There are some articles around the Net these days detailing wishlists for OpenGL 4.2. Two of the more informed ones can be found here and here. Between those two, the most interesting and common requests seem to come around DSA (direct state access) and better bind-by-semantic behavior for shaders. I’m going to lean a bit [...]
Just a few years ago, we had it easy. Optimizing a game engine was all about low-level code. Machine optimizations. Instruction counts. Black magic mathematics. As technology rolled on, however, things got more complicated. CPUs got faster while memory stayed slow, invalidating many optimization techniques relying on tables and pre-computed values while new optimizations involving [...]
