Re: Tactics cannot be very important for chess

It is a cowardly way to play chess. If I think I face an equal, I try to make a tie, and if I think I face a weakling, I do not respect them. I think that it is better to go for the win at all times, and maintain respect. So, for instance, if I do not build a wall but leave holes, then we can both ...

Re: PGO compile on VS2019 not working

Sorry for the late reply, I'm having some health problems that are limiting my work with a computer screen. Thanks Joost for your kind offer. Ed Gilbert also was having exactly this same problem with VS2019 and he gave me a tip that I will try as soon as I get better. And it doesn't look there is a ...

Re: PGO compile on VS2019 not working

I created a fresh project from scratch in VS2019, but the problem continues, no .pgc file is created.
I don't know what to do anymore.

Re: PGO compile on VS2019 not working

So this is a whopping 13.5% improvement for the move-generator/do-undo-move logic. A strange thing is that when I specify 'std:c++17' for language instead of the default this gives me about 2% improvement, you would expect that this has influence on the parser only, but it seems to change something...

Another thing I can think of is to make a completely new project file with VS 2019, in the past I had some issues when I used project files from VS2017 converted to VS2019, but maybe you did this already.
Ok thanks for the tip Joost.

Re: PGO compile on VS2019 not working

I just looked at it, although the MSVC version is at 1.42 the dll is still called pgort1.40.dll, it has a size of 49.016 bytes. I remember in older versions of VS 2017 there was a bug and you had to copy that dll to the location of the executable, but that is not necessary anymore. It can be a bug ...

Re: PGO compile on VS2019 not working

I use exactly the same options /LTGC /GENPROFILE to instrument and /LTGC and /USEPROFILE to optimize, if you use the PGO options from the build menu I suppose these are automatically set for you. Right, and the engine works very slowly, so it confirms that the instrumented compilation was successfu...

Re: PGO compile on VS2019 not working

Maybe the dll file is too old? VS 2019 is currently at v1.42. I don't understand why you have to use a separate dll anyway, maybe the community edition is not supporting PGO? I use the profession edition, and I don't have issues with PGO at all. You have the enterprise version with the same version...

PGO compile on VS2019 not working

Hi, I'm trying to make a PGO compile of my engine using Visual Studio 2019 but with no success. I copied the pgort140.dll file from: C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.22.27905\bin\Hostx64\x64 to the folder C:\Profound\ wich is the default folder for my e...
