* Call OpenGL functions directly, remove the pfifo thread, some refactoring * Fix PerformanceStatistics calculating the wrong host fps, remove wait event on PFIFO as this wasn't exactly was causing the freezes (may replace with an exception later) * Organized the Gpu folder a bit more, renamed a few things, address PR feedback * Make PerformanceStatistics thread safe * Remove unused constant * Use unlimited update rate for better pref
