Not sure what all this is about. I'm using a 2.8 GHz Dual Core running Windows 7 Pro 64 Bit. I was abit surprised, but Mechwarrior 4 runs just fine. That was released on November 24, 2000. Almost 11 years ago. No compatibility mode.
I just build a new computer for a friend this Spring to replace her 7 year old Dell. The new computer is slightly better than mine. Same OS. I installed all the software that was on her old computer. A good bit of it was from 1995 to 2000 release programs. All of it ran, no issues, no comparability mode.
