Finally I've got a good internet 30mb/s so download/upload is not a problem anymore. I just started to have some fun with graphics improvements. I used textures from Photo Realistic Zone, Autunm Aurora and Lost Alpha. I'm forcing 4x standard Adaptive Multisampling and Morphological Anti-Aliasing through Catalyst Control Center (same for nVidia but that's FXAA instead of MLAA). How do you like it?
