Bad Company 2 dx10 question

[tomster2300]

So this is a tip as much as a question...because I'm not sure if this was really the fix or not.

I get between 50-80 fps in Bad Company 2 with everything turned to medium / high (it dips with explosions that happen right in front of me, etc.)

I went into the settings.ini and changed everything to high, lowered the AA from 2x to 1x, and then changed dx from auto to 10 (I wasn't sure if the game was defaulting to dx9 or 10).

Anyway, I now get the same fps like before, but now the overall experience is silky smooth. The menus slide in and out now with absolutely no lag, the fade to black at the end of rounds has no clipping. Explosions are crisper...it's just like some kind of hiccup on my computer's end is now gone. It feels like your computer does following a defrag.

How can this be? I haven't updated my ATI drivers and nothing has been changed on my computer. Steam did update itself, and I know Bad Company 2 was just patched, but nothing ran like this until editing the ini yesterday.

Can forcing dx10 make the game run better? Even though I'm running Win 7 and have a hd4870, could it have defaulted to dx9 and caused conflicts?

I would assume changing the AA from 2 --> 1 is the reason why it's running better frame rates. Also the game defaults to DX10 if your hardware + OS can support it.

That's what I thought, but it just seemed like too much of a difference from only changing AA. 2x - 1x isn't that much, is it?

1x is the lowest you can go in BC2 - there is not a none option.

Changing AA from 2 --> 1 helps stabalize the frame rate when an explosion goes off near me. I don't see a reason why forcing DX10 would change anything when you already are running DX10.

1xAA=0xAA I believe, other games just don't list it as 1xAA to confuse people. 1xAA isn't different because it's not chaning any Antialiasing happening on screen.

You could try to set the DX to auto again while not changing any other settings and see if that changes frame rate. If not, then that means there is no difference between forcing it and leaving it alone.

I see, and that makes sense. Either way, the changes are refreshing.

Anti-aliasing eats up a lot of video processing power...almost as much as increasing the resolution.
