I've built precompiled packages as well as revised the project pages a bit.
Both are available for x86: http://22.214.171.124:8080/jxrender/
I would be really happy about feedback, especially how it works on different hardware.
There's quite a lot of hw untested (see "Driver Status"), so if you have an untested card with recent drivers it would be great if you could give it a try and report back wether it worked and which bugs you've run across.
Feedback over Mailing list is preffered, or simply leave a commend here.
