Guild Wars 2

So i have Acer Aspire 5750ZG and it should run game well,but every time I enter
game it’s start lagging and graphics are weird because all kinds of props randomly spawn
and than dissapear,pictures are sometimes blinking and some strange green,gray,yellow
and purple lines are flying in game.I thought i had old video card drivers,but after
updating nothing changed.Programs and websites that scan your computer and
compare them to game requirements say that i douldn’t have problems running the game.
Could you plz help me?

Make sure your not using the integrated graphics and actually using the Nvidia GPU.

Do you get weird colors/lines flying around in other games? If you don’t have another games to test, run 3dmarks to test.

since you updated drivers, try reinstalling/updating DirectX
