> jReality uses a lot of display lists. Nowadays, they are badly implemented, the most accelerated paths use VBOs.

Contrary to popular belief VBO's aren't the fastest way to submit static geometry to the GPU. Display list are just fine or even better "the fastest way to send geometry" to the GPU (at least on NVidia GPU's). Take a look here for further details: http://www.gputechconf.com/page/gtc-on-demand.html#session2127 (slide 101).

So "jreality using display lists" isn't the bottleneck here. Maybe stg else is wrong with jreality or the code ...
