Is it just me or do the colors seem to "pop" more in your screens? The Dota 2 I've seen before seemed a bit washed out.
Those bf3 screens were taken while experimenting with sweetfx. Dota 2 on the other hand is regular vanilla, I checked to see if downsampling changed the colors noticeably but it didn't, could be the brightness slider I remember that affecting the contrast/color of the game a lot.
