BF3 Beta FPS thread

Caspian Border is avaialble again..... and I've started to get that stuttering/freezing again :( Took a screenshot of MSI Afterburner as you can see the memory clocks dipped when the stuttering happened so I'm starting to think that 1GB VRAM issue is true.




The rest of the clocks stayed the same.

On my [email protected] and EVGA GTX570 superclocked it works great in ultra, 4x, 1920 x 1200. In 2560 x 1440, it ditches to ~20 fps sometimes.

At 1920 x 1200 it only drops to ~30. I do very randomly get huge drops to 5 fps but im putting this down to being beta. Most of the time it run at around 45fps
 
I've dropped everything to high, not ultra and added 2x AA on caspian and it rruns better than all ultra and no AA.

Only thing is I keep getting kicked back to the browser.

Look at that again bud. They are the core and memory clocks for gpu2, not the memory clocks for both cards. Looks to me that what you have circled is at the end of a round where the gpus aren't in full use.

The stuttering you are experiencing may be server side, but detach the hardware monitor page from afterburner and expand it. Then play a whole round and have a look at the fps and gpu usage graphs. Also it's worth having the gpu usage and fps in the on screen display so you can glance at it in game when stuff feels wrong.
 
Ive just bought two of the GTX 460'S 768MB going to run them in SLI. With all this talk about VRam I hope I can run BF3 ok.:confused:

Wasnt even considering upgrading till after Xmas but when I tried to run the beta with my two 9600's it just laughed at me.:p

I've done as you asked and uploaded two screenshots of the detached graphs below. There's a red arrow where the framerate dropped to 2fps in game but the graph only shows it went to 30fps?





I couldn't see an option for GPU2 memory usage but as you can see the memory usage stays pretty constant all the way through, even when the stuttering starts so it can't be a VRAM issue causing the stuttering. However GPU2 Usage drops when the stuttering starts so maybe that's the problem, maybe the Beta isn't using crossfire properly? I've read others who have disabled crossfire and don't get the stuttering so maybe were onto something here.... I'm gonna do some more testing by lowering the graphics details and see if the stuttering appears. Will report back soon :)

Hardrive thrashing as it swapping memory, hence the framerate drops.

same as me, my hardrive was thrashing when i had framerate dips.

VRAM cache thrashing from HDD? New one on me, if anything it will be swapped from system RAM over pcie

Like I said before to someone else, play with CF disabled for a while at the same settings. You'll have lower frame rates for sure but I bet you don't see 2FPS

Of course, I stand to be corrected ;)

Do you mean you saw it dip to 2fps in the on screen display? That would suggest that the polling interval of the graph is longer than the on screen counter, so the graph can miss a movement in the fps that happens quicker than it's polling time.

I'd have to say that's my gut instinct as well. The xfire profile isn't quite right, or it's been done for a newer build and will work better in the retail game.
 
Getting about 38-60 fps, average around 45 on my 2500k 4.6GHz and 6950 2Gb on Caspian, 1920x1080 on Ultra (apart from AA which is off)

Disabled crossfire and kept my graphics settings the same. Obviously the framrate dropper to averageing 40fps but no stutter, there was one instance but lasted barely a second think that's down to it being a Beta.

MSI showed no more than 990MB of VRAM used, so that leaves 36MB as its a 1024MB card. According to my tests I'm sure this is a crossfire issue.... some new drivers have been released today so I'm going to install them over 11.10 and report back on how crossfire fares :)

11.10 Preview V2: http://support.amd.com/us/kbarticles/Pages/GPU122AMDCat1110PreDriverV2.aspx

'Improves performance in Battlefield 3 Open Beta release for both non-Anti-Aliasing and application enabled Anti-Aliasing cases on AMD CrossFire™ configurations using the AMD Radeon HD 6000 and AMD Radeon HD 5000 series of products. '

I think I am going to install 11.10 v2 aswell to see if it helps further with bf3 gameplay :)

Been saying it a while but everyone is determined this is a VRAM issue despite the obvious evidence to the contrary :p

Hate to say I told you so, but I have been for a while :p

Nice, downloading, but to drunk for gaming now!

After installing the 11.10 Preview Driver V2 I still got some stuttering, in two places which I've shown here:



VRAM stays the same all the way through, but the GPU Usage for both cards drops causing the FPS to drop. Crossfire has not been fixed with these new driver :( On the bright side at least we know its not a VRAM issue and so don't need to buy new cards.
