I have Windows XP 64-bit, and am having a some weird issues with a 64-bit build of VirtualDub. In the release notes on SourceForge, it it says that the 64-bit version was compiled specifically for CPUs that support AMD64/x64 long mode. How can I determine if my CPU supports this?
From the VirtualDub site:
In essence, all modern 64-bit processors. ("Intel Xeon CPUs with EM64-T" includes Core 2 (Duo), and similar)
