When you load via the Epic Launcher, you are using the Epic Launcher Pre Compiled Binary version, which I believe goes live with 5.0 EA " on 25th June?. I am building from the Git hub source not the zip file. I have already got VS 2019 loaded, and like @Knauric has said the complier probably shares with VS2019. When we moved from VS2017 to Vs2019 initially we need to have VS2017 loaded as well as VS2019, because some code was initially shared or pointers needed adding. I would in hindsight, load VS2019 as well as VS 2022.
The Valley of the Ancient relies on the faster graphics card than mine. However the code seems to run quicker and on a slower graphics card this is noticeable, but if I had a fast graphics card I dont know if it would be that much faster!.
My motive for all this has been to find any bugs or problems, which will get fixed quicker. The Visual Studio teams always want people with big projects to test, or try and break, the new compilers, and that’s what I like doing!
