[WIN] System Requirement for PTBGL-WIN

1
Mario,

Thank you so much for starting to port PTBOSX to Windows.
I downloaded it using "DownloadPsychtoolbox" and tried some demos.
However, all of the demos presenting the stimulus didn't work on my old laptop
(IBM X23 (ATI Mobility Radeon) + MATLAB7SP3.)
According to the diagnostic message, there is something wrong
with the video chip, I guess.
So, I'd like to know the system requirements for PTB-OpenGL for Windows.
I understand that it is still under beta release. However, could you please
let me know what windows machine (and video chip) you use for developing it,
specifically with a laptop?

Thanks,

Yasuo

Mario,


Thank you so much.
Screen('Preference', 'SkipSyncTests',1) works fine for my PC.

I was confused of using Screen('Preference', 'SkipSyncTests',1) and
Screen('Preference', 'VisualDebugLevel', level).

Thanks again,

yasuo
