View Full Version : GL_NV_element_array performance
11-15-2002, 12:46 AM
On my Gefore4-4200 using 40.72 drivers, drawing with GL_NV_element_array is slower than the glDrawElements (using VARs for the data in both cases).
Has anyone of you a clue WHY?

You only get that extension, if you're running in NV30 emulation mode. Naturally it runs in software and is thus slow.
I think Matt stated somewhere that he doesn't think it's possible to implement NV_element_array on a GF4 in hardware...I'm not sure though ;-)

Correct, I'd recommend not using this, for that very reason. In the future there will be the ARB spec anyhow...
