Im fine with 30fps but most of the time it seem to be like 25 or lower. The thing is that it totally slows down the gameplay. It works fine when there are no enemies but as soon as a firefight starts u see hiw rhe framerate drops.
The worst framrate i had was when u were in this restaurant and first met one of these huge alien robots. The fps did go down to like 10.
I hope C3 will not become a slideshow...
