I found this a couple of days ago myself. It crashes my ATI Catalyst driver on the last test. The driver has to recover every time. I do like that it lets you know the CPU-to-GPU and GPU-to-CPU performance. I'm trying to break 1GB/s on the GPU-CPU bandwidth. Heres my output (before it crashes):

Interesting app, I wonder how accurate the results are...

DrSpanky is spankin wingless in GPU -> CPU, we need to see more single core GPU results & multi core GPU results as well as more CF/SLI results to compare.
 
The only operating systems officially supported are Linux 64-bit and XP 32-bit.

The test also crashes my display driver after 67108864 bytes.

Anyway here is my output:

hi everyone, I used to have exactly the same issue with my bandwidth GPU->CPU like wingless and firestrider. And it disappeared when I updated my ATI driver to the 9.11 version. I hope it's going to be the same for you guys.

see you

ps : i have a 4870 1Go
