ue4     It’s been a month since UE4 was released to the public. During this time many of you were probably wondering: “Does my PC handle new engine?” It’s possible to find tests that compares fps in editor for template projects. But it was impossible to find something that refers to compilation time, especially that compares HDD and SDD drives. I know that compilation time depends mostly on CPU performance, but speed of IO operations are still important. This is the reason why I’ve performed my own tests.

Test case: Full compilation of all C++ engine sources

During these tests Visual Studio was the only one application executed by the user. Each core of tested CPU’s was used in 100%. Each test was performed once, other tests gave mostly the same result.
