Yes, I had a sluggish gameplay if full map show, but no problem if map wasn't show much and fog in start of game, I think it's had to do with map show to you, uncover black fog, and it's become more of sluggish even it's sliggish tiny map as well if show full of map...at least my case..

Windows performance report? I did try closed any program that not need in background by using a task mangers in tab+ctrl+alt+delete (window 7)

I meant the windows experience index base score under performance information.

It tests your RAM, graphics, processor and HDD speed and gives them a rating. You will come to know what things are running good and what things are running less good - which may indicate a problem.

Don't forget, the report will not automatically change when your computer status changes. You have to run a new test if you want to see if anything has gone bad since the last test was run.
