c# - Monogame running very slow on Windows Phone -


recently, decided resurrect 1 of old xna game projects , port windows universal app using monogame. managed game running (albeit little less performance) on windows 8.1, ran huge problems windows phone.

first, rendering portrait, fixed using rendertarget2d outlined elsewhere. important problem <8 fps game running at. thought might memory problem ran profiler found nothing out of ordinary (the game used 150mb).

after looking @ output window, saw mscorlib.dll throwing 5 system.io.filenotfoundexceptions every second! knew wrong couldn't find additional information on happening. must monogame because changed no code during port.

any ideas?

output (post-build)

other load calls here...

thanks thumbmunkeys, problem fixed. debugger makes game slow, not attaching debugger brings game 30fps.

this can tested deploying app using visual studio, stopping debugger , starting game on device.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
