Onboard Laptop Radeon HD 7500G not performing like it should?

Hello everyone, i have a Samsung series 5 laptop with a A6-4455m cpu and a Radeon HD 7500G graphics unit. Unfortunately, i am experiencing some problems with this laptop. My computer can successfully run "League of Legends" however the experience is awful. Any 3D gaming experience is awful. At any settings my fps goes from 08 - 30. I looked at benchmarks and it turns out my graphics card can handle much more demanding games. I figured that my drivers are outdated. I decide to check what version i have under AMD vision control centre. Unfortunately, the program doesn't state any information about my GPU nor the version of the drivers. I decided to use Samsung's update checker to see if my drivers are up to date( AMD`s mobility program said it is not compatible with my hardware and software.) Samsung`s checker said it is up to date.
Why am i getting such bad FPS with my graphic`s card / laptop?

FPS i should be getting with games : http://www.notebookcheck.net/AMD-Radeon-HD-7500G.74861.0.html
People claiming that they get good FPS with league of legends with similar specs to mine:

Please, i need some help!

Edit: I would make a complete backup and try the AMD update, I doubt Samsung, like most laptop manufacturers, will update their drivers.

You should be updated to 13.1 mobility drivers, the differences are substantial.

As for legue of legends, their last patch 3.03 broke their graphics engine for many people (massive stutter for ATI, and very high CPU & gpu usage with much lower performance for nvidia), so don't base yourself on those results right now until they fix this.

Your apu should be able to run lol low/medium settings above 30fps sustained.

Hope this helps.

Thanks a lot, Yakk! Anyways, more recently i have been expierancing lag when browsing the internet. About 2 seconds into the lag i hear 2 beeps from my laptop. Do you think this is related to the outdated APU drivers?

I couldn't say if it is specifically related to the drivers, but it should improve everything overall. I know when I updated the drivers of the laptop in my sig, it felt like a new machine (that's without the ssd, with the ssd it just runs awesome).

For the beeps, your laptop documentation should indicate what the beeps refer to, if not, it may be worth a call or a search for your specific model.
