After I upload vertex data to the GPU using VBO (glBufferData), Is it safe/possible to delete the original data store in main memory ?
I tried deleting data in main memory but when i call glDrawPixel to render VBO the scene go blank
I also noticed that there no performance increase
comparing vbo to generic vertex array, the framerate are almost the same
*note that i did'nt use indexing and draw as a GL_TRIANGLE
I use Gefore 7600gt with 93.71 driver (windows XP)
my code also work on Gefore4MX (does GF4MX even supported VBO ?)
