Beyond that I haven't a clue.
A clue...

I believe the windows 8 requirements are lower than window 7, so that isn't an issue either.
While it seems remarkable that you can walk into any store and buy the latest/cheapest Windows 8 machine and CM works just fine, the real factor is that the program is not being written for the average machine that is sold today. Nor the cheapest either. Use of multi-core CPU's and other issues are an example.
I have run the game on my old '06 Gateway fine. It's a PentD 3.0 GHz, WinXP, 32 bit , 4 GB DDR2, SataII HD with a low buck 1 GB Nvidia. I installed Win7 and it also ran fine for awhile but started in with the error mode.
I have Win8 (32 bit) running on my 'junkyard dog' PC in the basement. A better system based around a higher end dual core and uses DDR3 memory (4GB) and a better 1GB DDR3 vid card. This runs fine and maybe too fast since getting down to ground level is touchy. But, again, it's old hardware running Win8.
So, I don't really see the wonder in your post. To me, it actually is highlighting that the game is behind the times as far as common hardware. I deal with many people tossing all kinds of equipment in my business. Much of the stuff is best sold as scrap to the 'gold-rats'.
While it probably is too soon to write games for 64-bit operating systems, it is certainly past the times where "Pentium IV 2.8 GHz or equivalent speed AMD processor or better" is the suggested" (single core?) is the hardware that many people have. That is a crappy office system in my opinion that would be seen in a workplace.
As far as operating systems for the PC, this may be a golden time. That is, Win7 and Win8 will probably mature to be the next 'XP' standard. maybe a window of a few years at least where games can be developed without a Gates melt-down.
I have removed all XP systems from my house and all 'live' PCs are running win7 and win8. I have seen win8 crash dumps on the 32-bit system with the demo. I have not installed CM on the win8 64 bit notebook yet or the wife's win7 64 bit notebook.
