We shipped our game to some beta testers but some of them cannot start the game with no error message. I guess the used CPUs can be the Problem:
Core i7 950
Core 2 Quad Q6600
AMD Phenom II X4 955
AMD Phenom II X6 1100T
Mayby CPU instruction sets are not enough for UE4. All of this CPUs have no AVX Extension but the AMDs have SSE4a. In the UE4 source code AVX seems to be disabled. Maybe it is enabled in the Launcher Version?
We have shipped our previous game with UE 4.8. This runs at the Core i7 950 (the other ones are not tested).
Could you please provide me with the DXDiag from each of these computers, or at least provide me the basic information such as their graphics card and the ram? Also, what type of game did you make? Is it heavy in graphics, or anything like that?
