OK djvj, with your exact settings, at windowed resolution of 1280x1024 I get about 31 avg fps in town with lots of mobs. when I turn radar off, I get about 35 avg fps. If I select the search box it drops to 7 fps until I return focus to VG. I am using high performance settings.
Now with balanced settings:
With no radar I get 27 avg fps, with radar I get 25 avg fps.
Hmm...you said you were facing a wall right? And not moving I assume. Well something is fishy, cause if your not moving the radar only updates once every 4 seconds or so. Now when your moving, the radar updates about 10 times per second.
Try using AutoAlign = 2 and intMilliSecsToRun = 200
That will make the update area smaller and it should still update about 1 time every 4 secs standing still but will only update 5 times per sec while moving. If that doesn't make a difference you have something else going on with your setup.
Hope we can help you figure it out
