Start your Game or make a preview in NWjs. Press F12, Click on the Tab Console. Type process.versions['node-webkit'] and press return.
That's way too complicated. Just right-click "nw.dll", and then check out the product version under "details", inside the application properties.
I've tested with other people. This phenomenum doenst happen with VERY STRONG processors, like 3.0 Ghz...
If you can find the cause for this and provide a minimal project for reproduction, I will report it to the NWjs team for you.
Pretty much adding to what Asmodean said:
- Press F12 and check for console errors
- If you got any 3rd party plugins, try testing without them
- Update to the latest stable version of Construct 2
