At worst you could use sleep As to Vertical retrace you have the OSG source code just look at what V key press calls
Personally to me I think it perfectly reasonable to set this myself, the less forced defaults the better for me, but thats my preference And there are many graphics cards that still do not allow you to set the V sync through code only through the driver interface Best Regards Gordon __________________________________________________________ Gordon Tomlinson Email : gordon.tomlinson @ overwatch.com YIM/AIM: Gordon3dBrit MSN IM : Gordon3dBrit @ 3dSceneGraph.com __________________________________________________________ "Self defence is not a function of learning tricks but is a function of how quickly and intensely one can arouse one's instinct for survival" - Master Tambo Tetsura -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of David Johansson Sent: Friday, October 13, 2006 11:32 AM To: osg users Subject: Re: [osg-users] Reduce cpu load. Thank you Robert. 2 more questions though :) It must be possible to set vertical sync at runtime, since you do it by pressing 'v' when using osg::Viewer. I don't feel that it's a good solution to ask the user to set this manually. And second, do you know if there is a function in Windows API, and/or Linux that will "idle" the cpu for a number of milliseconds. I would really prefer to do this manually. Thanks for all the help!
