Pygame Reduce Cpu Usage
Otherwise you're seeing the same image posted repeatedly. use_prediction = list(args).pop(0) if not use_prediction: self._rebound(0.0) ## Speed step needs to be adjusted by the value of interpolation ## at the time the ball collided with an edge (predictive_rebound_*). python cpu share|improve this question edited Jun 23 '13 at 1:03 asked Jun 22 '13 at 0:10 coding_corgi 4844916 2 without wait the CPU goes 100% because that is what Psymaster wrote: while 1: for event in pygame.event.get(QUIT): sys.exit() pygame.event.pump() this is the part of your program that is burning cpu. http://1pxcare.com/cpu-usage/how-can-i-reduce-cpu-usage.html
How can "USB stick" online identification possibly work? These tips assume the stock (unmodified) settings are used. 1. you simply call "pygame.time.wait(1)" somewhere in your mainloop. nice lowers the CPU available to an application.
Pygame High Cpu Usage
Looking at the output, note that the memory usage is expressed in terms of MiB, which stand for mebibyte (1MiB = 1.05MB). 7. Thanks to Koen Witters, DR0ID, and Glenn Fiedler for sharing. if self._paused: if self.paused_callback: self.paused_callback() return # Check if update and frame are due.

- if you don't care about the mouse movement you can block those messages and save even more cpu time.

Why do shampoo ingredient labels feature the the term "Aqua"? Of course, if you're shooting very fast bullets it would matter, but that doesn't apply to our demo. Incidentally, if you say "start_time = time.time()" when starting your program, then get the time when ending, subtract start_time, and divide by the number of frames drawn, you get an easy self.clock = pygame.time.Clock() ....
calling Sleep(0) (underlying system API) just releases the rest of your current timeslice. Pygame Event Wait At any moment that there are no other processes, OP's code will still use 100 % CPU and if there are, they will use the CPU, totaling again at 100 %. Are there any rules of thumb for the most comfortable seats on a long distance bus? You could certainly use the GameClock simply as a timer and FPS throttle, but that only scratches the surface.
What's the male version of "hottie"? If that fixes the problem, then the SDL_Delay which is used internally by pygame isn't usable for this purpose.Also, print out the result of tick() function.

Pygame Event Wait
there is another 'wait' function in the event module.

Either method will allow other programs to run faster, reduce needless wear on the computer, and (especially useful for laptops) use less energy. Authentication Error for ABBY Ocr Sdk! So it ends up being a pretty os ambigous game still.
First, it should make a positive difference in the user experience.
And we see the ill effect is resolved when we turn on screen-edge collision prediction (enabling with the P key). for pygame related questions, comments, and suggestions, please see help (lists, irc) Marina Mele's site Learn about Python, Django, Marketing and Science Menu Home Python Django TaskBuster Django Tutorial Other things SETTINGS = ( # TicksPerSecond MaxFPS (TICKS_PER_SECOND, 0), # unlimited FPS (TICKS_PER_SECOND, MAX_BALL_SPEED / 2), # max FPS is half ball speed (TICKS_PER_SECOND, TICKS_PER_SECOND * 2), # max FPS is double if you go all the way up to wait(5) the program will definitely be under 1%.
This is easier than trying to shoehorn all that logic into a single loop and select based on game state. sprite_group.clear(screen, eraser_image) for ball in sprite_group: ball.predict(interpolation, USE_PREDICTION) sprite_group.draw(screen) pygame.display.update() def handle_collisions(): """Handle collisions for both Pygame clock and GameClock.""" for sprite in sprite_group: for other in pygame.sprite.spritecollide(sprite, sprite_group, False): Project Coordinator Contract at Milton Public Library Web / Game Developer Contract at Milton Public Library Senior Lecturer/Lecturer Game Technology in Programming Full-Time at NHTV Breda University of Applied Sciences Latest http://1pxcare.com/cpu-usage/windows-reduce-cpu-usage.html In the worst case where the CPU cannot keep up with the game load, game time will subjectively take longer but still remain accurate enough to keep game elements in synchronization.
This is done by separating the game mechanics routine from the display routine and calling them on independent cycles. Browse other questions tagged python python-3.x pygame pyglet or ask your own question. using this method the program really will take 0% of the cpu, unless the user is interacting with the program. writing to a file is much cheaper. –ppumkin Jun 23 '13 at 13:07 @ppumkin Ha ha, thanks! –coding_corgi Jun 23 '13 at 13:57 You need to tell
Why are copper cables round? Splinter of Chaos' advice worked. When Predict is off predict() assumes it will never change course, and update() snaps it back from the predicted position. Install it with $ pip install guppy 1 $ pip install guppy Next, add it in your code as: from guppy import hpy def random_sort3(n): hp = hpy() print "Heap at
this would be more useful in larger games, but overkill for an image viewer. Forli Apr 9 '15 at 1:44 Is there a reason why you don't want to use pyglet's display window for playback? It may not be the main issue, but you may want to try creating the rect outside of the loop and see how that effects cpu use. Schedule frames at capped frames-per-second, or uncapped. 4.
