Are there any problems with Windows 7? (And if there are any, how are they to be fixed?)
I don't recall any--and I'm now running the game with 8.1x64 with no problems. You're perfectly safe...;)
Edit: Thought I'd add this little tidbit here as my post about it is dropping down the page very fast...;) FSAA in M&M9 is easily obtainable
. Just disable "optimized surfaces" in the in-game graphics option menu, and force FSAA from your driver control panel. Gawd, what a massive improvement in the game graphics! It's such an improvement it really isn't an option, imo--it's mandated if you want to enjoy the game graphics at all.
"Optimize surfaces" isn't needed these days at all, and turning it ON means you lose the ability to FSAA the game by forcing it from your driver control panel. You can still force it with the option on, sort of, but you'll get a horrible-looking checkerboard pattern
that overlays every 2d screen element. Just turn it off and turn your FSAA on. The game looks great @8x FSAA EQ.
