Re: [osg-users] Dynamic Texture Upload affecting frame rates drastically

Hi So you might be generating mip maps for the texture. Also some older cards hate TextureRectangle, you are better off subloading a non power of two texture into a larger power of two texture. Check this code for example

Re: [osg-users] Dynamic Texture Upload affecting frame rates drastically

SMesserschmidt, thank you for your reply. However, I had already set the NPOT-resizing hint to false for all the textures I am using. This was the case when the previously attached benchmark results were created. -- Read this topic online here:

Re: [osg-users] Dynamic Texture Upload affecting frame rates drastically

Hi Abhishek, Have you tried to check if NPOT-resizing is enabled on the textures? May be some small code snippet would help reproducing. cheers Sebastian Hi, I find that uploading textures in OpenScenegraph, seems to hit performance (rendering rates) drastically. Please find attached the

[osg-users] Dynamic Texture Upload affecting frame rates drastically

Hi, I find that uploading textures in OpenScenegraph, seems to hit performance (rendering rates) drastically. Please find attached the code I have used to produce the following benchmarks. I have done 2 benchmarks: a) Using osgdb_ffmpeg to read full HD AVI file's frames (1920x1080 25FPS) into
