Re: [pygame] Some problem with WinXP Home and PyGame 1.7.1

That sounds weird. First of all I assume you 1. let the exactly same code run on Linux and Windows and 2. you start both the same way. I dont have to assume you have some other performance consumpting stuff running in background (Windows)?

How much FPS you can get is also in relation of your code. If it has to do a lot then the blitting is not that fast as it could. Guess this doesnt sound new to you.

About the slowdown in full screen mode. Can you set the resolution on Windows in fullscreen the same rate as the OS currently have (1024x784)? How much Hz you get then?

Just some foughts...

Eespecially point #7. Unless you really *need* hardware double- buffered
surfaces and I haven't followed your discussion properly :)

What I really need is more FPS. The fact is that on my GNU/Linux development
box (an old Celeron 800 MHz, 256 MB RAM) I get 50-60 FPS (and that's
enough). On my testing machine (Celeron 2.4 GHz, 512 MB RAM, working under
GNU/Linux) I get 200-300 FPS. But on the same (faster) machine, but working
under Windows, I get only 15-25 FPS. And that's not enough.

I have thrown this HWSURFACE and DOUBLEBUF away. I'm updating all the
modified rects on the screen (just the same way I'm doing it under
GNU/Linux), not the entire surface, and the result is still much worse.

Besides there's another problem. My app works in fullscreen mode. On my
GNU/Linux boxes I get the same refresh rate, as in my normal mode
(1280x1024) - 85Hz. But under Windows I work in 1280x1024 at 85Hz, but
after switching to fullscreen 800x600 I get only 56Hz. Why?

I don't get it. I always thought that Windows is the easier platform to
programm games, that everything works better and faster than under
GNU/Linux. And now I'm experiencing such a problems...
