I had a little unannounced demo today. I had bits working, and it seemed to make a relatively good impression.
As it turned out, the alternate blinking is indeed problematic, as Windows on the computer I got has severe scheduling problems. I wish I hadn’t worked on such a tight schedule, so I could re-install it (with Linux, of course).
I got an other computer today: it hasa Quadro 600 GPU, some reasonable amount of RAM and CPU. However, I found a bug in the display driver: when you select an ‘unsupported’ resolution, the display refuses to work after a reboot. The resolution I set was supported by my monitor and worked – until I had to reboot. The only way to restore display is to boot in safe mode and uninstall the driver. I don’t know where the per-display settings were stored (as opposed to /etc/X11/xorg.conf or …/xorg.cond.d/*), so I got one more shot.
Thankfully, using the latest, driver solves this problem.
There is a 64-bit version of Psychtoolbox, and I am installing it right now. As of this moment, I am in a dependency hell because of that. But not for long!
