it's both. i try both online and offline. online is more bearable but when i get online it gets unbearable. what do you mean exactly by defrag? i am relatively new to pc gaming.

What kind of video card is the RS880?? Whatever it is, it looks like it isn't meant for modern games.

Yours only has 128 mb dedicated VRAM. Looks like the RS880 is integrated. You need a good dedicated video card. Canyourunit is not the most accurate site in the world and it gives you very little idea how well your specific computer can run a game

I don't know whether you mean online or offline, but with offline, it could be any number of things (i.e. other programs running, other users, security programs, you may just need to defrag) If it's online it could be any of that, the internet, or steam.

> scan system for viruses

> defrag registry using reliable software such as reginout

> uninstall unwanted programs and run disk cleanup

> defrag your HDD

Upgrading RAM is also helpful. thanks
