Taking pictures and making them into bmp then converting them to png look much better than these super compressed jpegs...You can spot it easily by comparing my first pics to drewboi's where the MC jumps on the ghost...MC is blurred to death while his edges are pixelated.
Although, uberscreencaptool does only do jpeg compression so I dont mind too much...If it did however, I wouldnt let you dishonour picture taking in halo2 like that
Also, kirk, which picture shows it as being smooth? As Im saying above it may just be the quality of the pic. I do agree with you though, that halo2 bump mapping looks ugly sometimes.
