That may be true, but it is a 2007 era CPU. Even at max overclock (around 3.57 GHz air), it is still below an first gen i3 with mild overclocking
Why does Dolphin run faster on WinXP than on Win64

Can you test both OS's on the latest dev build of 4.0 x86? That will give a true idea of how well the two systems measure up.I downloaded the latest build for testing: dolphin-master-4.0-399-x86 In Windows 7, with either OGL or D3D (11), I get between 30-40 FPS in SCII, which is quite unplayable. In Windows XP, I can't launch Dolphin because I get a message: "this is not a valid Win32 application", even though it is the x86 build, so I can't test back-to-back. Does it seem as though I should be getting more FPS with my Dual Core 3.0 GHz and GTS 250? Would the card being Dx10 be causing an issue (even though OGL is as slow as D3D11)? Sure, getting a faster processor would probably resolve this but then I wouldn't be posting. I'm just trying to understand if I could possibly have something set up sub-optimally in my system that is holding performance back. I'll make sure I have my run-time libraries and drivers up to date. In the meantime, if anybody can think of something I can check I'll appreciate your feedback.

That's odd. Can you try the 4.0 or 3.5 master build on both?
Your GTS 250 is capable of handling some upscaling (around 2x w/ some AA), so its not an issue. Older revisions of Dolphin will run better on Windows XP because that was what it was optimized to, so you will likely see the better performance on older revisions under XP. Newer versions sacrifice some speed for better accuracy, and have been optimized for newer instruction sets (AVX, SSEE 4, etc) that your CPU doesn't have, and are more optimized for that precision under Win 7. On Win 7, make sure you're using high performance mode under Power Management (I'm not sure if that will have any effect, though.) Also, try using OpenGL, and enabling Vertex Streaming under the game's properties. P.S.: Do you have OpenCL turned off and OpenMP turned on under hacks? 11-18-2013, 11:22 AM
So the last I did was to update absolutely everything: nVidia driver, DirectX (was updated already), VB runtime and Windows. Only VB was significantly out of date. I did not see any improvement with the recent versions of Dolphin although the old x64 version I'm using with Win7 seems a bit more consistent now with its framerate so I'm back to to where I was with Win XP.
I still can't explain why the x86 version runs better in Windows XP than on Win7 by a good margin and feel that if I find something there, it could yield further optimization of the x64 version.

It's good that you're looking for ways to improve, but some may be speedhacks that were removed.
It's good that you brought you Windows 7 up to were you like it. 11-18-2013, 01:21 PM

The speed hacks would explain why recent versions are slower than older ones but the puzzling part is why the same version runs faster in one OS than the other. Is there a performance penalty for running 32-bit applications in 64-bit systems?
