BFBC2: 20fps drop after moving to Windows 7

No, read the thread and links provided....

Note FPS drops going from quad to dual

I'm speaking as a person with a C2D and Xfire 4870's that plays this game every single day. he should be running absolutely fine.

you guys are leading him nowhere.

It's obviously a crossfire or driver issue. He should have no problems playing 40-60FPS @ 1920x1200 with 4XAA/16AF, settings cranked, in DX10 with windows 7 64bit. I know this for fact, because this is how the game runs for me. Even if my C2d is running at 2.8ghz, the game still runs fine. Don't act like you can tell me I'm wrong using some Phenom II benchmarks when I have roughly the same system as the OP.

You are wrong. Period. So instead of telling him useless information, help him figure out what is wrong with his Crossfire setup, because his problem is Crossfire or driver related.

Here are the results of 23 minutes of benchmarking that I did with FRAPS from the other day. I even had VSYNC on the entire time

settings were
1920x1200
4xAA
16AF
All settings on highest

This is in Win7 Home Premium 64 bit, DirectX 10

Frames, Time (ms), Min, Max, Avg
70625, 1402422,,,, 25,,,, 62,,,, 50.359

Considering his GPU's are faster than mine, it should be obvious that he is having crossfire issues.

Key. to see if the ATI drivers are enabling Crossfire, right click on the ATI tray icon, mouse over the first GPU, go to CrossfireX settings and enable the "Show Crossfire Status Icon" option.

Load up BC2 and you should see a fairly large ATI icon in the top-right corner as soon the intro screen appears. Come back and tell us if you see the icon or not.

I'm afraid you are wrong. There are tons of threads, all over the net, about quad cores making a big difference over dual cores for BC2. Even people with 4Ghz dual cores complaining that the newer stock speed quad cores perform better. The advice to upgrade to a quad core has also resulted in many people doing so and then reporting a significant performance increase in BC2. This is usually under Dx11 though. Dual core users are often recommended to stick to Dx9.

I also play this game every day. I'm just shy of 500 hours, not even counting time in the beta and on non ranked servers for weekly clan matches and practises.

Personally, overclocking my quad core Q9400 from 2.66 to 3.9 improved my mininium frame rate from 30 to 50, with a nice improvement on the average frame rate as well, on a single 5850 clocked to perform just above a stock 5870, on Win7 64 so Dx11. BC2 is a highly multithreaded cpu hog, but I still love the game

That being said, the op still may have a problem with his crossfire setup. He mentions he has a nvidia board. Are we sure his crossfire is actually working on the nvidia board? Perhaps the op can download gpu-z and confirm whether both his gpus are really under load or not.

We are talking about this guy's particular problem, and in this regard, him having a c2d has shit to do with shit. sure, C2d's are slower than quadcores, but again, this has NOTHING to do with this guys problem. My machines performance is plenty proof of this.

Crossfire runs fine on Nvidia chipsets. My laptop has an Nvidia chipset. his crossfire setup was working fine until he went to windows 7. It's driver/crossfire related. Stop trying to tell this guy his CPU is the issue.

hawtdawg, read my post again. My first three comments were clearly directed at you. My last comment was directed towards the op's problem.
