SetGraphics "htz" doesn't work in fullscreen now?

Should say "Graphics" in the topic, sorry. Back a few versions (I only have 1.33 installed here to test against at the moment) this worked fine and you could set any frame rate you like. In the current version of Bmax it only seems to work in windowed mode and on switching to full-screen the game matches the windows refresh rate rather than the update rate given in the Graphics command. Can someone please check and make sure it's not just me? When did this change/break? It is still documented and should still work. :( |

The '30' parameter in your sample refers to the Hz the video mode itself runs in, it does not magically slow down your screen updates. Since your videocard won't support a 30Hz mode, it instead uses the default 60Hz refreshrate instead. If you only want 30 redraws a second instead of 60, you'll need to do that in code instead. |

I'm confused because it worked in previous version of Bmax. That same code running in 1.33 (for example) works as intended. |
| ||
That may be but with the latest releases we now have a DirectX9 driver. So that might be why it no longer works. |

See versions.txt for change to default flip behaviour. |
| ||
I've gone back to 1.34 to compile my project because I didn't have time to code in my own frame rate limiting before it was due for submission. |

You shouldn't switch versions mid development anyway as the behavior and potential bugs change. that makes any testing useless. |
