Please could anybody tell me whether I can play LA Noire well, especially as I've installed it on an external hard drive. It does play but it's very sluggish at the lowest of settings, and even gets stuck.The response on- screen is at times minutes after the button is pressed. Would the graphics card crash if I continued or is there some other problem?Could anyone help?Here are my specifications- ACPI x86 based PC,ATI Radeon HD 5400 series display adapter,Generic PnP Monitor, Intel(R)Pentium(R)Dual CPU E2160 @1.80GHz, 3 Gb RAM, 32 Bit System, Windows 7 Ultimate Service Pack 1
