Problem with Winuae and 50hz to 60hz

My lcd monitor is fixed at 60 hz and 75 hz screen refresh rates.

When I select 60hz in winuae to make the moving objects smooth (like scrolling games etc) weird things happen like faster games, clock going insane.
And there is a visible scanline effect from up to down that tears moving icons in two.

I have a similar thing going with my real Amiga with CybervisionPPC with CyberGfX. Somehow I think even the VGA monitors refresh rate is tied to Amiga's custom chips in a way. Ie: I set the refresh rate to 60hz using AHI tool to set Paula 22khz to higher and instantly my 1024-768 16 CGX screen via CVisionPPC becomes much smoother. (when I created a resolution with 60hz refresh)

Is it possible to set the refresh to 60hz but not make it ntsc speed? Or is it a limitation (or feature) of Amigaos?

I know the question sounds a bit stupid. But this is the most technical I can get in English

Vsync enabled = everything is synced to selected refresh rate. Thats how Amiga hardware works.

so is it possible to "at least" make the coputer run at 60 or 75hz at vga screens but immediately revert back to pal 50hz when I run a game or a demo?
