for me it runs well now at 1600 pixels , no anto aliasing all on low , except textures and it still look well. gameplay and lagree is top priority over grafic.
i get 58 fps now on my radeon 7800 seris, also never had bad lag issiue but i always sort players after ping and have kinda fast internet. sort players after ping should be the default setting and the room should remember this setting , so you dont have to click 7 times r1 after every match to sort the players
so if you have lag reduce the grafics (especially the resolution) it will effect the other player too. before i tried to play on 2560 pixels with good setting no way to play lagfree , the performence could here and there be imporved. hope this come when the versions for the old consoles get released
btw , patch fixed the dead woods error i had
