game play. Everyone keeps saying these cards run BF3 on ultra but, I'm just not seeing it. At least not at a good fps.

Most likely the people that are saying they have "80fps on ultra" Mean everything on ultra except deferred AA.

If a 6990 is rocking out 82.9 FPS @ 1080p on ultra, I would not expect the same from 2 GTX 560 ti.

You should be getting approx 64FPS on average, but again that's not consisten on multiplayer vs single player.

Also, they may have it OC'd. But yea. You can expect 2 GTX 560 ti to perform at about 75-80% of the 6990, not including optimized drivers.

Mine are OC'd. I took off the deferred AA and average around 70fps now. That one setting made a huge difference so thank you very much for mentioning it.
