Weird FPS problem.

Hi

I have set the FPS to 60 and i'm using a 'RTS like' scrolling. Meaning if the mouse is on the right border of the frame, the frame goes to right, if it's left, the frame goes left, etc.

Sometimes when i scroll it's really laggy. I started deleting things to cancel out possible causes for the lag but that didn't help. Even happens when i just use a blank frame with only a quick backdrop.

Now, i found out that if i set the FPS to 100 the lag never happens. But i read somewhere that setting the FPS to 100 is bad.

What FPS value do you use? What are the arguments against FPS 100?

Also is there a more ressource friendly alternative for 360 aiming than this:

Set Scale: Sqr(((XMouse-X( "Line" )) pow 2.0)+((YMouse-Y( "Line" )) pow 2.0))
Set Angle: ATan2(Y( "Line" )-YMouse, XMouse-X( "Line" ))

?

Thanks for the reply.
Not much point in posting the MFA since i already removed all items and all code (except the scrolling bit of course and a quick backdrop).

Scrolling code looks like this:

YMouse <= Y Top Frame+16
Center display at Y=Y Top Frame+((Y Bottom Frame-Y Top Frame)/2)-4

Same for Bottom Frame and X for right and left frame... you get the idea.

I appreciate it!

Nice idea, i'll try it out.

It's just really weird that it lags at 60 and not at 100 FPS.... even though it's constantly at 60 and not dropping.
