Tooltips kill framerate
Blitz3D Forums/Blitz3D Programming/Tooltips kill framerate
| ||
| I've noticed something very odd that always seems to happen with Blitz3D when running in windowed mode. If I hover the mouse over something, like a taskbar icon, and a tooltip appears, the Blitz3D program starts going at a real crawl. I've had it go from 200 FPS to 1 FPS. Anyone know why? Blitz3D bug? |

| Driver issue? I just tried out a program I'm working on. Approx 200 FPS, doesn't decrease at all when hovering over an icon. Another thought, maybe your system is slow? I know blitz likes to hog CPU cycles from windows. If your system is slow and Blitz is grabbing 100% of the CPU, then activating someting like a tooltip will require some CPU cycles so Blitz framerate will drop, although I can't imagine it dropping that much just to open a tooltip. |

| Hmm. Must be a driver thing then. If I stick a Delay 5 in the loop it doesn't make a difference, so it's not that Blitz is using all the CPU cycles. |

| Ok, I take back my last post. I was running the program in debug mode. When ran in release mode, I get approx 400 fps, but when I hover over a taskbar icon, the framerate drops to about 230 fps. However, I did notice that when I ran the program, the CPU usage jumped from less than 1% up to 100%, so I still think it's from the tooltip stealing cycles from blitz. |

| 400 FPS? I don't get that with a blank screen. |

| Rottbott: Use "Flip 0" to update as fast as possible.It is never normally required to update faster than the screen refresh rate.... |
