Dota 2 lag on PC?

hello i have a laptop which was quite expenisive. It has an intel core i5 with intel 4000 graphics. But when start playing Dota 2 it lags terribly but most importantly the images are a bit blurry as in in can almost se ethe pixels and its just not sharp enough. Do i have to download a flash player or something? pls help :(

I think it's some sort of bug in the game since the game is techinicly not finished yet, i had the same problem when i went to test the game to see if it's any good. Everytime i join or start a match, during the first minute or so the game stutters like crazy for no reason

I have no issues playing Dota 2 on my PC or laptop (specs in signature).  The laptop I need to turn the resolution down to like 1300x750 (or something like that). 

The game runs flawlessly otherwise, no crashes, no studdering etc.  Once in a while there will be a server issue but that's online games for you.

As far as the game not being finished, it's more finished than 99% of games that are released on PC or even consoles.  New content is added all the time and they try to "improve" but it's clear the game isn't a beta.
