Silly question I know, but how would I recognize an Out of Memory Error on the card?
After updating my drives, downloading Enhancer, and configuring IAW with NickN's guidance, I do seem to see enhanced performance. It also appears that the 3D detailing is improved, although that could be wishful thinking on my part.
However, when switching view the screen throws up a texture and locks on it for a moment (usually a gridded pattern repeating the texture).
This seems to be a likely problem with memory, but before I proceed to attempt adjustment, I'd like someone else's opinion.
