crosshairs and opinions about 800x600 resolution
good for Catch the Beat as long as it's not AR 10/above, pretty shit for osu standard (somehow it's jittering while the native reso does not), can't say about Taiko, also pretty shit for osu mania, you only hurt your eye if you use 800 x 600.
800 x 600 only good for CTB as the feel of ryu(the catcher) feel more fluid compared to other resolution but it's not competitive because you can't see the fruits beyond AR10.
