I'm facing the same problem whenever i try switching to Nvidia graphic option. the game runs well on integrated graphics. I've Nvidia Geforce GT540m Cuda 1 GB graphics card in my laptop. i recently re-installed the game without installing the latest patch. its running fine but whenever i install the latest patch i get the blank screen. can anyone help?
