BF3 on MBP 2011 15"

[JazzyFizzle]

With 256mb vram, it would be very hard for it to keep up.

Check out notebook check here where there is a comparison of the 6490 with some games.

It appears it would run, but the 6490m they have has 512mb vram. Explains why the charts look pretty good against the 6750m 1gb.

Thanks, yeah I've been on there looking. From what I gather, the VRAM shouldn't make a huge difference.

I play bf3 on my desktop (3.4GHz quad, 4GB RAM, HD 4870 1GB). It can run at about 30fps on ultra 1680x1050, but I prefer to play on medium because I can really tell the difference in response time between 30fps and 60+. It makes a huge difference when playing online. And I cant even tell the difference in graphics.

Hopefully with everything low, I can get the same performance on the 6490m? HnZ roughly how laggy is it?

hey is anyone playing this game natively at 1440x900??
im regretting getting the hi-res option cause now i have to resort to playing it blurry at 1280x800 (i cant play natively at 1680x1050...)
weird thing is, i can't downres to 1440x900! the option isnt there...
it goes straight from 1680x1050 to 1280x1024....no 1440x900??

anyone found a workaround? im getting really decent performance at 1280x800 (35-60fps...hovering on 40fps)...so want to bump up the res a bit...

thanks all

2.3 GHz i7-2820QM
6750M @ 790/970 MHz
No ThrottleStop (CPU temps are not supposed to go that high - it started to have a physical impact in the processing power of the chipset)
8 GB RAM
11.10 Final (need to reinstall from 11.10 beta 3)
45?-60 FPS

All medium, no MSAA, no AA PP, 2X anistropic filtering.

vRAM makes a large difference in the textures you can load. High takes up about 768MB, and ultra takes up 1024MB. If you have a lot of video ram, you don't have to load new textures into vRAM as often.

Apparently, the 6750M has a factory memory clock of 900 MHz, whereas the 6770M has a factory memory clock of 1600 MHz, which translates to about 80% faster memory throughput, or 15% faster pixel pushing. (laptop review)

what res are you playing at? and what's your macbook's display?
I'm on a hi res 2.4ghz...4gb ram, 6770m 1gb
textures high, everything on medium except shadow (low)..post AA on high, deferred AA off. AF on 8x, motion blur off, resolution on 1440x900 (played around with registry - not native i know, I'm regretting getting this high res screen now)...getting 35-60. hovering on around 40
750/900 @0.96v

considering pumping the clock up a bit more, but worried of long term damage (will purchase apple care later, but you know...)

1440x900. Keep in mind that Windows installs are notoriously fickle with the way games run. My friend's Bad Company 2 install keeps crashing, I have framerate issues in Modern Warfare 3... Etc.

I don't know if the 6770M really has a 1600 MHz memory clock. That's what I believe Notebook Review (or was it Notebook Check?) said about the 6770M. Regardless, people seem to be squeezing around 2-5 FPS more out of that card.

That was just a error they never corrected. It happens.
Check out wikipedia they say it has the same 900 Mhz. If it was 1600Mhz something would be wrong. While it is theoretically possible the fastest GDDR5 currently used is highend Desktop cards is 1375Mhz and it would be very unlikely they would run something higher on a mobile card considering the IMC and memory would also suck a lot more power at this setting.
Wikipedia is also better revised and thus more trustworthy in this respect.
They both run 900Mhz someone with a 6770M can confirm this I am sure.

Got it to work. This website i think mods the ATI drivers to allows it to work on 'restricted' laptops...

anyways..
just a gauge... those with late 2011 MBPs, what are your settings and what fps are you getting??
im a 2.4ghz quad...4gb ram

OCed to 750/900 at 0.955v

High textures, low shadows, medium everything else. SSAO on, AA off, post AA off, 8x AF.
1280x800 i get 35-60, hovering on 40 most of the time.

I did buy the hi-res option and am starting to regret it. If i had stuck with the original 1440x900 screen perhaps i would've been able to run this game natively (sharper image)....darn it

Hows does this combo run?

Medium textures, No shadows, medium everything else. SSAO off, AA off, post AA off, 1x AF @ native res.

Also, can you not push your GPU to 800/900 like the 6750's?

Thanks!

you cant turn shadows off. hence i kept it at low.
I would say that combo would get you around 40-60 fps.
textures dont really hit your fps rate - that depends on the amount of VRAM and the 1gb on the 6770m is plenty.
AF isnt a hard hitter either. i switched from 4x to 8x and even 16x and didnt notice any dropped frames.
AA is defnitely a big slugger. I turned it off completely and instead opted to have high post AA (FXAA). this thing is magic. I turned it all the way up and it has almost 0 impact on fps and significantly less jaggies.

I can probably OC it to 800. but I figured the since the 6770m was designed to run at 725, OCing it to 750 is only a 25mhz overclock - very minor overclock. i don't really want to push it seeing as im happy with the performance already .

It just does not work

Just wanted to inform you that Battlefield 3 is working on ULTRA settings with 30 FPS + on the early 2011 MBP 15" 2,2GHz Model.

What did I do?

- buy 8GB of RAM
- install them
- Install Windows 7 64-Bit on Bootcamp
- De-Install Bootcamp ATI drivers
- Install 11.10 Preview 3 Drivers!
- use ATI Tray Tool to overclock to 750/900 with 0.955V

Then just install the game and enjoy!!! It's ****ING AWESOME!

Settings:
All on ULTRA and 16x AA
Resolution 1680*1050

Hello everyone,

I have an early 2011 MacBook Pro with the highest specifications and ALL this just simply does not work for me.

I uninstalled special AMD Bootcamp driver for the graphics card, installed the newest 11.12 driver as well as the ATI Tray Tools with the ThrottleStop. I configured them as it was recommended in other topics/forums.

It only adds me maybe (maximum) +5 extra FPS so I have around 19-30 FPS (constantly changing, which is annoying when it drops to 17-19) on my default (high) settings.
It is not ~40 FPS on Ultra, as it was promised, at all.

Maybe I am doing something wrong.
Thanks for your recommendations/corrections in advance.

Has anyone else tried this to work?

I think Meetster was a little bit excited and exaggerated slightly.

I got about 35fps or so on medium settings with a similar overclock at 1440x900. 1680x1050 is quite a few extra pixels to shunt around so I would expect poorer performance, and certainly at ultra settings. Drop the detail and AA and it should be perfectly playable though.

I was thinking of playing it at 1400x900 with medium settings.
