App Claims to Blunt Intel's Compiler Edge on AMD Machines

A ominously named app claims to boost certain apps performance on AMD processors. Called "Intel Compiler Patcher," this app scans your machine for apps developed using Intel C++ compilers, and patches them to work better on non-Intel CPU platforms (namely AMD). The idea (suspicion rather), is that apps developed with Intel C++ compilers give modern AMD CPUs a performance disadvantage. The following is how the developer describes the app works:
The compiler or library can make multiple versions of a piece of code, each optimized for a certain processor and instruction set, for example SSE2, SSE3, etc. The system includes a function that detects which type of CPU it is running on and chooses the optimal code path for that CPU. This is called a CPU dispatcher. However, the Intel CPU dispatcher does not only check which instruction set is supported by the CPU, it also checks the vendor ID string. If the vendor string says "GenuineIntel" then it uses the optimal code path. If the CPU is not from Intel then, in most cases, it will run the slowest possible version of the code, even if the CPU is fully compatible with a better version.
We don't have an AMD machine at hand to put our benches ourselves, and so we invite AMD CPU users from our community to post their results by using this "patcher" at their own risk.

I couldn't get it to run, when patched and I saw more variance than that on unpatched runs, I have as of yet to find anything that will run without error after being patched on Windows 10.

Have you tried opening the patcher with "run as admiistrator"? That's what I did.
