Well, when did you suffer from the problem (ie which FS version) and was it on specific maps or servers?

A few issues have been fixed, such as Yavin for nvidia users. There was also a FS common problems fix guide published in the news section a while back. I'd say give it a try, if you have issues report back with as much info as possible and we'll try to help out.

You have to give us more detailed information on what exactly the problem is that you're having before we can help you.

A good place to start would be to post the screenshots of your issue like you suggest in your first post.

So what exactly is happening here, you're getting slightly weird blocks of colour? Is it preventing you from joining on-line games? Does it happen constantly, or only after a while? Does it do the same thing with BF2142?

Have to admit that is one I've never seen before, looks like some graphics card error though, like it is glitching because it is overworked or something. Is it an older card?

The specs of your machine might be handy too.
