But other than a small increase of FPS that W7/Vista may give (0.5 - 2 FPS) there isn't really much of a difference so long as you have decent hardware. Technically you should have decent hardware to run the emulator to begin with unless you like hindering your gaming experience and enjoy playing a slideshow. Windows 7 has fairly low overhead and performance if comparable to if not better than XP.
I've been using Windows 7 since it's release and it has been good to me so far, quite the improvement over Vista.
I tried both. And sorry i was wrong, somewhat games work faster some slower, depends on your hardware and the rev ur using
With Zelda TP, Xp 32 was better than Win 7 64. We are talking about a difference of 2-3 fps.

The only answer that gave the right technological answer..
Though, in fact, XP has less background and system processes, drivers, than Vista or Win7. I can boot to XP from null power to desktop in about 15 seconds, whereas Windows 7 will take about 30-40 seconds as well.
I stick with Win7 for compatibility issues though, and usage of DX10
I thought XP ran cpu cycles on a workload faster and more efficient then windows 7 on multicore cpus but 7 is more optimized when you start having higher numbers of CPU's in the multicore cycle.
clearly:
XP 32 BIT
Vista 32 BIT
Windows 7 32 BIT
these 3 make the same performance in dolphin....
and now:
XP 64 BIT
Vista 64 bit
and
Windows 7 64 BIT
have the same performance in dolphin!
64 BIT system against 32 BIT system... 64 will definietly give more frames out!
If you have an X64 hardware then you should take advantage of it.
it does not matter if you have XP, Vista or 7 on your PC... (32 BIT)
all the will make the same performance!
X64 systems will beat 32 bit systems, does not matter which one. (XP, Vista or 7)
and directx10 or 11 will not change things... dolphin is only using 9!
will dolphin use DX10 or 11? i dont know... but if yes, vista and 7 will be faster! that is the only thing what makes vista and 7 different in using dolphin emulator... otherwise it is the same, except using X64 or 32BIT (X86) as a operating system.
it is right that vista and 7 are optimized for dual core's or quad core's. but dolphin is only using 2 of them! and XP can handle that very well
.
if 4 cores are used in vista or 7 (on XP too), you can do this:

you can choose which cpu's are should be used from dolphin!
2 at 100% will give more frames as 4 at 50%...
by rightclick on the task and CPU affiliation.

As long as you have good hardware, Windows 7/Vista will be as fast as XP if not faster. Compared to Vista Windows 7 is quite a big improvement, someone posted on my forum with pictures of Windows 7 running fairly well on 96 MB of ram in VMware.
On my system it takes maybe 10 - 25 seconds from boot to desktop, probably faster if I had no password and my hardware wasn't giving me problems.

Ya, DX version doesn't matter unless in the future, a compiler makes dx10/11 plugin. Dolphin is only utilizing dx9 plugin draw commands to graphics card. Having a higher version doesn't help anything.
I would call difference between 32 and 64bit OS debatable. Having both types (vista32, win7-64), results are mixed. On games such as super mario galaxy, the difference can be drastic (almost 10fps). On games like smash bros melee or new super mario bros, there is 0 difference in speed. So that also strongly depends on how demanding the game is.

x64 OS is always an advantage...
64-bit doesn't automatically make "everything faster" or give an 'advantage'. It totally depends on how many cpu cycles the program demands and how many calculations per second dolphin.exe utilizes for emulation. Especially with less than 4gb of RAM, there is no point to have 64-bit OS.
I use 64-bit 90% of the time, and yes, it has about 5 to 15 fps differences depending on game. Then again, with titles like Zelda: Twilight princess, with my Vista 32-bit and Win7 64-bit, there is absolutely no FPS difference even in Hyrule field. It is completely subjective, and even false to think 64bit OS is some sort of gateway to better gameplay.
The bottom line: 64bit is better for some applications, and some emulators/games. If you have good hardware to begin with. But it doesn't by itself make anything faster.
Microsoft has
an article on 64-bit architecture and design. It should explain a lot. Unless a program and all it's components are specifically written for the 64b platform, there is zero difference to 32bit programs
