[baschi]

hey guys! i have a strange problem: i just changed my graphics card from an old ati hd4850 to a new gtx 570. the new card is operating normally, but since the change, PR wont start... no error message no nothing...
i also tried reinstalling with the 3 installers: still just wouldnt start....

More specs pls.
Btw you wont see any difference in fps with those gpus.

You mean that when you click on PR, you get no indications of it loading, no splash screen, no nothing?

or do you mean you CTD when you try loading a map? if it is the latter go to my documents/battlefield 2/mods/bf2/ and delete everything in there, that will caues your graphics shaders to sort themselves out, which might be your problem.

i meant that theres no splash-screen, but alright now
