how slow is full screen canvas on your machine

Anyone who has a free moment, can you do a quick expirement for me?

Take any current construct project and turn on the fps display.

edit: the higher the resolution the better

See how many fps you get

Then add a canvas that takes up the whole screen and gets a sprite pasted to it every tick

And post the before and after fps here along with your pc specs, and what resolution it was running at

Considering using it for an effect in my game and I know full screen canvases kill some machines, trying to figure out if its the majority, or the minority, and at least if it works fine with most peopl with semidecent gaming pcs

I tried it out and didn't find much difference besides vram usage (although, I did just get a brand new Nvidia card today ).

Before: 85fps, 0.06mb vram

After: 85fps, 2.14mb vram

Specs:

Cpu - Intel P4 2.8Ghz

Graphics Card - XFX Nvidia Geforce 210 (512mb)

thanks

and also, forgot, what resolution?

800x600 windowed (I assumed full screen meant stretched across the whole window)

1024x768 unlimited FPS, canvas over entire screen

Canvas: 470 FPS, takes 7mb VRAM

No canvas: 710 FPS

Athlon II X2, GeForce 9500 GT

1920x1200, Intel C2Q Q6600 2.70 GHz, Nvidia GeForce 9600 GT 512 MB

No canvas: ~1480 FPS

Canvas: ~900 FPS
