I have a 1700X, and last time i compiled it was about 20 mins (but that was 4.15). I could do a full recompile this evening, if you’re interested.
PS: Visual Studio is at least using 12 cores of the 16, never bothered to get them up to more, since i normally do some work on the side while compiling.
Did another test today, I did a build of VXGI branch.
Engine build took 37 minutes. While the engine was building I had another instance of VS running with debugger attached on a project on which I was working.
R7 1700 stock (3.0 Ghz) with 16 Gb DDR4 3200 (<- maybe thats a thing since performance with infinity fabric increases with memory speed since its clock at memoryspeed/2…still shouldnt boost by that much).
I will do a full build with oc to 3.7 later, with a freshly restarted pc and cleaned projects, maybe i forgot something
