This is a heavy edit of GTA IV's original timecyc.dat, weather with more appealing lighting, skies, and more.
A comparison of GTA IV's original Extrasunny weather vs mine.
It's as blurry as the original timecyc.dat... You can always set the definition on. If anyone knows how to adjust the degree of bluriness (not the distance of the effect), PM me or whatnot.
