20. This may a little too technical, but do you use a forward or a deferred renderer? If it is the latter, how did you implement FSAA? Is it done as a custom post-process edge-detect filter, or have you implemented some novel algorithm for this?
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?
