41:00 “I don’t mind blocking for the 1.2 milliseconds it will take for this to come in from flash.”

Carmack is talking about the difficulty of loading resources while rendering. This is mostly a problem with multi-threading.

28:30 “You can put multiple Titans into a PC and render absolutely incredible amounts of FLOPS and Vertexes and Textels”.

He’s talking about the huge horsepower of top-end PC’s. You can put multiple Titan graphics cards into a single PC so they can share the load and work even faster. (This is insanely expensive, but also insanely fast. I think one Titan will set you back about a thousand bucks, as of this writing.)

FLOPS are FLoating-point Operations Per Second. When we’re talking about how fast a processor can crunch numbers, we often measure performance in FLOPS.

A texel is a “texture pixel”, and in this context it’s basically a measure of how fast the graphics card can fill up the screen with all the stuff it’s trying to render.
