Finally we have access to PSS SDK and we can make any game we want for Vita. But have anyone wonder about comparing Vita to PSP?
While porting my game from PSP/C++ to Vita/C# I stumbled across really strange behaviour - game was slower on Vita than on PSP... I don't mean rendering speed but simple computation speed done by cpu.
Today I wrote small tests for booth consoles and results are quite interesting. (PSP cpu was set to 333 MHz, on Vita only one core was used to perform calculations)
Small number of milliseconds is better.
Results are little-bit disappointing for me. Sony should add ability to use C++ with sdk or heavily optimize mono vm on Vita.
