Looking at the past 3 ports on PC...Most Wanted,The Run ánd Rivals all one of the worst PC ports and they didn't bother to fix it. Also capping a racing game to 30fps is utter nonsense on PC.
Still playing Hot Pursuit 2010 because that one is still working solid today.
Most Wanted was I great I thought, looked really good and performance was excellent on my system at the time (GTX 570).
Most Wanted 2012 was great on PC. It looked great and was demanding as a result, but it wasn't horribly optimized. The visuals you got for the performance you gave was reasonable.
The Run wasn't a Criterion or Ghost Games developed NFS. That was Black Box, and they're not on NFS anymore.
Rivals wasn't a bad port, so much as some poor decisions were made. The game looks great and holds 60 on good hardware, but it could be optimized better, and it sucks that it's framerate isn't unlocked and that it's always online.
The Criterion/Ghost developed NFS games aren't poor ports. At worst you can say they suffer from some bad decisions, but nothing like awful power/performance ratios.
