概 要Windowsで動作速度が安定しない。
詳 細Strange pacing issue, the games do not run at 100% always, but the speed fluctuates (+/- 3 or 4%).
再現手順- download fresh 0.208 binaries (32-bit or 64-bit, I have tested both) from MAMEdev
- start any game
- check the speed (watch out for small hiccups onscreen, or press F11, as that's easier to check). Any driver will do. I noticed it first on Pong (due to the ball scrolling) and verified it on Last Blade 2 (using background scrolling). This does not seem to be driver dependent at all. Not dependent on video (d3d, gdi etc.) either.

I tried compiling my own binaries (for tag mame0208) on Debian and could not reproduce the issue there.

This behavior is specific to the 0.208 binaries (on Windows, as far as I can tell), it does not happen with 0.207 binaries.
追加情報Reported on #mame and got told by Tafoid he could reproduce the issue (thanks for the help !), which incited me to report it officially.
