Hi, I have a framerate problem with my game. There wasn't any problem with the framerate on my pc. fps was 60 and game was good running. Even with many objects. Now I tested on a different pc and framerate is down and the game "shakes". Especially ref is very high. Have anyone an idea why the framerate breaks down? The pc with the low framerate: ATI Radeon HD 4300/4500 AMD Athlon 64 x2 DualCore Prozessor 5200+ 2.7 GHz 2 GB MB Ram the screenshot:

The fps contribution of certain elements can be seen in the [F11] panel in ms per frame. In some cases it can be larger than the real rendering time by the engine and hardware, especially in fullscreen mode in which the frame rate is limited by the monitor frequency (mostly 60 Hz on LCD screens and 70..80 Hz on CRT monitors).
Monitor frequency and fps
In fullscreen mode, DirectX keeps the frame rate always in sync with the monitor frequency between 60 and 80 Hz in order to avoid tearing artifacts. The screen refresh is artificially delayed for matching the time when the monitor has finished its video cycle. This delay is visible in the 'screen refresh' time in the [F11] panel. Thus you'll never get a higher frame rate than your monitor can display. Your frame rate will be an integer division of the monitor frequency (such as 60, 30, 20, or 15 Hz when the monitor frequency is 60 Hz). When the frame rate is close to the monitor frequency, a small change of the rendering time will cause the frame rate to suddenly jump from 60 to 30 fps or vice versa. What I find mildly confusing though is that your entity rendering (and code execution) is low in execution time/ ms but only your refresh time is so high. This should result in a much higher framerate in windowed mode, can you post a screenshot of the latter, too? Do you use fps_max (and/ or fps_min)?

Sounds a lot like fillrate problems to be honest.
The thing is, what is your question? The FPS breaks down because you switched computers. Just because it runs on your PC at 60 FPS doesn't mean it's locked to 60 FPS on every computer ever, obviously the other one is weaker than yours in at least one point. Without knowing more, it's impossible to tell why your FPS breaks down, which is something you should find out by profiling your game.

what about this HD 4300/4500 thing ?
Does it have dedicated memory or take bytes from system RAM?
If so when you shouldnt wonder. Its just the crappy videohardware.
