Hi guys so i was having anti aliasing problem before but i think i was being paranoid or something idk(probably cuz switching 720p to 1080p). When i watched some other guys on youtube i made a comparison and it's all normal. So my issue is when i stand still in games I have sharp view(little jagged edges) but as soon as i start moving(running,walking) somehow i get little bit blur on all edges but still better quality overall. Objects have 0 jagged lines and anti aliasing seems work better then before when i move. And when i stand still and start moving game feels weird and i want stable quality. I tried testing with Fraps,Relive and i have this problems in videos too. I don't really think it's a monitor issue but i wanted to ask you guys. Help me out please. Thanks!
