Do not know if this will help or not.
If it helps 1 then the post is worth it.
I reloaded the Steam game of SHIII.
Kept getting the cannot enable 3d crud.
I have a high-end system unless asked I will leave it at that.
I have a 4K 32 Inch computer MONITOR... "Not a TV..."
I set the 32 Inch for 1024x768.
The game runs in BIG WIDE SCREEN!
This is all vanilla I played it big TIME back in the day.
At 66 years old everything in nice and BIG WIDE screen!
