Yeah, go to the videocard maker, AMD/NVIDIA, to get the drivers for your card. I don't use AMD so not sure of their website but NVidia is NVidia.com. yeah, just make sure that the video driver is up to date, your windows upates are all complete, the punkbuster, also check your firewall. The firewall may cause issues for the game too, so go into the parameters for it and select the program and choose allow to bypass issues. Those are all I can think of to alleviate issues. I am only currently using the gtx650 card from NVidia which is more power efficient than powerful so I don't try to up the vid capacity and such. lower the vid settings on computer and this should also help.

hopefully you've made progress on this by now but AMD's site has an autodetect to tell you what specific card/os version you should install, and you definitely need to upgrade your memory. The issue you might run into though is if you're using a 32-bit Operating System (OS), (which it sounds like you are because of the 3.3 GB thing), It won't address (utilize) any amount of memory above 4 GB which means you'd have to upgrade your OS.

@lolmamalol:

No man there are no stupid questions. You can find drivers for your card here:

http://support.amd.com/en-us/download

Simply choose your card model, operating system and update your drivers. Looking at your specs you would benefit from the upgrade. You need new GPU and more RAM. It will not hurt to install new drivers though.

I would consider saving some cash for new GPU. Ask santa to get you one. I mean you can get good GPU relativly cheap. New Nvidia and AMD cards pushed the prices of older models down.

Good luck !

BF 4 is very demanding game. I could play it BF 3 on ultra and BF 4 was running really slow. It was lagging, freezing and I could not enjoy it at all. If you upgraded your graphic card try to install new drivers, it might help. Maybe its worth to think about new GPU. I bought one and BF 4 runs really well now. The only thing which annoys me is how slowly levels load. I have 6 GB RAM only and every time I join the game with some considerate delay. I need to buy more RAM I think. Coming back to you, what GPU you have? Try to install new drivers and see whether this helps. Also check how fast the game runs on your machine. Lunch console and type in: perfoverlay.drawfps 1 to lunch console type in: ~. If the game runs below 30 your problem is a GPU. hope this helps a little.

I use Nvidia so don't know the appropriate matches there for vid cards but if you can play bf3 on ultra with no problem, then bf4 should be the same. though from my game review don't buy it yet. Way too many issues and problems that were never fixed or even occurred in the beta are present in game. Just give it a month or so.
