Did author try to send image with 64 bits per pixel? It should by send to GPU without converting. But If the fullscreen is 15 megapixels, than it's ~120MB per frame.
- milansuk 10y agoNo reply, but I'm still think about it. If iMac has PCI-E 3.0 x16, It's 16GB/s throughput divided by 120MB = 136 frame per second. Of course the values are theoretical and the question is what happen in GPU.
- justinfrankel 10y agoWe render everything (for portability) in 32bpp ARGB, so that'd require conversion anyhow.
