Are games meant to be slow in Intel XDK testing mode?

I tested my app on my phone in Intel XDK, and it was very laggy. It's an older version phone, so that might be a problem. It's a Galaxy S2. Are the games suppose to go in slow motion in testing mode? Also should the PhoneGap IAP plugin work in XDK? Thanks!

Unfortunately only the simplest of games will run on an S2 in "acceptable" quality. They won't run with full speed. The device is basically 2 generations too old for HTML5 stuff. Even on modern phones you have to optimize aggressively to avoid bad performance.

My Galaxy S3 is ancient right now, I'm able to keep the good framerate but i can feel I'm pushing it to the limits. S2 is a lot older and much weaker device, you should not expect miracles on it unfortunately :/

Have you tried testing your game with CocoonJS?

Eisenhans \ shinkan I'm getting a new phone soon, but i still play Clash Of Clans and other games like that with no lag. It's a pretty simple game, which i don't really care if it lags a lot on testing mode. I just want to make sure that it won't be like that when people play the game once i publish it. — I haven't yet, but it's probably just a problem with my phone.

You cannot compare that. Clash of clans is a native game. C2 exports HTML5 games, that's like 50 more layers of abstraction Wrappers like XDK don't magically make a native game out of it, they just package a browser engine with it. It's still "just" a browser game.

The newer the tech, the less a problem this is. On modern phones you can make perfectly fine HTML5 games with Construct2 that that run at 60fps.

But not with an S2.

Eisenhans Okay, but would newer phones still be able to play it okay?

Depends entirely on the game and how well you optimized it.

That said, there are a lot of C2 games working quite well on mobile devices, you just have to do it right.
