Tepoo: I don't know how code that multiple 2 arrays and set score to another can be that bad... If you point me my errors i will fix them C# code is from MS site for testing parallel loop and i added c++ to be similar.
Main point of this test was to show that Mono VM on Vita is really really bad optimized, or Sony limited CPU speed with PSS SDK. There are some other tests made by Martin Caine on pss forum ([Register or Login to view links]). He used built in Vector3 structure and his own.
Anyone can clearly see that Mono VM is really really bad optimized on Vita or maybe Sony limited CPU speed there... PSS SDK is still in beta state so maybe Sony will improve this. Otherwise don't expect to many advanced games on Vita made with this sdk.
