"Missing Polygons" artifacts after graphics driver update

I’ve never had any problems with my graphics “card” (it’s an integrated, but it was fine) until a few days ago, when I updated the drivers. This started happening, it only seems to affect NPCs and ragdolls, props are fine.

Also note the “stretching” going on too

Is it a problem with the drivers, or something more sinister?

Close this, I found out it was the drivers, I reverted back to 12.2 or whatever and it’s fine:
