AutoCAD 2010 gets more power from your CPU

The new AutoCAD 2010 should use the SSE2 extended instruction set in modern CPUs. This instruction set allows hardware-assisted (read: faster) computations of some mathematical functions and transformations which are quite frequent in CAD applications. Software source-code compilers have usually a simple switch for support of the SSE2 set.

The SSE2 set is supported in Pentium 4, AMD Athlon 64, AMD Opteron and higher processors. There is little chance you install AutoCAD 2010 (or any other 3D CAD) on a PC older than that.

I haven't seen any benchmarks on how much faster will a CAD software run with SSE2 enabled but this is one of the good ways to make a software faster.

But remember - if your AutoCAD installation is refused or you get "The application could not be initalized" erros, make sure you have a CPU with the SSE2 set supported and enabled.
