Ocra built executables take a minute to launch on Win8 / Win10

[shawn42]

When launching my Gosu game executable on Windows 8 or Windows 10 the game takes about a minute to launch but launches in a few seconds on Windows 7.

Links to the windows build and the source can be found here: http://ludumdare.com/compo/ludum-dare-33/?action=preview&uid=571

Any ideas on what could be causing this? and / or any work arounds?

@larsch My testing on Win8 shows that the first run in about 60s (in a VM). Subsequent runs are about 5s. Possibly a delay while windows loads legacy libraries? Maybe we need a pre-win8 build and a post-win8 build of ocra?

I'm not seeing this on Windows 10. In my experience, Windows Defender and other virus scanners are quite aggressive with "Unknown" executables - perhaps this is causing the slow down. You could try and monitor the executable with procmon from sysinternals, so we can see what's going on.

@larsch Can you try the Windows link from my Gosu game packaged up with ocra: http://ludumdare.com/compo/ludum-dare-33/?action=preview&uid=571 Also, can you post the exe you are using for testing and I can test it on my setup. Thanks again!

PixelMonster needs 13 seconds to start in my Windows 10 VM, running off an external HD via VirtualBox (which tends to be slow). So definitely faster than for you @shawn42, but still not as snappy as it should be. Shutdown took ~2 seconds.

@jlnr thanks for the data point, do you have a copy of win8 to test on?

Nope, I think what matters more is whether I have Windows Defender running or not. I honestly don't know :) I'll verify that first.

I was able to test this on my new Win10 machine (with defender on) and the game starts in a few seconds. I will retest on Win8 and post my findings.

Assuming no longer pertinent, closing.
