Right now I am just hoping that it wont add significant overhead to OpenGL. My application already has a bottleneck on changing OpenGL states and issuing render commands and I have no idea how much of that time is spend making syscalls.
- elFarto 9y agoOpenGL implementations shouldn't be effected by syscall overhead. Historically it's been DirectX that had a syscall per draw call, but I believe both now just write the command to GPU RAM directly.
- bartread 9y agoThat's at least somewhat encouraging. Nevertheless, it sounds rather like the old, "Yes, but will it run Crysis?" question will perhaps have renewed relevance.
