We had a few reports from r250 of crashes on startup. We're still not quite sure what's behind this, but we've done some upgrades to our build process since we suspect it may be related to that. Since this is an essential issue to fix, if this resolves the problem we will probably release another stable update to ensure everyone can use the latest version of Construct 2.

Secondly there have been some reports that appear to indicate a recent Windows update regressing performance opening dialogs for very large projects. Based on the timing, the fact the performance regression appears to be in Windows itself, and potentially involves a large number of system calls, we are beginning to suspect this might actually be related to the Meltdown vulnerability. The mitigation patches that have been rushed out have been known to have a major performance impact in system-call heavy code, particularly with older CPUs. To minimise the performance regression we have modified the way icons are created in "Don't show unique icons" mode. (You must choose this mode in Preferences to activate the workaround.) In this mode we make far fewer calls in to Windows which we hope solves the issue; however most of our machines are modern and don't show any serious problem, and Meltdown's mitigations disproportionately affect older CPUs, so we're keen to hear feedback from users particularly with older systems to see if this helps improve the situation.



Adjustments to build process to try to work around crash on startup issue


Changed icon management when "Don't show unique icons" is set in Preferences, to try to work around a recent Windows performance regression

The issue with dialog performance also occurs on completely empty new projects, on top of the line desktop & laptop CPUs, and versions of Windows 10 that have not been updated since late 2017. But thanks for the potential fix!

We have faith in you that you have or will soon discover the issues on start-up. We're not worried. :) I know I'M not.

My feedback on the patch (performance):
The bug still exists but is greatly improved.
The bug has nothing to do with meltdown.
The bug has nothing to do with a recent Windows update. It is since W10 release.
The bug does not affect just large projects, but also very small ones.
The bug affected even latest gen CPU's

All this was in the bug report, so I am not sure where the wires were crossed. The bug report was also closed (even though the bug is not fixed), so I am not sure where or how you want this feedback.

Since it does not say it, only those on W10 hit the issue. if you are on W7, you don't need this to mitigate the poor performance issue.

quoted from Sinkomies

because the official facebook api doesn't support it anymore and it was pointless to have those features. its facebook issue not scirra.
