After an hour or so of game play, a mammoth's fur, an NPC's outfit, or even a door, whatever, shows a texture glitch. The usual effect is the entire texture is replaced by what I would called a texture replacer because the proper texture can't be displayed. I see instead a very lo-res glowing light purply-blue texture. Today, an NPC's head was a bright yellow knob missing all detail. After I notice those kinds of events, a CTD follows in a minute or two. I usually try to perform a save before the expected crash but am not always so lucky.

This shouldn't happen. A TES5 bug maybe?

Today, my room temperature is about 26°C, a tad warmer than earlier this week. Possibly, my vid cards are overheating. Any ideas?
