Sorry for the late reply...
I'm Austrian, so excuse my poor english...
I hope you can make sense of this:
I run 9.12 drivers...
Ok you go into CCC.
Graphics > Desktops & Display
At the bottom you will see a icon representing your LCD. Note the little arrow. Click on it...
Select configure...
There will be a section "Image Scaling" and a tick box "Enable GPU scaling" and 3 settings...
Now by default the tickbox is grayed out. This is just a bug...
What you need to do is lower your desktop resolution until it's not greyed out anymore... (Meaning you lower your desktop resolution BEFORE you go into CCC).
Not every desktop resolution does the trick. In my case it was 1280 x 768...
Then tick the box and select "Use centered timings"...
Click ok, set your desktop resolution back to native, and you are done!
Let me know how you go!
Thats how I play BF2142...
1024 x 768 on my 18.5" LCD (1366 x 768) native...
I have no opted to run 2x AA but Super Sampling... Looks nicer than 4x MSAA when in motion... 4x MSAA gives you slight shimmering in some areas when the image moves.
EDIT: And regarding the ongoing debate: Obviously a higher resolution will allow you to see more details. And if I had the choice I would get a Full HD screen and a Radeon 5870 or 5970. BUT I am cheap bastard and hence I game on a 18.5" LCD with a Radeon 5750
If you don't game you would be nuts not to buy a Full HD screen. They are cheap as chips and any onboard soltuion can drive them just fine.
