Many people appear to have terrible performence in the beta version of Battlefield Bad Company 2. The first reflex for most people is to actually think their computer is bad. Well the good news is that it’s likely not the case. This guide will explain you how to turn a very laggy experience into a good experience smooth gameplay.

if you actually have the requirement for the game
OS: Windows XP, Vista or Windows 7
Processor: Intel Core 2 Quad or higher
Memory: 2GB
Graphics: 256 MB Video Card (GeForce 7800 GT / ATI X1900) (or better)

The game support Directx 9 10 and 11 and is configured to choose the highest directx your GPU can use.

While that choice allow you to get the best visual quality it may tax your system way to much, in my case for exemple I ended up having arround 24 fps meaning nearly unplayable because my GPU support directx 10.1. But while it support it, my ATI 3870 doesn’t seem to be able to answer the higher demand of that directx and this is the case for many people. The solution is fairly simple.

You go in “My Documents” folder then “BFBC2Beta”. Open the file “settings.ini” with the notepad.

Go to the like DxVersion=auto and change it to DxVersion=9. Save the file and launch the game.
This should allow you to play in the less demanding directx the game support and increase significally you fps. In my case it went from 24 to 49 or more.

Also you may want to disable Bloom by changing Bloom=true to Bloom=false. The bloom in the game appear to be too intense for the eyes of many people. it can be blinding… So having bloom disable may increase performence and make it easier for you to spot people.

By default HSAO is set to false, but if it is set to true you may want to put it on false to increase performence.

Finally if your still lagging after all that, you may want to try to turn everything that is on High or Medium to low.

If you still lagging after all that… well you may need to buy a new GPU after all or new computer and I recommend you to check out my Hardware Guide.
