Ran in to this odd problem the other day, when the platform game I was working on started to lag a bit when I tested it in Construct. The fps kept dropping, and it got worse as I went on, ended up only running at half its itended speed.
At first, I figured I was being overambitious with my paralax backgrounds, but as I have a reasonably powerful computer, and it was only a fairly small level I was testing, I was dubious. So I got rid of the paralax layers, and the problem didn't go away.
Closing and re-opening Construct worked, but only for a couple of test-runs, after that, the lag started building. To make sure it wasn't my PC at fault, I tried exporting it as an exe, which ran smoothly at 60fps every time.
Just wondering if there is perhaps a memory leak of some sort in the Construct runtime. Any ideas why this might've happened?
Also, I was doing this in version .86, as .87 messed up some of the events in the game.
