Are you running at 1920x1200? If so, that might explain why FOV 100 looks better for me. I'll not go up to 110 though. I don't have many custom maps installed yet, so once I get some of my fav maps like DM-Anubis and DM-Beholden, then I'll know which setting I like best. I was using DM-Liandri, but I couldn't really get a feel for it; I'll probably have to test 4-5 maps to be sure.
