Is it possible to find out if the current architecture supports hardware acceleration in Framework 4.5 - 4.8? In Core/Net I use System.Numerics.Vector.IsHardwareAccelerated.

What I have tried:

In Core/Net I use System.Numerics.Vector.IsHardwareAccelerated, but it is not there.

According to Vector.IsHardwareAccelerated Property (System.Numerics) | Microsoft Docs[^] it is available in .NET Core up to version 3.1.

This method is only available in core, but how can I determine if hardware acceleration is working when this method is not available? I have some code and in both 4.5 and 4.8 frameworks it is much faster when compiling 64bit, so it probably uses hardware acceleration. But something more explicit would be useful. I'm currently only using the preprocessor code:

#if BUILD32
//use Framework function
#else
//use optimized hardware acclerated function
#endif

The documentation says that the framework uses hardware acceleration where available. So you do not really need to worry about it.
