Check if the development branch which doesn't use doubles works with my GPU #49

@tarelli ping! Put this on the command line device=gpu. Let @skhayrulin know about outcome!

If I run with device=gpu, it breaks, on macbook air. It's uptodate with origin/development

Hi @wilzh40, you can try comment this lines it should turn off double precision extension. Please let me know if it works for you. On other devices on which I run Sibernetic didn't throw such error.

It works for me now, but same bad FPS. I'll try running this on my laptop later with an actual GPU.
