Game developers understand that there are many laptops and some desktops using intels integrated graphics, so they cant ignore them. There are some gameplay videos on youtube of highly graphical games being played on intel 4600 hd graphics such as farcry 4 and Battlefield 4 on an i5/i7 processor and all of them run smoothly (around 30 fps).Yes they are on lower graphics settings but the game still looks good. You will be able to play most games with this setup. Yes it supports direct x 9 and any screen resolution except maybe higher than 1920x1080.
