I've got the Acer x1430 which I know by all means isn't going to be the best computer in the world for running games but I know someone who has practically the same machine, except mine has slightly better specs in ,what we can see, as every single area of the computer. He runs at 4 1/2 to 5 star performance. Is there any computer settings, or any other reasons, that might be restricting mine from running properly?
