MMF2 + lens object=Horrible slowdown :(

[joewski]

[]Lens is a very "heavy" object. It is doing heavy maths and read every single pixel in the lens image 50 time per second. This is very slow so try to keep your lens images small to run a decent speed on lower end computers.

Since lens is doing pixel by pixel checks, for some reason, turning DirectX on (in your application properties) slows Lens down. If you also enable VRAM, Lens will cause your game/app to run extremely slow. I'm sorry I can't fix it. So if you want decent speeds, keep your fingers off DirectX and VRAM <img src="/center/images/graemlins/wink.gif" alt="" />

A tip for improving speed:
Turn off autoupdating and use the 'Manual update' action when it is needed, for example when Lens is overlapping a moving object that requires the lens object to distort the background once again. If autoupdate is turned off, the lens will keep its last distorted image and whon't use CPU on rendering a new one. [/]

From the help file about speed!

Ah, uhm...RTFM <img src="/center/images/graemlins/smile.gif" alt="" /> i forgot.

I tried to change the framerate with following results:

50 FPS: slowdown (but not continuously, sometimes faster, sometimes slower)

70 FPS: all right!

and now the surprise: 25 FPS is also all right (the mirror effect is slower, but continuously. the zoom and origin effect are fast like with 70 FPS)

Hmm crazy :S
Could you try sending me a little example on that please? <img src="/center/images/graemlins/smile.gif" alt="" />
Might be something in the code slowing it down, It would be neat with an example to test changes in the code on.

It is the original Lens.mfa in the examples-directory.
Just added a frame rate counter.
