Scene - max width in pixels that a PC can handle?

I was wondering what is the maximum width in pixels a scene can have, so that it runs smoothly on an average PC and that Construct 2 would be able to handle?

20 000 pixels? 50 000 pixels? 500 000 pixels?

There wouldnt be too much sprites I dont think, maybe max 5 per scene with instances, mostly a background that fills the whole scene.

Having a background that fills the whole scene sounds like a bad idea..

Yes I see, but the idea is that it would be a top-down view of the ground only, just 1 long sprite. So basically you are saying that its better to solve this using tiles then eh?

Ps. The background sprite would have no animation and be static only.

EDIT: I was thinking of going with tiling background but that causes problems with scaling in Construct 2, in regards to some tutorials that I have followed.

P.s. Thanks for the link, good read.
