19. What is your experience with OpenGL drivers? Do you routinely encounter bugs on either vendor that force you to implement workarounds? Do you use multiple code paths, not only per hardware level (SM2, SM3, SM4), but also per-vendor?

21. What approach do you take for GI (Global Illumination)? SSAO or something newer/better?
22. What are your thoughts on OpenCL? Are there any plans to use it for e.g. physics in the future?
Edit: 23. What is the triangle budget for a typical scene?
