| Post subject: | [Solved] How to Make Visual Studio Debug Builds Faster |
Hi All, Thank you for this wonderful library, this is my first post here. I want to share my findings about VS debug/release execution speed difference and how to make the debug builds faster. On my machine I had debug/release difference to be ~ 900ms vs 25ms, which is unpractically slow in debug. After searching the internet this article came up: http://randomascii.wordpress.com/2011/07/22/visual-c-debug-buildsfast-checks-cause-5x-slowdowns/ What you have to do is "In your project properties go to C/C++, Code Generation, and set Basic Runtime Checks to Default." After I've done that, I've got ~160ms vs 25ms timings, which is 5 times faster in debug, and is almost acceptable for development. Hope this helps someone, Yezo. |

Yes! This is a great trick which I have also used in the past. PolyVox debug builds are indeed slow (they perform a lot of memory accesses and these have to be validated I think) and this tip does help. |

It's also worth pointing out that you should disable POLYVOX_ASSERTS to get maximum speed. POLYVOX_ASSETS are active even in release mode unless you explicitly disable them in Config.h. |
