I have a job interview in two weeks time and want to get my engine (cough) up to par within that time to make a good impression.
For dynamic geometry I’m currently using NON-indexed vertex arrays. This works fine. But I can’t help but think I’m wasting alot of memory/speed this way. I’m currently trying to optimise for GeForce so VAR is the way to go.
But would using an INDEXED array introduce a slowdown? I ask because, as far as I know, the index array has to be kept in system memory.
I’m sure it would speed things up on generic hardware, but (in VAR) I’m curious as to whether the CPU is able to send the index data to the HW fast enough to not be a bottleneck.
in short… Is it worth the effort?
