Surprised To See That In-Game AA Works....
 

....and works well. I'd read a couple of posts where guys couldn't get Anti-Aliasing to work in game and were being told to force it through the Nvidia control panel. I did it without even trying the games AA.
Always saw some jaggies, but not bad, so figured it was something I had to live with.
I finally decided to try SH5's AA slider. Turned it off in the panel and pushed the game's slider all the way to the right.
Damn. Everything is all nicely smoothed out now. Sub's railings, wires, cables, building roofs....etc. Should have just tried it from the beginning.
This is one of the best looking games I've ever had on my PC.
