I HAVE A QUESTION...

In many PCs the construct2 games in HTML go slows....

These games will be so slows also using an exporting as EXE, iOS or APK ?????? Or they will go better? :))

Not sure what an APK is, but for the others... it will usually go slower. <img src="smileys/smiley5.gif" border="0" align="middle" /> But the tech is changing all the time, and it only gets better and faster from here on out.

APK's are Android Applications. Think of an .exe, but for Android. As for the speed of things, what browsers are you using? It should run really smoothly on any recent (3-4 years ago or newer) computer. Now for the mobile, it depends heavily on how you get it on there. Do you use Phonegap or CocoonJS? PhoneGap isn't really built for mobile gaming. But in time, hopefully HTML5 will grow on the mobile field. But for now, it's best used for browsers or Windows .exe binary.

The number 1 reason a computer is slow with a HTML5 game is because the graphics card driver is out of date. Try updating your drivers. Also if you're not using Chrome already give it a shot - I find it's the fastest overall.
