I use Visual Studio 2010 Enterprise! In a Visual Studio project barswf_cpu.vcxproj I've saw this <ClCompile> <Optimization>MaxSpeedHighLevel</Optimization> Apparently this value is not valid, https://docs.microsoft.com/en-us/cpp/build/reference/o-options-optimize-code?view=vs-2019 I've replaced that (MaxSpeedHighLevel) with: <ClCompile> <Optimization>MaxSpeed</Optimization> Now compiles, the problem is that speed is of 45 MHashes/second instead of 60 MHashes/seconds (in already compiled exe by someone else) - so the speed is 25% slower. Anyone know what is with MaxSpeedHighLevel ??? And …
