GPU plotter hangs at the same percentage

  • I was plotting a 50 GB file in direct mode using the GPU plotter. Everything was going fine to begin with and the progress reached about 24 percent after 10 minutes. But, the progress percentage stayed the same for another 4 hours and nothing seemed to happen. Checking the task manager, it seemed like the RAM was buffered up, but it didn't move either. I was just about ready to give up when I clicked inside the command prompt, and then pressed a random button on the keyboard. Suddenly it started working again, and the percentage moved upwards and everything went back to normal. Then it happened again some minutes later, and this was also resolved by pressing a random button again, until finally completing.

    Any idea what causes this behaviour? If I was going to leave the plotter alone this behaviour would prevent me from getting much plotting done.
