Windows rtt glreadback testing

In the next Max release, rtt mode will be default for Windows, as it already is for Mac.

In the meantime, we would love to get some feedback to see if this works for most people's patches/graphics cards/drivers.

In order to have Max start up with rtt mode as the default glreadback mode, create a text document with the following:

jitter glreadback rtt;

Title it 'jitter-config.txt' and save it somewhere in Max's search path, though not in the 'init' folder. For example, I saved mine in Max 5.0/Cycling '74/.

If you do experience any problems, please send an email to support at cycling 74 dot com, with your system specs and a simple patch with steps to reproduce. It may be that with older cards/drivers, ctt will perform better, but with most modern harddware rtt is probably the way to go for now.

Thanks for playing along!
