Can I make GL calls? The comment in this section about multi-threaded GL calls providing no performance increase is misleading. CPU overhead in the driver due to GL calls is in practice often a significant performance bottleneck. On all the games I've worked on we'd spend a lot of effort minimising / batching state changes for this reason (not just to reduce the GPU load) and had big performance wins.
