No, the 39ms are from the timing measurements I did on the readback alone. I still have to try to make that faster, currently I do a simple readback, not the nvidia workaround you did in your sample....

Hi,

I ran the timing tests on my project, with the following results:

16384x2048 readback
min: 39.0039 ms (3,2GB/s)
