Yes.
DirectX 10 (comes with Windows Vista) is not backwards compatible with earlier versions of DirectX, so calls to older DirectX functions will be handled through an emulator.
On top of that, Windows Vista itself consumes a lot more resources (RAM, CPU cycles, etc.).
Of course, if you have a very powerful computer, you might not notice the performance degradation, but it certainly will be there.
I find a lot of these Vista comments incredible. Has anyone here tried a recent version of Vista? First of all, my machine specs:
AMD Athlon 2700+
1GB PC2700 RAM
Radeon 9800 Pro 128MB
20GB partition on a 180GB Seagate SATA hard drive
I build this machine around 3 years ago, and Vista RC2 runs absolutely fine. Moreover, Civilization 4 performance is equivalent to XP as far as I can tell. A game with 10 civilizations on the 2nd largest map size starts out fine, and becomes slow in the modern era on _both_ operating systems. And it's not like my parts are bleeding-edge; I can't even find my 9800 Pro on graphics card comparisons anymore. Even Quake 4 ran with decent performance. If you're that worried about memory usage, disable services like Windows Search, Windows Defender, DWM, none of which exist on XP.
Regarding "Five reasons to hate Windows Vista", I find a lot of those points nonsense. As I've said earlier, 2GB is not required; I'm running with 1GB fine. I don't understand why he's bashing photo sharing. If he doesn't use it, fine, but don't bash a feature others may want. I share photos with family members all the time. And software compatibility is quite good. Worried about possible game compatibility issues, I tried 20+ games on Vista, and the only one with problems is Alice. Civ1, Civ2:MGE, Civ2:ToT, Civ4, Civ4:Warlords all work fine (I don't have Civ3). His last two points basically boil down to "Upgrading has problems although I can't name any specifics with Vista, and Vista doesn't have anything I like."
Take a look at the
features new to Vista. If there's nothing compelling there, then by all means stay with whatever OS you have. But there are enough features I like that I'll be upgrading.
