I saw the posts on the nvidia forums and even I was annoyed. I hate asking question only to get argument against ever answering it.
I have a Titan-X with 12GB of video memory and 32GB of system memory running Windows 7 64 bit and my Skyrim also runs fine. As expected, the video memory only shows about 4GB maximum being used according to diagnostics; Evga on screen display of video memory use.
When I reinstalled Skyrim I intentionally chose the highest quality settings for
Vividian ENB, the largest textures, and even
Dynamic LODs at the highest setting just to see how it would run. I use the frame rate limited to 58 fps but @ 2560x1600 often get only 40 fps with lots of snow or rain while moving outside in demanding locations like outside of Windhelm. Skyrim won't even run at these settings without your software.
Previously I had a GTX 690 with only 2GB of video memory and Skyrim ran well with your memory management additions. I wish I could send you this card to test with since it had Windows XP drivers although they weren't supported officially.
Thanks for everything Boris!
