Hi,<br><br>There was a comment from ryan:<br><br>>> Are you saying the ut3beta dedicated linux server needs the SSE2<br>>> instruction set?<br>><br>> It's built with -march=pentium4 -mtune=pentium4 -msse2 -mfpmath=sse ...
<br>> so it will use generic instructions that were only available on P4-level<br>> hardware, and sse2 for all math operations.<br>><br>> If you're still on Pentium III level hardware, it's time to upgrade.
<br><br>I think the last phrase says it.</blockquote><div><br><br>As someone else pointed out, calling an Athlon XP processor (which is what that thread was about, mostly), "Pentium III level hardware", is inaccurate and fairly harsh. My question, which appears to have been unanswered to date, is that: does it require sse2 instructions? Does the code actually require sse2 instructiosn? Stating it's built with that by posting the gcc options doesn't tell me the actual program requires it, just that whoever compiled the code made it require sse2 support.
