I get lag over cars on some tracks not all, its a small hiccup. I don't know why but its like the frames dip below 30fps while everywhere else gets 60fps. My pc specs are: CPU: AMD Fx-8350, GPU: GTX 580 1.4GB, RAM: G.SKILL Ripjaws X Series 16GB. I can more than handle Rigs of Rods maxed out but I need to know what to turn down specifically to fix the hiccup I am having and keep everything smooth, or at least be told the reason behind it. If anyone could help I would greatly appreciate it.
