for reason fps jumps considerably when move mouse around on screen (on emulator) while holding left mouse button. game laggy, if touch screen (and long moving mouse around while touching) goes smooth.
i have tried sleeping 20ms in ontouchevent, doesn't appear make difference.
here code use in ontouchevent:
// events when touching screen public boolean ontouchevent(motionevent event) { int eventaction = event.getaction(); touchx=event.getx(); touchy=event.gety(); switch (eventaction) { case motionevent.action_down: { touch=true; } break; case motionevent.action_move: { } break; case motionevent.action_up: { touch=false; } break; } /*try { ascentthread.sleep(20); } catch (interruptedexception e) { // todo auto-generated catch block e.printstacktrace(); }*/ return true; }
in logcat log, fps current fps (average of last 20 frames), touch whether or not screen being touched (from ontouchevent).
what on earth going on? has else had odd behaviour before?

if you're running emulator on windows, think this explains it:
description of performance options in windows
... also, remember microsoft windows nt uses additional priority adjustments (usually 2) based on other events, such momentarily boosting thread's priority when returns i/o call, when returning user-mode subsystem call, or when receiving keyboard input.
i've seen effect many times. , took peek @ emulator using processexplorer: while can't sure, looks emulator runs under single windows thread. unless you're seeing similar performance boost on real android device, i'd assume it's effect of windows os, not androidos.
