Okay I have an Alienware M15x with the Intel i7, Radeon Mobility HD 5730 video card, and windows 7. My drivers are up to date.
I got Skyrim and played in on High setting for about a month with no problem... over 65 hours gameplay and no problems what so ever. Then, I update my display driver and try to run it, and the frame rate in insanely low. The game auto detects best settings at High, but is only barely smooth at Low settings. But, when I updated my drivers, in the system information is said my video card was something like a 6900M/5700 instead of the regular 5730 HD it had listed earlier. So I rolled my driver back to see if it would fix my problems, and it didnt. Skyrim is still low FPS. I can run WoW and Runescape no problem... but Skyrim is flat out glitchy now and I cannot fix it. any help?
