Re: [osg-users] Performance hit caused by porting from VS 7.1 to VS 9
Hi Rick, Do the express editions do full optimizations? I recall previously MS used to cap the optimization on the give away versions of VS. Robert.

The express editions does full optimizations,.. same compiler. The express version just doesn't have features for web, MFC and stuff like that. regards, Peter On Wed, Jul 2, 2008 at 9:33 AM, Robert Osfield [EMAIL PROTECTED] wrote: Hi Rick, Do the express editions do full optimizations?

Re: [osg-users] Performance hit caused by porting from VS 7.1 to VS 9
Hi Robert, Do the express editions do full optimizations? I recall previously MS used to cap the optimization on the give away versions of VS. Nope, since 2005 express (8.0 express) it's the full optimizing compiler that's included. Rick said he converted the projects for his app from VS7.1 projects, maybe that causes some options to be set to non-optimal values in the resulting projects... I would suggest making new projects in VS9.

Re: [osg-users] Performance hit caused by porting from VS 7.1 to VS 9
I had thought about maybe express being non-optimal as well, so I had some friends do the compile on their machines with a full version of VS 9, with the same results. The only thing remaining I can think of is making new projects in VS 9 as suggested.

Re: [osg-users] Performance hit caused by porting from VS 7.1 to VS 9
Do you get the same behavior if you generate fresh VS9 project files with cmake, instead of generating VS7.1 files and converting them? I'm not sure this will have any effect, but it seems like it might be worth a shot... -Paul _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rick Pingry Sent: Tuesday, July 01, 2008 3:14 PM To: OpenSceneGraph Users Subject: [osg-users] Performance hit caused by porting from VS 7.1 to VS 9 Hello All, We have succesfully ported from OSG 1.2 to the newest SVN version (well, almost newest, I think we are on 8512 at the moment).

Re: [osg-users] Performance hit caused by porting from VS 7.1 to VS 9
Yes, the only ones I converted were my own projects. I used a fresh CMake configuration with everything OSG. It might be that only my own projects are slower. -- Rick On Tue, Jul 1, 2008 at 5:45 PM, Paul Martz [EMAIL PROTECTED] wrote: Do you get the same behavior if you generate fresh VS9 project files with cmake, instead of generating VS7.1 files and converting them?
