I’m experiencing bad performance for texture downloading. I don’t know whether this is caused by h/w or s/w.
Can anyone measure download time for a various sizes of textures,
using glTexSubImage2D. Say 1024x768, 720x576, 640x480?
For 720x576 I have noticed times about 40-45 ms with a GeForce2
and 700Mhz Pentium III.
If any Windows-guy could test the same hardware with both OpenGL
and DirectX I would be very thankful.
