| Flash | tupone: macsforme: I don't know much about how GL uses the GPU, but what I've learned from writing CUDA code is that memory allocation is one of the slowest things you can do on a GPU | 03:52 |
|---|---|---|
| Flash | but, I don't see any correlation between CPU memory and GPU memory (unless you use "managed" memory ... that may be an NVidia-only thing) | 03:52 |
| Flash | so the optimization in this PR isn't obvious (yet) | 03:53 |
| Flash | I'm guessing that the indices you are tracking somehow relate to GPU memory, but there should be a difference between allocating memory and copying from host to device memory | 03:53 |
| Flash | This might be a very difficult optimization | 03:53 |
| tupone | Flash: all the allocation management I'm doing on the PR is about GPU memory (I guess. I think it depends on the driver). CPU memory I don't care in this PR. And for the copy from host to device i do with the vertexData things and it is done only when data changes (or the thing is reset) | 07:20 |
| tupone | Most of the data (not yet, but in the following PR) will stay fixed there: bzflag world mostly | 07:21 |
