Re: New computer chess forum

It's not the forum, it's some of the people. It's like saying the politicians suck! But wait where do the politicians come from? They don't come from another planet, from another galaxy. They come from countryX's homes, countryX's parents, countryX's schools, countryX's churches, countryX's business...

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...
