With things like weather and temperature affecting more and more things planetside, has there been any consideration for things like heat wave or shimmer effects?

Yes. We used to have them, exactly, Jared. We used to have them on the CPU particle system. Again, we've moved all of our planet effects to the GPU, but we didn't have refraction there. So a refraction particle getting that heatwave look wasn't available to us. So once we get that on the GPU, then we can put the shimmer back in.
