Is possible to do some optimalization in this command? As you can see garbage collector takes much time...
Code Select
Texture tex = new Texture(width, height);

Using the constructor should create no garbage at all...it's more likely the uploading to the GPU or something. Not much that i can in this area though.

BTW: How often are you doing this? Constantly creating textures at runtime isn't a very good idea performance wise (let along the GC issue).

this is just example how expensive it is... ok i will be often trying to avoid creating new texture

I see. As said, uploading creates some garbage but that's unavoidable.
