Ok I just gave it another go, and actually had a better game. But I still don't like it on the PC. I came top of the server as well so it's nothing to do with my ability to play the game. However even though I came top I still didn't really enjoy it.
The frame rate is a bit iffy, and turning it down to low doesn't seem to do much I think it's pointless having a "settings" option when the highest vs. lowest settings don't really change anything
It is a lot buggier and choppier on the PC, hit reg is also a lot more obvious - it's bad.
And as the person above me said, the pc fanbase doesn't seem as willing to work as a team and get to the objective, they would rather camp.. when they are ATTACKING lol or they would rather just run AROUND the objective rather than go TO the objective lol.
Plus the very feel of the movement, along with the big guns that take up a large portion of the screen etc, it just doesn't feel like a PC game. It's clear that they originially made this on the Xbox 360 and then ported it to the PS3 and PC.
I think the game is "ok" on the PC, providing you have a top notch PC to play it at, a decent server that doesn't lag, and a group of people who are willing to complete the objectives.
