Pre-release tester with x64 Windows & SSE3 P4 needed

So.. my prescott isnt any faster running the 64bit? That really doesn't surprise me. This chip has just enough 64 bit to get by. Im pretty sure the later CPUs are much better dealing with 64 bit than this old p4. Mabey the Pentium D will score better.
When its installed. I will re-run the tests again.

Why? It's faster with x64 app. It just didn't feel difference between 2 x64 apps. But x64 SSE3 the best for him.
Jason G:
My guess is better kernel driver probably is a part of it (no legacy code or pointer address space conversion to go through either). Win32 drivers have a lot of legacy code in them to handle many diverse setups. 64 bit drivers can generally be leaner, especially WDM ones if available, and can assume the availability of SSE & SSE2, which means fast streaming loads, cacheability instructions and and non-temporal stores can be used.
Mike O:
So.. is there a team V8 64 bit for only SSES? One that works with CPU/GPU mod you did?
Also.. Is there a 64bit for the SSSES CPUs that will work with the team mod?

For normal AK_v8 (CPU) 64 bit SSE3 or higher only (because of library limitations, No Intel 64 bit SSE2-only CPUs were ever made AFAIK)
For Team mod (CPU+GPU), that requires the special builds of Raistmer's to function, so you'd have to check Raistmer's thread on his latest packages.

The question is who need such builds ;)
What host config you have to want SSE-only build for using with CUDA-enabled GPU ?? I though such configs just don't exist.
There is V10a for SSE3 x64 and SSSE3 x64 already, look corresponding thread.
