Lecture 23: How GPUs work (1)

The unreal engine has gotten even better since 2015! Check out this video from earlier this year: https://www.youtube.com/watch?v=zKu1Y-LlfNQ

The graphics literally look like real videos and images!

More relevant to our overall discussion of GPUs, but NVIDEA's RTX graphic cards support realtime ray tracing https://developer.nvidia.com/rtx/raytracing which as we learned is much slower than traditional methods. They've allowed this on older generation cards, but that performance is really bad

Other than software advances we've had and a growing appetite for aesthetics and imaginations, it is really the compute power we gained through the past decades that we need to appreciate when we look at how gaming and animation graphics have grown.

Wow the results of that Unreal Engine demo are insane! If you like Minecraft you might enjoy this demo of a ray tracing mod someone created: https://www.youtube.com/watch?v=ekG2q_eYCAM

Indeed, those game engines are outgrowing their original purposes due to increased graphics capability. For example, you can use Unity to make pretty awesome cinema like this one: https://www.youtube.com/watch?v=GXI0l3yqBrA

The Unity demo from @fywu85 is incredibly impressive. I'm still in awe regarding the real-time aspect, although real-time when you know all the inputs before hand seems a step removed from real-time in a true video game sense where you can interact with the environment.
