No I dont get anything like that, for me its smooth as it can be at 30fps, I literally feel no lag at all. You have to remember people blow shit way out of proportion on here, a small issue becomes "gamebreaking". Anyhow, thats my take on it, no issues for me the game is smooth and highly playable. I do notice the lack of pro patch even though im on a 1080p tv though.
Just because it doesn't bother you doesn't mean everyone should feel it's fine.
Stay pure! I am!
I was going to go no alien mods, but it seems like there are areas you need alien mods to reach, so think I'll make an exception for those mods. Think turrets still see you as friendly with one or two alien mods, too.
