Hi there, does osg work with any linux or there are specific versions where it will work. I want to install the one that will work 4 me. Thanx, Felix On 8/28/07, Robert Osfield <[EMAIL PROTECTED]> wrote: > > Hi René, > > One would expect performance to drop when you enable stereo. The > perfor

Hi Rene, The effect of enabling FSAA suggests that the performance difference is largely down to the fill limit of the graphics driver/card and unlikely to be related to the OSG. Robert. On 8/28/07, megamiller zoid <[EMAIL PROTECTED]> wrote: > > Hi Robert, > > Thank you for the response, I will

Hi Robert,Thank you for the response, I will check some older versions of the OSG and do thewalking forward in time. I tried some nvidia-settings, and different machines.The previously posted framerates were with "__GL_FSAA_MODE 4","setenv __GL_FSAA_MODE 0" (anti-alising off)made a huge impact (

Hi René, One would expect performance to drop when you enable stereo. The performance drop for QUAD_BUFFER I would normally expect to be similar to ANAGLYPHIC or the other stereo modes - a factor of two would normally be what you'd expect. A drop of 6 times is exceptional, alas I don't have a qu

Hello,I noticed that when I turn on quad_buffer stereo, applications become 6 times slower.For example when I run "osgviewer cow.osg --stereo OFF" the framerate is 283. Butwith "osgviewer cow.osg --stereo QUAD_BUFFER" it drops to 42. (while ANAGLYPHIC stereo runs with 175.)I think this has happe
